-  ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,

-  ansi2knr.c is NOT covered by the above copyright and conditions, but instead
-  by the usual distribution terms of the Free Software Foundation; principally,
-  that you must include source code if you redistribute it.  (See the file
-  ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
-  of any program generated from the IJG code, this does not limit you more than
-  the foregoing paragraphs do.
-
-  The Unix configuration script "configure" was produced with GNU Autoconf.
-  It is copyright by the Free Software Foundation but is freely distributable.
-  The same holds for its supporting scripts (config.guess, config.sub,
-  ltconfig, ltmain.sh).  Another support script, install-sh, is copyright
-  by M.I.T. but is also freely distributable.
-
-  It appears that the arithmetic coding option of the JPEG spec is covered by
-  patents owned by IBM, AT&T, and Mitsubishi.  Hence arithmetic coding cannot
-  legally be used without obtaining one or more licenses.  For this reason,
-  support for arithmetic coding has been removed from the free JPEG software.
-  (Since arithmetic coding provides only a marginal gain over the unpatented
-  Huffman mode, it is unlikely that very many implementations will support it.)
-  So far as we are aware, there are no patent restrictions on the remaining
-  code.
-
-  The IJG distribution formerly included code to read and write GIF files.
-  To avoid entanglement with the Unisys LZW patent, GIF reading support has
-  been removed altogether, and the GIF writer has been simplified to produce
-  "uncompressed GIFs".  This technique does not use the LZW algorithm; the
-  resulting GIF files are larger than usual, but are readable by all standard
-  GIF decoders.
-
-  We are required to state that
-      "The Graphics Interchange Format(c) is the Copyright property of

-  The Unix configuration script "configure" was produced with GNU Autoconf.
-  It is copyright by the Free Software Foundation but is freely distributable.
-  The same holds for its supporting scripts (config.guess, config.sub,
-  ltconfig, ltmain.sh).  Another support script, install-sh, is copyright

-
-  It appears that the arithmetic coding option of the JPEG spec is covered by
-  patents owned by IBM, AT&T, and Mitsubishi.  Hence arithmetic coding cannot
-  legally be used without obtaining one or more licenses.  For this reason,
-  support for arithmetic coding has been removed from the free JPEG software.
-  (Since arithmetic coding provides only a marginal gain over the unpatented
-  Huffman mode, it is unlikely that very many implementations will support it.)
-  So far as we are aware, there are no patent restrictions on the remaining
-  code.
-
-  The IJG distribution formerly included code to read and write GIF files.
-  To avoid entanglement with the Unisys LZW patent, GIF reading support has
-  been removed altogether, and the GIF writer has been simplified to produce
-  "uncompressed GIFs".  This technique does not use the LZW algorithm; the
-  resulting GIF files are larger than usual, but are readable by all standard
-  GIF decoders.

+# Android GameActivity code description
+
+The source code in this directory is copied from the AndroidX GameActivity
+release package, matching the version specified in
+ `//starboard/android/apk/app/build.gradle`.
+
+To learn more about GameActivity, refer to [the official GameActivity
+documenation](https://d.android.com/games/agdk/game-activity).
+
+## Updating instructions
+
+To update GameActivity to the latest version, do the following:
+
+1. In
+   `//starboard/android/apk/app/build.gradle`, update the dependency version
+   for `androidx.games::games-activity`. The current version is `1.2.1`, and
+   you can find the latest version from [the AndroidX games release website]
+   (https://developer.android.com/jetpack/androidx/releases/games).
+1. Build Cobalt. This triggers gradle to downloaded the release package to
+   its local cache (normally under the `$HOME/.gradle` folder).
+1. Find the downloaded game-activity package, usually under
+   `$HOME/.gradle/caches/...`. The directory structure should match the
+   structure under `//third_party/android_game_activity/include/...`. You can
+   use `find` with a specific file to locate the exact path for the package,
+   as shown in the following example:
+   ```
+     find   ~/.gradle/caches   | grep   GameActivity.cpp
+   ```
+1. Copy all C++ files for the matching games-activity version to this

+/**
+ * The GameActivity interface provided by <game-activity/GameActivity.h>
+ * is based on a set of application-provided callbacks that will be called
+ * by the Activity's main thread when certain events occur.
+ *
+ * This means that each one of this callbacks _should_ _not_ block, or they
+ * risk having the system force-close the application. This programming
+ * model is direct, lightweight, but constraining.
+ *
+ * The 'android_native_app_glue' static library is used to provide a different
+ * execution model where the application can implement its own main event
+ * loop in a different thread instead. Here's how it works:
+ *
+ * 1/ The application must provide a function named "android_main()" that
+ *    will be called when the activity is created, in a new thread that is
+ *    distinct from the activity's main thread.
+ *
+ * 2/ android_main() receives a pointer to a valid "android_app" structure
+ *    that contains references to other important objects, e.g. the
+ *    GameActivity obejct instance the application is running in.
+ *
+ * 3/ the "android_app" object holds an ALooper instance that already
+ *    listens to activity lifecycle events (e.g. "pause", "resume").
+ *    See APP_CMD_XXX declarations below.
+ *
+ *    This corresponds to an ALooper identifier returned by
+ *    ALooper_pollOnce with value LOOPER_ID_MAIN.
+ *
+ *    Your application can use the same ALooper to listen to additional
+ *    file-descriptors.  They can either be callback based, or with return
+ *    identifiers starting with LOOPER_ID_USER.
+ *
+ * 4/ Whenever you receive a LOOPER_ID_MAIN event,
+ *    the returned data will point to an android_poll_source structure.  You
+ *    can call the process() function on it, and fill in android_app->onAppCmd
+ *    to be called for your own processing of the event.
+ *
+ *    Alternatively, you can call the low-level functions to read and process
+ *    the data directly...  look at the process_cmd() and process_input()
+ *    implementations in the glue to see how to do this.
+ *
+ * See the sample named "native-activity" that comes with the NDK with a
+ * full usage example.  Also look at the documentation of GameActivity.

+2.1.4
+=====
+
+### Significant changes relative to 2.1.3
+
+1. Fixed a regression introduced in 2.1.3 that caused build failures with
+Visual Studio 2010.
+
+2. The `tjDecompressHeader3()` function in the TurboJPEG C API and the
+`TJDecompressor.setSourceImage()` method in the TurboJPEG Java API now accept
+"abbreviated table specification" (AKA "tables-only") datastreams, which can be
+used to prime the decompressor with quantization and Huffman tables that can be
+used when decompressing subsequent "abbreviated image" datastreams.
+
+3. libjpeg-turbo now performs run-time detection of AltiVec instructions on
+OS X/PowerPC systems if AltiVec instructions are not enabled at compile time.
+This allows both AltiVec-equipped (PowerPC G4 and G5) and non-AltiVec-equipped
+(PowerPC G3) CPUs to be supported using the same build of libjpeg-turbo.
+
+4. Fixed an error ("Bogus virtual array access") that occurred when attempting
+to decompress a progressive JPEG image with a height less than or equal to one
+iMCU (8 * the vertical sampling factor) using buffered-image mode with
+interblock smoothing enabled.  This was a regression introduced by
+2.1 beta1[6(b)].
+
+5. Fixed two issues that prevented partial image decompression from working
+properly with buffered-image mode:
+
+     - Attempting to call `jpeg_crop_scanline()` after
+`jpeg_start_decompress()` but before `jpeg_start_output()` resulted in an error
+("Improper call to JPEG library in state 207".)
+     - Attempting to use `jpeg_skip_scanlines()` resulted in an error ("Bogus
+virtual array access") under certain circumstances.
+
+
+2.1.3
+=====
+
+### Significant changes relative to 2.1.2
+
+1. Fixed a regression introduced by 2.0 beta1[7] whereby cjpeg compressed PGM
+input files into full-color JPEG images unless the `-grayscale` option was
+used.
+
+2. cjpeg now automatically compresses GIF and 8-bit BMP input files into
+grayscale JPEG images if the input files contain only shades of gray.
+
+3. The build system now enables the intrinsics implementation of the AArch64
+(Arm 64-bit) Neon SIMD extensions by default when using GCC 12 or later.
+
+4. Fixed a segfault that occurred while decompressing a 4:2:0 JPEG image using
+the merged (non-fancy) upsampling algorithms (that is, with
+`cinfo.do_fancy_upsampling` set to `FALSE`) along with `jpeg_crop_scanline()`.
+Specifically, the segfault occurred if the number of bytes remaining in the
+output buffer was less than the number of bytes required to represent one
+uncropped scanline of the output image.  For that reason, the issue could only
+be reproduced using the libjpeg API, not using djpeg.
+
+
+2.1.2
+=====
+
+### Significant changes relative to 2.1.1
+
+1. Fixed a regression introduced by 2.1 beta1[13] that caused the remaining
+GAS implementations of AArch64 (Arm 64-bit) Neon SIMD functions (which are used
+by default with GCC for performance reasons) to be placed in the `.rodata`
+section rather than in the `.text` section.  This caused the GNU linker to
+automatically place the `.rodata` section in an executable segment, which
+prevented libjpeg-turbo from working properly with other linkers and also
+represented a potential security risk.
+
+2. Fixed an issue whereby the `tjTransform()` function incorrectly computed the
+MCU block size for 4:4:4 JPEG images with non-unary sampling factors and thus
+unduly rejected some cropping regions, even though those regions aligned with
+8x8 MCU block boundaries.
+
+3. Fixed a regression introduced by 2.1 beta1[13] that caused the build system
+to enable the Arm Neon SIMD extensions when targetting Armv6 and other legacy
+architectures that do not support Neon instructions.
+
+4. libjpeg-turbo now performs run-time detection of AltiVec instructions on
+FreeBSD/PowerPC systems if AltiVec instructions are not enabled at compile
+time.  This allows both AltiVec-equipped and non-AltiVec-equipped CPUs to be
+supported using the same build of libjpeg-turbo.
+
+5. cjpeg now accepts a `-strict` argument similar to that of djpeg and
+jpegtran, which causes the compressor to abort if an LZW-compressed GIF input
+image contains incomplete or corrupt image data.

-.TH CJPEG 1 "4 November 2020"
-.SH NAME
-cjpeg \- compress an image file to a JPEG file
-.SH SYNOPSIS
-.B cjpeg
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B cjpeg
-compresses the named image file, or the standard input if no file is
-named, and produces a JPEG/JFIF file on the standard output.
-The currently supported input file formats are: PPM (PBMPLUS color
-format), PGM (PBMPLUS grayscale format), BMP, GIF, and Targa.
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-grayscale
-may be written
-.B \-gray
-or
-.BR \-gr .
-Most of the "basic" switches can be abbreviated to as little as one letter.
-Upper and lower case are equivalent (thus
-.B \-BMP
-is the same as
-.BR \-bmp ).
-British spellings are also accepted (e.g.,
-.BR \-greyscale ),
-though for brevity these are not mentioned below.
-.PP
-The basic switches are:
-.TP
-.BI \-quality " N[,...]"
-Scale quantization tables to adjust image quality.  Quality is 0 (worst) to
-100 (best); default is 75.  (See below for more info.)
-.TP
-.B \-grayscale
-Create monochrome JPEG file from color input.  Be sure to use this switch when
-compressing a grayscale BMP or GIF file, because
-.B cjpeg
-isn't bright enough to notice whether a BMP or GIF file uses only shades of
-gray.  By saying
-.BR \-grayscale,
-you'll get a smaller JPEG file that takes less time to process.
-.TP
-.B \-rgb
-Create RGB JPEG file.
-Using this switch suppresses the conversion from RGB
-colorspace input to the default YCbCr JPEG colorspace.
-.TP
-.B \-optimize
-Perform optimization of entropy encoding parameters.  Without this, default
-encoding parameters are used.
-.B \-optimize
-usually makes the JPEG file a little smaller, but
-.B cjpeg
-runs somewhat slower and needs much more memory.  Image quality and speed of
-decompression are unaffected by
-.BR \-optimize .
-.TP
-.B \-progressive
-Create progressive JPEG file (see below).
-.TP
-.B \-targa
-Input file is Targa format.  Targa files that contain an "identification"
-field will not be automatically recognized by
-.BR cjpeg ;
-for such files you must specify
-.B \-targa
-to make
-.B cjpeg
-treat the input as Targa format.
-For most Targa files, you won't need this switch.
-.PP
-The
-.B \-quality
-switch lets you trade off compressed file size against quality of the
-reconstructed image: the higher the quality setting, the larger the JPEG file,
-and the closer the output image will be to the original input.  Normally you
-want to use the lowest quality setting (smallest file) that decompresses into
-something visually indistinguishable from the original image.  For this
-purpose the quality setting should generally be between 50 and 95 (the default
-is 75) for photographic images.  If you see defects at
-.B \-quality
-75, then go up 5 or 10 counts at a time until you are happy with the output
-image.  (The optimal setting will vary from one image to another.)
-.PP
-.B \-quality
-100 will generate a quantization table of all 1's, minimizing loss in the
-quantization step (but there is still information loss in subsampling, as well
-as roundoff error.)  For most images, specifying a quality value above
-about 95 will increase the size of the compressed file dramatically, and while
-the quality gain from these higher quality values is measurable (using metrics
-such as PSNR or SSIM), it is rarely perceivable by human vision.
-.PP
-In the other direction, quality values below 50 will produce very small files
-of low image quality.  Settings around 5 to 10 might be useful in preparing an
-index of a large image library, for example.  Try
-.B \-quality
-2 (or so) for some amusing Cubist effects.  (Note: quality
-values below about 25 generate 2-byte quantization tables, which are
-considered optional in the JPEG standard.
-.B cjpeg
-emits a warning message when you give such a quality value, because some
-other JPEG programs may be unable to decode the resulting file.  Use
-.B \-baseline
-if you need to ensure compatibility at low quality values.)
-.PP
-The \fB-quality\fR option has been extended in this version of \fBcjpeg\fR to
-support separate quality settings for luminance and chrominance (or, in
-general, separate settings for every quantization table slot.)  The principle
-is the same as chrominance subsampling:  since the human eye is more sensitive
-to spatial changes in brightness than spatial changes in color, the chrominance
-components can be quantized more than the luminance components without
-incurring any visible image quality loss.  However, unlike subsampling, this
-feature reduces data in the frequency domain instead of the spatial domain,
-which allows for more fine-grained control.  This option is useful in
-quality-sensitive applications, for which the artifacts generated by
-subsampling may be unacceptable.
-.PP
-The \fB-quality\fR option accepts a comma-separated list of parameters, which
-respectively refer to the quality levels that should be assigned to the
-quantization table slots.  If there are more q-table slots than parameters,
-then the last parameter is replicated.  Thus, if only one quality parameter is
-given, this is used for both luminance and chrominance (slots 0 and 1,
-respectively), preserving the legacy behavior of cjpeg v6b and prior.
-More (or customized) quantization tables can be set with the \fB-qtables\fR
-option and assigned to components with the \fB-qslots\fR option (see the
-"wizard" switches below.)
-.PP
-JPEG files generated with separate luminance and chrominance quality are fully
-compliant with standard JPEG decoders.
-.PP
-.BR CAUTION:
-For this setting to be useful, be sure to pass an argument of \fB-sample 1x1\fR
-to \fBcjpeg\fR to disable chrominance subsampling.  Otherwise, the default
-subsampling level (2x2, AKA "4:2:0") will be used.
-.PP
-The
-.B \-progressive
-switch creates a "progressive JPEG" file.  In this type of JPEG file, the data
-is stored in multiple scans of increasing quality.  If the file is being
-transmitted over a slow communications link, the decoder can use the first
-scan to display a low-quality image very quickly, and can then improve the
-display with each subsequent scan.  The final image is exactly equivalent to a
-standard JPEG file of the same quality setting, and the total file size is
-about the same --- often a little smaller.
-.PP
-Switches for advanced users:
-.TP
-.B \-arithmetic
-Use arithmetic coding.
-.B Caution:
-arithmetic coded JPEG is not yet widely implemented, so many decoders will be
-unable to view an arithmetic coded JPEG file at all.
-.TP
-.B \-dct int
-Use accurate integer DCT method (default).
-.TP
-.B \-dct fast
-Use less accurate integer DCT method [legacy feature].
-When the Independent JPEG Group's software was first released in 1991, the
-compression time for a 1-megapixel JPEG image on a mainstream PC was measured
-in minutes.  Thus, the \fBfast\fR integer DCT algorithm provided noticeable
-performance benefits.  On modern CPUs running libjpeg-turbo, however, the
-compression time for a 1-megapixel JPEG image is measured in milliseconds, and
-thus the performance benefits of the \fBfast\fR algorithm are much less
-noticeable.  On modern x86/x86-64 CPUs that support AVX2 instructions, the
-\fBfast\fR and \fBint\fR methods have similar performance.  On other types of
-CPUs, the \fBfast\fR method is generally about 5-15% faster than the \fBint\fR
-method.
-
-For quality levels of 90 and below, there should be little or no perceptible
-quality difference between the two algorithms.  For quality levels above 90,
-however, the difference between the \fBfast\fR and \fBint\fR methods becomes
-more pronounced.  With quality=97, for instance, the \fBfast\fR method incurs
-generally about a 1-3 dB loss in PSNR relative to the \fBint\fR method, but
-this can be larger for some images.  Do not use the \fBfast\fR method with
-quality levels above 97.  The algorithm often degenerates at quality=98 and
-above and can actually produce a more lossy image than if lower quality levels
-had been used.  Also, in libjpeg-turbo, the \fBfast\fR method is not fully
-accelerated for quality levels above 97, so it will be slower than the
-\fBint\fR method.
-.TP
-.B \-dct float
-Use floating-point DCT method [legacy feature].
-The \fBfloat\fR method does not produce significantly more accurate results
-than the \fBint\fR method, and it is much slower.  The \fBfloat\fR method may
-also give different results on different machines due to varying roundoff
-behavior, whereas the integer methods should give the same results on all
-machines.
-.TP
-.BI \-icc " file"
-Embed ICC color management profile contained in the specified file.
-.TP
-.BI \-restart " N"
-Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
-attached to the number.
-.B \-restart 0
-(the default) means no restart markers.
-.TP
-.BI \-smooth " N"
-Smooth the input image to eliminate dithering noise.  N, ranging from 1 to
-100, indicates the strength of smoothing.  0 (the default) means no smoothing.
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images.  Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number.  For example,
-.B \-max 4m
-selects 4000000 bytes.  If more space is needed, an error will occur.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.BI \-memdst
-Compress to memory instead of a file.  This feature was implemented mainly as a
-way of testing the in-memory destination manager (jpeg_mem_dest()), but it is
-also useful for benchmarking, since it reduces the I/O overhead.
-.TP
-.BI \-report
-Report compression progress.
-.TP
-.B \-verbose
-Enable debug printout.  More
-.BR \-v 's
-give more output.  Also, version information is printed at startup.
-.TP
-.B \-debug
-Same as
-.BR \-verbose .
-.TP
-.B \-version
-Print version information and exit.
-.PP
-The
-.B \-restart
-option inserts extra markers that allow a JPEG decoder to resynchronize after
-a transmission error.  Without restart markers, any damage to a compressed
-file will usually ruin the image from the point of the error to the end of the
-image; with restart markers, the damage is usually confined to the portion of
-the image up to the next restart marker.  Of course, the restart markers
-occupy extra space.  We recommend
-.B \-restart 1
-for images that will be transmitted across unreliable networks such as Usenet.
-.PP
-The
-.B \-smooth
-option filters the input to eliminate fine-scale noise.  This is often useful
-when converting dithered images to JPEG: a moderate smoothing factor of 10 to
-50 gets rid of dithering patterns in the input file, resulting in a smaller
-JPEG file and a better-looking image.  Too large a smoothing factor will
-visibly blur the image, however.
-.PP
-Switches for wizards:
-.TP
-.B \-baseline
-Force baseline-compatible quantization tables to be generated.  This clamps
-quantization values to 8 bits even at low quality settings.  (This switch is
-poorly named, since it does not ensure that the output is actually baseline
-JPEG.  For example, you can use
-.B \-baseline
-and
-.B \-progressive
-together.)
-.TP
-.BI \-qtables " file"
-Use the quantization tables given in the specified text file.
-.TP
-.BI \-qslots " N[,...]"
-Select which quantization table to use for each color component.
-.TP
-.BI \-sample " HxV[,...]"
-Set JPEG sampling factors for each color component.
-.TP
-.BI \-scans " file"
-Use the scan script given in the specified text file.
-.PP
-The "wizard" switches are intended for experimentation with JPEG.  If you
-don't know what you are doing, \fBdon't use them\fR.  These switches are
-documented further in the file wizard.txt.
-.SH EXAMPLES
-.LP
-This example compresses the PPM file foo.ppm with a quality factor of
-60 and saves the output as foo.jpg:
-.IP
-.B cjpeg \-quality
-.I 60 foo.ppm
-.B >
-.I foo.jpg
-.SH HINTS
-Color GIF files are not the ideal input for JPEG; JPEG is really intended for
-compressing full-color (24-bit) images.  In particular, don't try to convert
-cartoons, line drawings, and other images that have only a few distinct
-colors.  GIF works great on these, JPEG does not.  If you want to convert a
-GIF to JPEG, you should experiment with
-.BR cjpeg 's
-.B \-quality
-and
-.B \-smooth
-options to get a satisfactory conversion.
-.B \-smooth 10
-or so is often helpful.
-.PP
-Avoid running an image through a series of JPEG compression/decompression
-cycles.  Image quality loss will accumulate; after ten or so cycles the image
-may be noticeably worse than it was after one cycle.  It's best to use a
-lossless format while manipulating an image, then convert to JPEG format when
-you are ready to file the image away.
-.PP
-The
-.B \-optimize
-option to
-.B cjpeg
-is worth using when you are making a "final" version for posting or archiving.
-It's also a win when you are using low quality settings to make very small
-JPEG files; the percentage improvement is often a lot more than it is on
-larger files.  (At present,
-.B \-optimize
-mode is always selected when generating progressive JPEG files.)
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-.SH ISSUES
-Not all variants of BMP and Targa file formats are supported.
-.PP
-The
-.B \-targa
-switch is not a bug, it's a feature.  (It would be a bug if the Targa format

-.TH DJPEG 1 "4 November 2020"
-.SH NAME
-djpeg \- decompress a JPEG file to an image file
-.SH SYNOPSIS
-.B djpeg
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B djpeg
-decompresses the named JPEG file, or the standard input if no file is named,
-and produces an image file on the standard output.  PBMPLUS (PPM/PGM), BMP,
-GIF, or Targa output format can be selected.
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-grayscale
-may be written
-.B \-gray
-or
-.BR \-gr .
-Most of the "basic" switches can be abbreviated to as little as one letter.
-Upper and lower case are equivalent (thus
-.B \-BMP
-is the same as
-.BR \-bmp ).
-British spellings are also accepted (e.g.,
-.BR \-greyscale ),
-though for brevity these are not mentioned below.
-.PP
-The basic switches are:
-.TP
-.BI \-colors " N"
-Reduce image to at most N colors.  This reduces the number of colors used in
-the output image, so that it can be displayed on a colormapped display or
-stored in a colormapped file format.  For example, if you have an 8-bit
-display, you'd need to reduce to 256 or fewer colors.
-.TP
-.BI \-quantize " N"
-Same as
-.BR \-colors .
-.B \-colors
-is the recommended name,
-.B \-quantize
-is provided only for backwards compatibility.
-.TP
-.B \-fast
-Select recommended processing options for fast, low quality output.  (The
-default options are chosen for highest quality output.)  Currently, this is
-equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR.
-.TP
-.B \-grayscale
-Force grayscale output even if JPEG file is color.  Useful for viewing on
-monochrome displays; also,
-.B djpeg
-runs noticeably faster in this mode.
-.TP
-.B \-rgb
-Force RGB output even if JPEG file is grayscale.
-.TP
-.BI \-scale " M/N"
-Scale the output image by a factor M/N.  Currently the scale factor must be
-M/8, where M is an integer between 1 and 16 inclusive, or any reduced fraction
-thereof (such as 1/2, 3/4, etc.)  Scaling is handy if the image is larger than
-your screen; also,
-.B djpeg
-runs much faster when scaling down the output.
-.TP
-.B \-bmp
-Select BMP output format (Windows flavor).  8-bit colormapped format is
-emitted if
-.B \-colors
-or
-.B \-grayscale
-is specified, or if the JPEG file is grayscale; otherwise, 24-bit full-color
-format is emitted.
-.TP
-.B \-gif
-Select GIF output format (LZW-compressed).  Since GIF does not support more
-than 256 colors,
-.B \-colors 256
-is assumed (unless you specify a smaller number of colors).  If you specify
-.BR \-fast,
-the default number of colors is 216.
-.TP
-.B \-gif0
-Select GIF output format (uncompressed).  Since GIF does not support more than
-256 colors,
-.B \-colors 256
-is assumed (unless you specify a smaller number of colors).  If you specify
-.BR \-fast,
-the default number of colors is 216.
-.TP
-.B \-os2
-Select BMP output format (OS/2 1.x flavor).  8-bit colormapped format is
-emitted if
-.B \-colors
-or
-.B \-grayscale
-is specified, or if the JPEG file is grayscale; otherwise, 24-bit full-color
-format is emitted.
-.TP
-.B \-pnm
-Select PBMPLUS (PPM/PGM) output format (this is the default format).
-PGM is emitted if the JPEG file is grayscale or if
-.B \-grayscale
-is specified; otherwise PPM is emitted.
-.TP
-.B \-targa
-Select Targa output format.  Grayscale format is emitted if the JPEG file is
-grayscale or if
-.B \-grayscale
-is specified; otherwise, colormapped format is emitted if
-.B \-colors
-is specified; otherwise, 24-bit full-color format is emitted.
-.PP
-Switches for advanced users:
-.TP
-.B \-dct int
-Use accurate integer DCT method (default).
-.TP
-.B \-dct fast
-Use less accurate integer DCT method [legacy feature].
-When the Independent JPEG Group's software was first released in 1991, the
-decompression time for a 1-megapixel JPEG image on a mainstream PC was measured
-in minutes.  Thus, the \fBfast\fR integer DCT algorithm provided noticeable
-performance benefits.  On modern CPUs running libjpeg-turbo, however, the
-decompression time for a 1-megapixel JPEG image is measured in milliseconds,
-and thus the performance benefits of the \fBfast\fR algorithm are much less
-noticeable.  On modern x86/x86-64 CPUs that support AVX2 instructions, the
-\fBfast\fR and \fBint\fR methods have similar performance.  On other types of
-CPUs, the \fBfast\fR method is generally about 5-15% faster than the \fBint\fR
-method.
-
-If the JPEG image was compressed using a quality level of 85 or below, then
-there should be little or no perceptible quality difference between the two
-algorithms.  When decompressing images that were compressed using quality
-levels above 85, however, the difference between the \fBfast\fR and \fBint\fR
-methods becomes more pronounced.  With images compressed using quality=97, for
-instance, the \fBfast\fR method incurs generally about a 4-6 dB loss in PSNR
-relative to the \fBint\fR method, but this can be larger for some images.  If
-you can avoid it, do not use the \fBfast\fR method when decompressing images
-that were compressed using quality levels above 97.  The algorithm often
-degenerates for such images and can actually produce a more lossy output image
-than if the JPEG image had been compressed using lower quality levels.
-.TP
-.B \-dct float
-Use floating-point DCT method [legacy feature].
-The \fBfloat\fR method does not produce significantly more accurate results
-than the \fBint\fR method, and it is much slower.  The \fBfloat\fR method may
-also give different results on different machines due to varying roundoff
-behavior, whereas the integer methods should give the same results on all
-machines.
-.TP
-.B \-dither fs
-Use Floyd-Steinberg dithering in color quantization.
-.TP
-.B \-dither ordered
-Use ordered dithering in color quantization.
-.TP
-.B \-dither none
-Do not use dithering in color quantization.
-By default, Floyd-Steinberg dithering is applied when quantizing colors; this
-is slow but usually produces the best results.  Ordered dither is a compromise
-between speed and quality; no dithering is fast but usually looks awful.  Note
-that these switches have no effect unless color quantization is being done.
-Ordered dither is only available in
-.B \-onepass
-mode.
-.TP
-.BI \-icc " file"
-Extract ICC color management profile to the specified file.
-.TP
-.BI \-map " file"
-Quantize to the colors used in the specified image file.  This is useful for
-producing multiple files with identical color maps, or for forcing a
-predefined set of colors to be used.  The
-.I file
-must be a GIF or PPM file. This option overrides
-.B \-colors
-and
-.BR \-onepass .
-.TP
-.B \-nosmooth
-Use a faster, lower-quality upsampling routine.
-.TP
-.B \-onepass
-Use one-pass instead of two-pass color quantization.  The one-pass method is
-faster and needs less memory, but it produces a lower-quality image.
-.B \-onepass
-is ignored unless you also say
-.B \-colors
-.IR N .
-Also, the one-pass method is always used for grayscale output (the two-pass
-method is no improvement then).
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images.  Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number.  For example,
-.B \-max 4m
-selects 4000000 bytes.  If more space is needed, an error will occur.
-.TP
-.BI \-maxscans " N"
-Abort if the JPEG image contains more than
-.I N
-scans.  This feature demonstrates a method by which applications can guard
-against denial-of-service attacks instigated by specially-crafted malformed
-JPEG images containing numerous scans with missing image data or image data
-consisting only of "EOB runs" (a feature of progressive JPEG images that allows
-potentially hundreds of thousands of adjoining zero-value pixels to be
-represented using only a few bytes.)  Attempting to decompress such malformed
-JPEG images can cause excessive CPU activity, since the decompressor must fully
-process each scan (even if the scan is corrupt) before it can proceed to the
-next scan.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.BI \-memsrc
-Load input file into memory before decompressing.  This feature was implemented
-mainly as a way of testing the in-memory source manager (jpeg_mem_src().)
-.TP
-.BI \-report
-Report decompression progress.
-.TP
-.BI \-skip " Y0,Y1"
-Decompress all rows of the JPEG image except those between Y0 and Y1
-(inclusive.)  Note that if decompression scaling is being used, then Y0 and Y1
-are relative to the scaled image dimensions.
-.TP
-.BI \-crop " WxH+X+Y"
-Decompress only a rectangular subregion of the image, starting at point X,Y
-with width W and height H.  If necessary, X will be shifted left to the nearest
-iMCU boundary, and the width will be increased accordingly.  Note that if
-decompression scaling is being used, then X, Y, W, and H are relative to the
-scaled image dimensions.  Currently this option only works with the
-PBMPLUS (PPM/PGM), GIF, and Targa output formats.
-.TP
-.BI \-strict
-Treat all warnings as fatal.  This feature also demonstrates a method by which
-applications can guard against attacks instigated by specially-crafted
-malformed JPEG images.  Enabling this option will cause the decompressor to
-abort if the JPEG image contains incomplete or corrupt image data.
-.TP
-.B \-verbose
-Enable debug printout.  More
-.BR \-v 's
-give more output.  Also, version information is printed at startup.
-.TP
-.B \-debug
-Same as
-.BR \-verbose .
-.TP
-.B \-version
-Print version information and exit.
-.SH EXAMPLES
-.LP
-This example decompresses the JPEG file foo.jpg, quantizes it to
-256 colors, and saves the output in 8-bit BMP format in foo.bmp:
-.IP
-.B djpeg \-colors 256 \-bmp
-.I foo.jpg
-.B >
-.I foo.bmp
-.SH HINTS
-To get a quick preview of an image, use the
-.B \-grayscale
-and/or
-.B \-scale
-switches.
-.B \-grayscale \-scale 1/8
-is the fastest case.
-.PP
-Several options are available that trade off image quality to gain speed.
-.B \-fast
-turns on the recommended settings.
-.PP
-.B \-dct fast
-and/or
-.B \-nosmooth
-gain speed at a small sacrifice in quality.
-When producing a color-quantized image,
-.B \-onepass \-dither ordered
-is fast but much lower quality than the default behavior.
-.B \-dither none
-may give acceptable results in two-pass mode, but is seldom tolerable in
-one-pass mode.
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-.TH JPEGTRAN 1 "26 October 2020"
-.SH NAME
-jpegtran \- lossless transformation of JPEG files
-.SH SYNOPSIS
-.B jpegtran
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B jpegtran
-performs various useful transformations of JPEG files.
-It can translate the coded representation from one variant of JPEG to another,
-for example from baseline JPEG to progressive JPEG or vice versa.  It can also
-perform some rearrangements of the image data, for example turning an image
-from landscape to portrait format by rotation.
-.PP
-For EXIF files and JPEG files containing Exif data, you may prefer to use
-.B exiftran
-instead.
-.PP
-.B jpegtran
-works by rearranging the compressed data (DCT coefficients), without
-ever fully decoding the image.  Therefore, its transformations are lossless:
-there is no image degradation at all, which would not be true if you used
-.B djpeg
-followed by
-.B cjpeg
-to accomplish the same conversion.  But by the same token,
-.B jpegtran
-cannot perform lossy operations such as changing the image quality.  However,
-while the image data is losslessly transformed, metadata can be removed.  See
-the
-.B \-copy
-option for specifics.
-.PP
-.B jpegtran
-reads the named JPEG/JFIF file, or the standard input if no file is
-named, and produces a JPEG/JFIF file on the standard output.
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-optimize
-may be written
-.B \-opt
-or
-.BR \-o .
-Upper and lower case are equivalent.
-British spellings are also accepted (e.g.,
-.BR \-optimise ),
-though for brevity these are not mentioned below.
-.PP
-To specify the coded JPEG representation used in the output file,
-.B jpegtran
-accepts a subset of the switches recognized by
-.BR cjpeg :
-.TP
-.B \-optimize
-Perform optimization of entropy encoding parameters.
-.TP
-.B \-progressive
-Create progressive JPEG file.
-.TP
-.BI \-restart " N"
-Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
-attached to the number.
-.TP
-.B \-arithmetic
-Use arithmetic coding.
-.TP
-.BI \-scans " file"
-Use the scan script given in the specified text file.
-.PP
-See
-.BR cjpeg (1)
-for more details about these switches.
-If you specify none of these switches, you get a plain baseline-JPEG output
-file.  The quality setting and so forth are determined by the input file.
-.PP
-The image can be losslessly transformed by giving one of these switches:
-.TP
-.B \-flip horizontal
-Mirror image horizontally (left-right).
-.TP
-.B \-flip vertical
-Mirror image vertically (top-bottom).
-.TP
-.B \-rotate 90
-Rotate image 90 degrees clockwise.
-.TP
-.B \-rotate 180
-Rotate image 180 degrees.
-.TP
-.B \-rotate 270
-Rotate image 270 degrees clockwise (or 90 ccw).
-.TP
-.B \-transpose
-Transpose image (across UL-to-LR axis).
-.TP
-.B \-transverse
-Transverse transpose (across UR-to-LL axis).
-.PP
-The transpose transformation has no restrictions regarding image dimensions.
-The other transformations operate rather oddly if the image dimensions are not
-a multiple of the iMCU size (usually 8 or 16 pixels), because they can only
-transform complete blocks of DCT coefficient data in the desired way.
-.PP
-.BR jpegtran 's
-default behavior when transforming an odd-size image is designed
-to preserve exact reversibility and mathematical consistency of the
-transformation set.  As stated, transpose is able to flip the entire image
-area.  Horizontal mirroring leaves any partial iMCU column at the right edge
-untouched, but is able to flip all rows of the image.  Similarly, vertical
-mirroring leaves any partial iMCU row at the bottom edge untouched, but is
-able to flip all columns.  The other transforms can be built up as sequences
-of transpose and flip operations; for consistency, their actions on edge
-pixels are defined to be the same as the end result of the corresponding
-transpose-and-flip sequence.
-.PP
-For practical use, you may prefer to discard any untransformable edge pixels
-rather than having a strange-looking strip along the right and/or bottom edges
-of a transformed image.  To do this, add the
-.B \-trim
-switch:
-.TP
-.B \-trim
-Drop non-transformable edge blocks.
-.IP
-Obviously, a transformation with
-.B \-trim
-is not reversible, so strictly speaking
-.B jpegtran
-with this switch is not lossless.  Also, the expected mathematical
-equivalences between the transformations no longer hold.  For example,
-.B \-rot 270 -trim
-trims only the bottom edge, but
-.B \-rot 90 -trim
-followed by
-.B \-rot 180 -trim
-trims both edges.
-.TP
-.B \-perfect
-If you are only interested in perfect transformations, add the
-.B \-perfect
-switch.  This causes
-.B jpegtran
-to fail with an error if the transformation is not perfect.
-.IP
-For example, you may want to do
-.IP
-.B (jpegtran \-rot 90 -perfect
-.I foo.jpg
-.B || djpeg
-.I foo.jpg
-.B | pnmflip \-r90 | cjpeg)
-.IP
-to do a perfect rotation, if available, or an approximated one if not.
-.PP
-This version of \fBjpegtran\fR also offers a lossless crop option, which
-discards data outside of a given image region but losslessly preserves what is
-inside.  Like the rotate and flip transforms, lossless crop is restricted by
-the current JPEG format; the upper left corner of the selected region must fall
-on an iMCU boundary.  If it doesn't, then it is silently moved up and/or left
-to the nearest iMCU boundary (the lower right corner is unchanged.)  Thus, the
-output image covers at least the requested region, but it may cover more.  The
-adjustment of the region dimensions may be optionally disabled by attaching an
-'f' character ("force") to the width or height number.
-
-The image can be losslessly cropped by giving the switch:
-.TP
-.B \-crop WxH+X+Y
-Crop the image to a rectangular region of width W and height H, starting at
-point X,Y.  The lossless crop feature discards data outside of a given image
-region but losslessly preserves what is inside.  Like the rotate and flip
-transforms, lossless crop is restricted by the current JPEG format; the upper
-left corner of the selected region must fall on an iMCU boundary.  If it
-doesn't, then it is silently moved up and/or left to the nearest iMCU boundary
-(the lower right corner is unchanged.)
-.PP
-If W or H is larger than the width/height of the input image, then the output
-image is expanded in size, and the expanded region is filled in with zeros
-(neutral gray).  Attaching an 'f' character ("flatten") to the width number
-will cause each block in the expanded region to be filled in with the DC
-coefficient of the nearest block in the input image rather than grayed out.
-Attaching an 'r' character ("reflect") to the width number will cause the
-expanded region to be filled in with repeated reflections of the input image
-rather than grayed out.
-.PP
-A complementary lossless wipe option is provided to discard (gray out) data
-inside a given image region while losslessly preserving what is outside:
-.TP
-.B \-wipe WxH+X+Y
-Wipe (gray out) a rectangular region of width W and height H from the input
-image, starting at point X,Y.
-.PP
-Attaching an 'f' character ("flatten") to the width number will cause the
-region to be filled with the average of adjacent blocks rather than grayed out.
-If the wipe region and the region outside the wipe region, when adjusted to the
-nearest iMCU boundary, form two horizontally adjacent rectangles, then
-attaching an 'r' character ("reflect") to the width number will cause the wipe
-region to be filled with repeated reflections of the outside region rather than
-grayed out.
-.PP
-A lossless drop option is also provided, which allows another JPEG image to be
-inserted ("dropped") into the input image data at a given position, replacing
-the existing image data at that position:
-.TP
-.B \-drop +X+Y filename
-Drop (insert) another image at point X,Y
-.PP
-Both the input image and the drop image must have the same subsampling level.
-It is best if they also have the same quantization (quality.)  Otherwise, the
-quantization of the output image will be adapted to accommodate the higher of
-the input image quality and the drop image quality.  The trim option can be
-used with the drop option to requantize the drop image to match the input
-image.  Note that a grayscale image can be dropped into a full-color image or
-vice versa, as long as the full-color image has no vertical subsampling.  If
-the input image is grayscale and the drop image is full-color, then the
-chrominance channels from the drop image will be discarded.
-.PP
-Other not-strictly-lossless transformation switches are:
-.TP
-.B \-grayscale
-Force grayscale output.
-.IP
-This option discards the chrominance channels if the input image is YCbCr
-(ie, a standard color JPEG), resulting in a grayscale JPEG file.  The
-luminance channel is preserved exactly, so this is a better method of reducing
-to grayscale than decompression, conversion, and recompression.  This switch
-is particularly handy for fixing a monochrome picture that was mistakenly
-encoded as a color JPEG.  (In such a case, the space savings from getting rid
-of the near-empty chroma channels won't be large; but the decoding time for
-a grayscale JPEG is substantially less than that for a color JPEG.)
-.PP
-.B jpegtran
-also recognizes these switches that control what to do with "extra" markers,
-such as comment blocks:
-.TP
-.B \-copy none
-Copy no extra markers from source file.  This setting suppresses all
-comments and other metadata in the source file.
-.TP
-.B \-copy comments
-Copy only comment markers.  This setting copies comments from the source file
-but discards any other metadata.
-.TP
-.B \-copy all
-Copy all extra markers.  This setting preserves miscellaneous markers
-found in the source file, such as JFIF thumbnails, Exif data, and Photoshop
-settings.  In some files, these extra markers can be sizable.  Note that this
-option will copy thumbnails as-is; they will not be transformed.
-.PP
-The default behavior is \fB-copy comments\fR.  (Note: in IJG releases v6 and
-v6a, \fBjpegtran\fR always did the equivalent of \fB-copy none\fR.)
-.PP
-Additional switches recognized by jpegtran are:
-.TP
-.BI \-icc " file"
-Embed ICC color management profile contained in the specified file.  Note that
-this will cause \fBjpegtran\fR to ignore any APP2 markers in the input file,
-even if \fB-copy all\fR is specified.
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images.  Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number.  For example,
-.B \-max 4m
-selects 4000000 bytes.  If more space is needed, an error will occur.
-.TP
-.BI \-maxscans " N"
-Abort if the input image contains more than
-.I N
-scans.  This feature demonstrates a method by which applications can guard
-against denial-of-service attacks instigated by specially-crafted malformed
-JPEG images containing numerous scans with missing image data or image data
-consisting only of "EOB runs" (a feature of progressive JPEG images that allows
-potentially hundreds of thousands of adjoining zero-value pixels to be
-represented using only a few bytes.)  Attempting to transform such malformed
-JPEG images can cause excessive CPU activity, since the decompressor must fully
-process each scan (even if the scan is corrupt) before it can proceed to the
-next scan.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.BI \-report
-Report transformation progress.
-.TP
-.BI \-strict

-.SH EXAMPLES
-.LP
-This example converts a baseline JPEG file to progressive form:
-.IP
-.B jpegtran \-progressive
-.I foo.jpg
-.B >
-.I fooprog.jpg
-.PP
-This example rotates an image 90 degrees clockwise, discarding any
-unrotatable edge pixels:
-.IP
-.B jpegtran \-rot 90 -trim
-.I foo.jpg
-.B >
-.I foo90.jpg
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-.SH NAME
-rdjpgcom \- display text comments from a JPEG file
-.SH SYNOPSIS
-.B rdjpgcom
-[
-.B \-raw
-]
-[
-.B \-verbose
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B rdjpgcom
-reads the named JPEG/JFIF file, or the standard input if no file is named,
-and prints any text comments found in the file on the standard output.
-.PP
-The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.
-Although the standard doesn't actually define what COM blocks are for, they
-are widely used to hold user-supplied text strings.  This lets you add
-annotations, titles, index terms, etc to your JPEG files, and later retrieve
-them as text.  COM blocks do not interfere with the image stored in the JPEG
-file.  The maximum size of a COM block is 64K, but you can have as many of
-them as you like in one JPEG file.
-.SH OPTIONS
-.TP
-.B \-raw
-Normally
-.B rdjpgcom
-escapes non-printable characters in comments, for security reasons.
-This option avoids that.
-.PP
-.B \-verbose
-Causes
-.B rdjpgcom
-to also display the JPEG image dimensions.
-.PP
-Switch names may be abbreviated, and are not case sensitive.
-.SH HINTS
-.B rdjpgcom
-does not depend on the IJG JPEG library.  Its source code is intended as an
-illustration of the minimum amount of code required to parse a JPEG file
-header correctly.
-.PP
-In
-.B \-verbose
-mode,
-.B rdjpgcom
-will also attempt to print the contents of any "APP12" markers as text.
-Some digital cameras produce APP12 markers containing useful textual
-information.  If you like, you can modify the source code to print
-other APPn marker types as well.

-# NOTE: The combination of tjEncodeYUV*() and tjCompressFromYUV*() does not
-# always produce bitwise-identical results to tjCompress*() if subsampling is
-# enabled.  In both cases, if the image width or height are not evenly
-# divisible by the MCU width/height, then the bottom and/or right edge are
-# expanded.  However, the libjpeg code performs this expansion prior to
-# downsampling, and TurboJPEG performs it in tjCompressFromYUV*(), which is
-# after downsampling.  Thus, the two will agree only if the width/height along
-# each downsampled dimension is an odd number or is evenly divisible by the MCU
-# width/height.  This disagreement basically amounts to a round-off error, but
-# there is no easy way around it, so for now, we just test the only image that
-# works.  (NOTE: nightshot_iso_100 does not suffer from the above issue, but
-# it suffers from an unrelated problem whereby the combination of
-# tjDecompressToYUV*() and tjDecodeYUV*() do not produce bitwise-identical
-# results to tjDecompress*() if decompression scaling is enabled.  This latter
-# phenomenon is not yet fully understood but is also believed to be some sort

-# NOTE: The combination of tjEncodeYUV*() and tjCompressFromYUV*() does not
-# always produce bitwise-identical results to tjCompress*() if subsampling is
-# enabled.  In both cases, if the image width or height are not evenly
-# divisible by the MCU width/height, then the bottom and/or right edge are
-# expanded.  However, the libjpeg code performs this expansion prior to
-# downsampling, and TurboJPEG performs it in tjCompressFromYUV*(), which is
-# after downsampling.  Thus, the two will agree only if the width/height along
-# each downsampled dimension is an odd number or is evenly divisible by the MCU
-# width/height.  This disagreement basically amounts to a round-off error, but
-# there is no easy way around it, so for now, we just test the only image that
-# works.  (NOTE: nightshot_iso_100 does not suffer from the above issue, but
-# it suffers from an unrelated problem whereby the combination of
-# tjDecompressToYUV*() and tjDecodeYUV*() do not produce bitwise-identical
-# results to tjDecompress*() if decompression scaling is enabled.  This latter
-# phenomenon is not yet fully understood but is also believed to be some sort
-# of round-off error.)

-.TH WRJPGCOM 1 "15 June 1995"
-.SH NAME
-wrjpgcom \- insert text comments into a JPEG file
-.SH SYNOPSIS
-.B wrjpgcom
-[
-.B \-replace
-]
-[
-.BI \-comment " text"
-]
-[
-.BI \-cfile " name"
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B wrjpgcom
-reads the named JPEG/JFIF file, or the standard input if no file is named,
-and generates a new JPEG/JFIF file on standard output.  A comment block is
-added to the file.
-.PP
-The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.
-Although the standard doesn't actually define what COM blocks are for, they
-are widely used to hold user-supplied text strings.  This lets you add
-annotations, titles, index terms, etc to your JPEG files, and later retrieve
-them as text.  COM blocks do not interfere with the image stored in the JPEG
-file.  The maximum size of a COM block is 64K, but you can have as many of
-them as you like in one JPEG file.
-.PP
-.B wrjpgcom
-adds a COM block, containing text you provide, to a JPEG file.
-Ordinarily, the COM block is added after any existing COM blocks; but you
-can delete the old COM blocks if you wish.
-.SH OPTIONS
-Switch names may be abbreviated, and are not case sensitive.
-.TP
-.B \-replace
-Delete any existing COM blocks from the file.
-.TP
-.BI \-comment " text"
-Supply text for new COM block on command line.
-.TP
-.BI \-cfile " name"
-Read text for new COM block from named file.
-.PP
-If you have only one line of comment text to add, you can provide it on the
-command line with
-.BR \-comment .
-The comment text must be surrounded with quotes so that it is treated as a
-single argument.  Longer comments can be read from a text file.
-.PP
-If you give neither
-.B \-comment
-nor
-.BR \-cfile,
-then
-.B wrjpgcom
-will read the comment text from standard input.  (In this case an input image
-file name MUST be supplied, so that the source JPEG file comes from somewhere
-else.)  You can enter multiple lines, up to 64KB worth.  Type an end-of-file
-indicator (usually control-D) to terminate the comment text entry.
-.PP
-.B wrjpgcom
-will not add a COM block if the provided comment string is empty.  Therefore
-\fB\-replace \-comment ""\fR can be used to delete all COM blocks from a file.
-.SH EXAMPLES
-.LP
-Add a short comment to in.jpg, producing out.jpg:
-.IP
-.B wrjpgcom \-c
-\fI"View of my back yard" in.jpg
-.B >
-.I out.jpg
-.PP
-Attach a long comment previously stored in comment.txt:
-.IP
-.B wrjpgcom
-.I in.jpg
-.B <
-.I comment.txt
-.B >
-.I out.jpg
-.PP
-or equivalently
-.IP
-.B wrjpgcom
-.B -cfile
-.I comment.txt
-.B <
-.I in.jpg
-.B >
-.I out.jpg

-
-
-OVERVIEW
-========
-
-This package contains C software to implement JPEG image compression and
-decompression.  JPEG (pronounced "jay-peg") is a standardized compression
-method for full-color and gray-scale images.  JPEG is intended for compressing
-"real-world" scenes; line drawings, cartoons and other non-realistic images
-are not its strong suit.  JPEG is lossy, meaning that the output image is not
-exactly identical to the input image.  Hence you must not use JPEG if you
-have to have identical output bits.  However, on typical photographic images,
-very good compression levels can be obtained with no visible change, and
-remarkably high compression levels are possible if you can tolerate a
-low-quality image.  For more details, see the references, or just experiment
-with various compression settings.
-
-This software implements JPEG baseline, extended-sequential, and progressive
-compression processes.  Provision is made for supporting all variants of these
-processes, although some uncommon parameter settings aren't implemented yet.
-For legal reasons, we are not distributing code for the arithmetic-coding
-variants of JPEG; see LEGAL ISSUES.  We have made no provision for supporting
-the hierarchical or lossless processes defined in the standard.
-
-We provide a set of library routines for reading and writing JPEG image files,
-plus two sample applications "cjpeg" and "djpeg", which use the library to
-perform conversion between JPEG and some other popular image file formats.
-The library is intended to be reused in other applications.
-
-In order to support file conversion and viewing software, we have included
-considerable functionality beyond the bare JPEG coding/decoding capability;
-for example, the color quantization modules are not strictly part of JPEG
-decoding, but they are essential for output to colormapped file formats or
-colormapped displays.  These extra functions can be compiled out of the
-library if not required for a particular application.  We have also included
-"jpegtran", a utility for lossless transcoding between different JPEG
-processes, and "rdjpgcom" and "wrjpgcom", two simple applications for
-inserting and extracting textual comments in JFIF files.
-
-The emphasis in designing this software has been on achieving portability and
-flexibility, while also making it fast enough to be useful.  In particular,
-the software is not intended to be read as a tutorial on JPEG.  (See the
-REFERENCES section for introductory material.)  Rather, it is intended to
-be reliable, portable, industrial-strength code.  We do not claim to have
-achieved that goal in every aspect of the software, but we strive for it.
-
-We welcome the use of this software as a component of commercial products.
-No royalty is required, but we do ask for an acknowledgement in product
-documentation, as described under LEGAL ISSUES.
-

-
-REFERENCES
-==========
-
-We highly recommend reading one or more of these references before trying to
-understand the innards of the JPEG software.
-
-The best short technical introduction to the JPEG compression algorithm is
-	Wallace, Gregory K.  "The JPEG Still Picture Compression Standard",
-	Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.
-(Adjacent articles in that issue discuss MPEG motion picture compression,
-applications of JPEG, and related topics.)  If you don't have the CACM issue
-handy, a PostScript file containing a revised version of Wallace's article is
-available at ftp://ftp.uu.net/graphics/jpeg/wallace.ps.gz.  The file (actually
-a preprint for an article that appeared in IEEE Trans. Consumer Electronics)
-omits the sample images that appeared in CACM, but it includes corrections
-and some added material.  Note: the Wallace article is copyright ACM and IEEE,
-and it may not be used for commercial purposes.
-
-A somewhat less technical, more leisurely introduction to JPEG can be found in
-"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by
-M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1.  This book provides
-good explanations and example C code for a multitude of compression methods
-including JPEG.  It is an excellent source if you are comfortable reading C
-code but don't know much about data compression in general.  The book's JPEG
-sample code is far from industrial-strength, but when you are ready to look
-at a full implementation, you've got one here...
-
-The best full description of JPEG is the textbook "JPEG Still Image Data
-Compression Standard" by William B. Pennebaker and Joan L. Mitchell, published
-by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1.  Price US$59.95, 638 pp.
-The book includes the complete text of the ISO JPEG standards (DIS 10918-1
-and draft DIS 10918-2).  This is by far the most complete exposition of JPEG
-in existence, and we highly recommend it.
-
-The JPEG standard itself is not available electronically; you must order a
-paper copy through ISO or ITU.  (Unless you feel a need to own a certified
-official copy, we recommend buying the Pennebaker and Mitchell book instead;
-it's much cheaper and includes a great deal of useful explanatory material.)
-In the USA, copies of the standard may be ordered from ANSI Sales at (212)
-642-4900, or from Global Engineering Documents at (800) 854-7179.  (ANSI
-doesn't take credit card orders, but Global does.)  It's not cheap: as of
-1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus 7%
-shipping/handling.  The standard is divided into two parts, Part 1 being the
-actual specification, while Part 2 covers compliance testing methods.  Part 1
-is titled "Digital Compression and Coding of Continuous-tone Still Images,
-Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS
-10918-1, ITU-T T.81.  Part 2 is titled "Digital Compression and Coding of
-Continuous-tone Still Images, Part 2: Compliance testing" and has document
-numbers ISO/IEC IS 10918-2, ITU-T T.83.
-
-Some extensions to the original JPEG standard are defined in JPEG Part 3,
-a newer ISO standard numbered ISO/IEC IS 10918-3 and ITU-T T.84.  IJG
-currently does not support any Part 3 extensions.
-
-The JPEG standard does not specify all details of an interchangeable file
-format.  For the omitted details we follow the "JFIF" conventions, revision
-1.02.  A copy of the JFIF spec is available from:
-	Literature Department
-	C-Cube Microsystems, Inc.
-	1778 McCarthy Blvd.
-	Milpitas, CA 95035
-	phone (408) 944-6300,  fax (408) 944-6314
-A PostScript version of this document is available by FTP at
-ftp://ftp.uu.net/graphics/jpeg/jfif.ps.gz.  There is also a plain text
-version at ftp://ftp.uu.net/graphics/jpeg/jfif.txt.gz, but it is missing
-the figures.
-
-The TIFF 6.0 file format specification can be obtained by FTP from
-ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz.  The JPEG incorporation scheme
-found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems.
-IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6).
-Instead, we recommend the JPEG design proposed by TIFF Technical Note #2
-(Compression tag 7).  Copies of this Note can be obtained from ftp.sgi.com or
-from ftp://ftp.uu.net/graphics/jpeg/.  It is expected that the next revision
-of the TIFF spec will replace the 6.0 JPEG design with the Note's design.
-Although IJG's own code does not support TIFF/JPEG, the free libtiff library
-uses our library to implement TIFF/JPEG per the Note.  libtiff is available
-from ftp://ftp.sgi.com/graphics/tiff/.
-
-
-ARCHIVE LOCATIONS
-=================
-
-The "official" archive site for this software is ftp.uu.net (Internet
-address 192.48.96.9).  The most recent released version can always be found
-there in directory graphics/jpeg.  This particular version will be archived
-as ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz.  If you don't have
-direct Internet access, UUNET's archives are also available via UUCP; contact
-help@uunet.uu.net for information on retrieving files that way.
-
-Numerous Internet sites maintain copies of the UUNET files.  However, only
-ftp.uu.net is guaranteed to have the latest official version.
-
-You can also obtain this software in DOS-compatible "zip" archive format from
-the SimTel archives (ftp://ftp.simtel.net/pub/simtelnet/msdos/graphics/), or
-on CompuServe in the Graphics Support forum (GO CIS:GRAPHSUP), library 12
-"JPEG Tools".  Again, these versions may sometimes lag behind the ftp.uu.net
-release.
-
-The JPEG FAQ (Frequently Asked Questions) article is a useful source of
-general information about JPEG.  It is updated constantly and therefore is
-not included in this distribution.  The FAQ is posted every two weeks to
-Usenet newsgroups comp.graphics.misc, news.answers, and other groups.
-It is available on the World Wide Web at http://www.faqs.org/faqs/jpeg-faq/
-and other news.answers archive sites, including the official news.answers
-archive at rtfm.mit.edu: ftp://rtfm.mit.edu/pub/usenet/news.answers/jpeg-faq/.
-If you don't have Web or FTP access, send e-mail to mail-server@rtfm.mit.edu

-RELATED SOFTWARE
-================
-
-Numerous viewing and image manipulation programs now support JPEG.  (Quite a
-few of them use this library to do so.)  The JPEG FAQ described above lists
-some of the more popular free and shareware viewers, and tells where to
-obtain them on Internet.
-
-If you are on a Unix machine, we highly recommend Jef Poskanzer's free
-PBMPLUS software, which provides many useful operations on PPM-format image
-files.  In particular, it can convert PPM images to and from a wide range of
-other formats, thus making cjpeg/djpeg considerably more useful.  The latest
-version is distributed by the NetPBM group, and is available from numerous
-sites, notably ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/.
-Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software is;
-you are likely to have difficulty making it work on any non-Unix machine.
-
-A different free JPEG implementation, written by the PVRG group at Stanford,
-is available from ftp://havefun.stanford.edu/pub/jpeg/.  This program
-is designed for research and experimentation rather than production use;
-it is slower, harder to use, and less portable than the IJG code, but it
-is easier to read and modify.  Also, the PVRG code supports lossless JPEG,
-which we do not.  (On the other hand, it doesn't do progressive JPEG.)
-
-
-FILE FORMAT WARS
-================
-
-Some JPEG programs produce files that are not compatible with our library.
-The root of the problem is that the ISO JPEG committee failed to specify a
-concrete file format.  Some vendors "filled in the blanks" on their own,
-creating proprietary formats that no one else could read.  (For example, none
-of the early commercial JPEG implementations for the Macintosh were able to
-exchange compressed files.)
-
-The file format we have adopted is called JFIF (see REFERENCES).  This format
-has been agreed to by a number of major commercial JPEG vendors, and it has
-become the de facto standard.  JFIF is a minimal or "low end" representation.
-We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF
-Technical Note #2) for "high end" applications that need to record a lot of
-additional data about an image.  TIFF/JPEG is fairly new and not yet widely
-supported, unfortunately.
-
-The upcoming JPEG Part 3 standard defines a file format called SPIFF.
-SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should
-be able to read the most common variant of SPIFF.  SPIFF has some technical
-advantages over JFIF, but its major claim to fame is simply that it is an
-official standard rather than an informal one.  At this point it is unclear
-whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto
-standard.  IJG intends to support SPIFF once the standard is frozen, but we
-have not decided whether it should become our default output format or not.
-(In any case, our decoder will remain capable of reading JFIF indefinitely.)
-
-Various proprietary file formats incorporating JPEG compression also exist.
-We have little or no sympathy for the existence of these formats.  Indeed,
-one of the original reasons for developing this free software was to help
-force convergence on common, open format standards for JPEG files.  Don't
-use a proprietary file format!
-
-
-TO DO
-=====
-
-The major thrust for v7 will probably be improvement of visual quality.
-The current method for scaling the quantization tables is known not to be
-very good at low Q values.  We also intend to investigate block boundary
-smoothing, "poor man's variable quantization", and other means of improving
-quality-vs-file-size performance without sacrificing compatibility.
-
-In future versions, we are considering supporting some of the upcoming JPEG
-Part 3 extensions --- principally, variable quantization and the SPIFF file
-format.
-
-As always, speeding things up is of great interest.
-
-Please send bug reports, offers of help, etc. to jpeg-info@uunet.uu.net.

-
-/*
- * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
- * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * The conversion equations to be implemented are therefore
- *	Y  =  0.29900 * R + 0.58700 * G + 0.11400 * B
- *	Cb = -0.16874 * R - 0.33126 * G + 0.50000 * B  + CENTERJSAMPLE
- *	Cr =  0.50000 * R - 0.41869 * G - 0.08131 * B  + CENTERJSAMPLE
- * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
- * Note: older versions of the IJG code used a zero offset of MAXJSAMPLE/2,
- * rather than CENTERJSAMPLE, for Cb and Cr.  This gave equal positive and
- * negative swings for Cb/Cr, but meant that grayscale values (Cb=Cr=0)
- * were not represented exactly.  Now we sacrifice exact representation of
- * maximum red and maximum blue in order to get exact grayscales.
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
- * the products by 2^16, with appropriate rounding, to get the correct answer.
- *
- * For even more speed, we avoid doing any multiplications in the inner loop
- * by precalculating the constants times R,G,B for all possible values.
- * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
- * for 12-bit samples it is still acceptable.  It's not very reasonable for
- * 16-bit samples, but if you want lossless storage you shouldn't be changing
- * colorspace anyway.
- * The CENTERJSAMPLE offsets and the rounding fudge-factor of 0.5 are included
- * in the tables to save adding them separately in the inner loop.

- * can't look like a valid code).  Because of the canonical ordering of
- * codewords, this just means that there must be an unused slot in the
- * longest codeword length category.  Section K.2 of the JPEG spec suggests
- * reserving such a slot by pretending that symbol 256 is a valid symbol
- * with count 1.  In theory that's not optimal; giving it count zero but
- * including it in the symbol set anyway should give a better Huffman code.
- * But the theoretically better code actually seems to come out worse in
- * practice, because it produces more all-ones bytes (which incur stuffed
- * zero bytes in the final file).  In any case the difference is tiny.
- *
- * The JPEG standard requires Huffman codes to be no more than 16 bits long.
- * If some symbols have a very small but nonzero probability, the Huffman tree
- * must be adjusted to meet the code length restriction.  We currently use
- * the adjustment method suggested in JPEG section K.2.  This method is *not*
- * optimal; it may not choose the best possible limited-length code.  But
- * typically only very-low-frequency symbols will be given less-than-optimal
- * lengths, so the code is almost optimal.  Experimental comparisons against
- * an optimal limited-length-code algorithm indicate that the difference is
- * microscopic --- usually less than a hundredth of a percent of total size.

- * jcsample.c
- *
- * Copyright (C) 1991-1996, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains downsampling routines.
- *
- * Downsampling input data is counted in "row groups".  A row group
- * is defined to be max_v_samp_factor pixel rows of each component,
- * from which the downsampler produces v_samp_factor sample rows.
- * A single row group is processed in each call to the downsampler module.
- *
- * The downsampler is responsible for edge-expansion of its output data
- * to fill an integral number of DCT blocks horizontally.  The source buffer
- * may be modified if it is helpful for this purpose (the source buffer is
- * allocated wide enough to correspond to the desired output width).
- * The caller (the prep controller) is responsible for vertical padding.
- *
- * The downsampler may request "context rows" by setting need_context_rows
- * during startup.  In this case, the input arrays will contain at least
- * one row group's worth of pixels above and below the passed-in data;
- * the caller will create dummy rows at image top and bottom by replicating
- * the first or last real pixel row.
- *
- * An excellent reference for image resampling is
- *   Digital Image Warping, George Wolberg, 1990.
- *   Pub. by IEEE Computer Society Press, Los Alamitos, CA. ISBN 0-8186-8944-7.
- *
- * The downsampling algorithm used here is a simple average of the source
- * pixels covered by the output pixel.  The hi-falutin sampling literature
- * refers to this as a "box filter".  In general the characteristics of a box
- * filter are not very good, but for the specific cases we normally use (1:1
- * and 2:1 ratios) the box is equivalent to a "triangle filter" which is not
- * nearly so bad.  If you intend to use other sampling ratios, you'd be well
- * advised to improve this code.
- *
- * A simple input-smoothing capability is provided.  This is mainly intended
- * for cleaning up color-dithered GIF input files (if you find it inadequate,
- * we suggest using an external filtering program such as pnmconvol).  When
- * enabled, each input pixel P is replaced by a weighted sum of itself and its
- * eight neighbors.  P's weight is 1-8*SF and each neighbor's weight is SF,
- * where SF = (smoothing_factor / 1024).
- * Currently, smoothing is only supported for 2h2v sampling factors.

-
-/*
- * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
- * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * The conversion equations to be implemented are therefore
- *	R = Y                + 1.40200 * Cr
- *	G = Y - 0.34414 * Cb - 0.71414 * Cr
- *	B = Y + 1.77200 * Cb
- * where Cb and Cr represent the incoming values less CENTERJSAMPLE.
- * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
- * the products by 2^16, with appropriate rounding, to get the correct answer.
- * Notice that Y, being an integral input, does not contribute any fraction
- * so it need not participate in the rounding.
- *
- * For even more speed, we avoid doing any multiplications in the inner loop
- * by precalculating the constants times Cb and Cr for all possible values.
- * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
- * for 12-bit samples it is still acceptable.  It's not very reasonable for
- * 16-bit samples, but if you want lossless storage you shouldn't be changing
- * colorspace anyway.
- * The Cr=>R and Cb=>B values can be rounded to integers in advance; the
- * values for the G calculation are left scaled up, since we must add them
- * together before rounding.

- * to one row of MCUs when the image is fully interleaved.)  Note that the
- * number of sample rows varies across components, but the number of row
- * groups does not.  Some garbage sample rows may be included in the last iMCU
- * row at the bottom of the image.
- *
- * Depending on the vertical scaling algorithm used, the upsampler may need
- * access to the sample row(s) above and below its current input row group.
- * The upsampler is required to set need_context_rows TRUE at global selection
- * time if so.  When need_context_rows is FALSE, this controller can simply
- * obtain one iMCU row at a time from the coefficient controller and dole it
- * out as row groups to the postprocessor.
- *
- * When need_context_rows is TRUE, this controller guarantees that the buffer
- * passed to postprocessing contains at least one row group's worth of samples
- * above and below the row group(s) being processed.  Note that the context
- * rows "above" the first passed row group appear at negative row offsets in
- * the passed buffer.  At the top and bottom of the image, the required
- * context rows are manufactured by duplicating the first or last real sample
- * row; this avoids having special cases in the upsampling inner loops.
- *
- * The amount of context is fixed at one row group just because that's a
- * convenient number for this controller to work with.  The existing
- * upsamplers really only need one sample row of context.  An upsampler
- * supporting arbitrary output rescaling might wish for more than one row
- * group of context when shrinking the image; tough, we don't handle that.
- * (This is justified by the assumption that downsizing will be handled mostly
- * by adjusting the DCT_scaled_size values, so that the actual scale factor at
- * the upsample step needn't be much less than one.)
- *
- * To provide the desired context, we have to retain the last two row groups
- * of one iMCU row while reading in the next iMCU row.  (The last row group
- * can't be processed until we have another row group for its below-context,
- * and so we have to save the next-to-last group too for its above-context.)
- * We could do this most simply by copying data around in our buffer, but
- * that'd be very slow.  We can avoid copying any data by creating a rather
- * strange pointer structure.  Here's how it works.  We allocate a workspace
- * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number
- * of row groups per iMCU row).  We create two sets of redundant pointers to
- * the workspace.  Labeling the physical row groups 0 to M+1, the synthesized
- * pointer lists look like this:
- *                   M+1                          M-1
- * master pointer --> 0         master pointer --> 0
- *                    1                            1
- *                   ...                          ...
- *                   M-3                          M-3
- *                   M-2                           M
- *                   M-1                          M+1
- *                    M                           M-2
- *                   M+1                          M-1
- *                    0                            0
- * We read alternate iMCU rows using each master pointer; thus the last two
- * row groups of the previous iMCU row remain un-overwritten in the workspace.
- * The pointer lists are set up so that the required context rows appear to
- * be adjacent to the proper places when we pass the pointer lists to the
- * upsampler.
- *
- * The above pictures describe the normal state of the pointer lists.
- * At top and bottom of the image, we diddle the pointer lists to duplicate
- * the first or last sample row as necessary (this is cheaper than copying
- * sample rows around).
- *
- * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1.  In that
- * situation each iMCU row provides only one row group so the buffering logic
- * must be different (eg, we must read two iMCU rows before we can emit the
- * first row group).  For now, we simply do not support providing context
- * rows when min_DCT_scaled_size is 1.  That combination seems unlikely to
- * be worth providing --- if someone wants a 1/8th-size preview, they probably
- * want it quick and dirty, so a context-free upsampler is sufficient.

- *
- * This approach to suspension assumes that all of a marker's parameters
- * can fit into a single input bufferload.  This should hold for "normal"
- * markers.  Some COM/APPn markers might have large parameter segments
- * that might not fit.  If we are simply dropping such a marker, we use

- * source manager's shoulders.  If we are saving the marker's contents
- * into memory, we use a slightly different convention: when forced to
- * suspend, the marker processor updates the restart point to the end of
- * what it's consumed (ie, the end of the buffer) before returning FALSE.
- * On resumption, cinfo->unread_marker still contains the marker code,
- * but the data source will point to the next chunk of marker data.
- * The marker processor must retain internal state to deal with this.
- *
- * Note that we don't bother to avoid duplicate trace messages if a
- * suspension occurs within marker parameters.  Other side effects

- *
- * read_restart_marker calls resync_to_restart if it finds a marker other than
- * the restart marker it was expecting.  (This code is *not* used unless
- * a nonzero restart interval has been declared.)  cinfo->unread_marker is
- * the marker code actually found (might be anything, except 0 or FF).
- * The desired restart marker number (0..7) is passed as a parameter.
- * This routine is supposed to apply whatever error recovery strategy seems
- * appropriate in order to position the input stream to the next data segment.
- * Note that cinfo->unread_marker is treated as a marker appearing before
- * the current data-source input point; usually it should be reset to zero
- * before returning.
- * Returns FALSE if suspension is required.
- *
- * This implementation is substantially constrained by wanting to treat the
- * input as a data stream; this means we can't back up.  Therefore, we have
- * only the following actions to work with:
- *   1. Simply discard the marker and let the entropy decoder resume at next
- *      byte of file.
- *   2. Read forward until we find another marker, discarding intervening
- *      data.  (In theory we could look ahead within the current bufferload,
- *      without having to discard data if we don't find the desired marker.
- *      This idea is not implemented here, in part because it makes behavior
- *      dependent on buffer size and chance buffer-boundary positions.)
- *   3. Leave the marker unread (by failing to zero cinfo->unread_marker).
- *      This will cause the entropy decoder to process an empty data segment,
- *      inserting dummy zeroes, and then we will reprocess the marker.
- *
- * #2 is appropriate if we think the desired marker lies ahead, while #3 is
- * appropriate if the found marker is a future restart marker (indicating
- * that we have missed the desired restart marker, probably because it got
- * corrupted).
- * We apply #2 or #3 if the found marker is a restart marker no more than
- * two counts behind or ahead of the expected one.  We also apply #2 if the
- * found marker is not a legal JPEG marker code (it's certainly bogus data).
- * If the found marker is a restart marker more than 2 counts away, we do #1
- * (too much risk that the marker is erroneous; with luck we will be able to
- * resync at some future point).
- * For any valid non-restart JPEG marker, we apply #3.  This keeps us from
- * overrunning the end of a scan.  An implementation limited to single-scan
- * files might find it better to apply #2 for markers other than EOI, since
- * any other marker would have to be bogus data in that case.

- * Several decompression processes need to range-limit values to the range
- * 0..MAXJSAMPLE; the input value may fall somewhat outside this range
- * due to noise introduced by quantization, roundoff error, etc.  These
- * processes are inner loops and need to be as fast as possible.  On most
- * machines, particularly CPUs with pipelines or instruction prefetch,
- * a (subscript-check-less) C table lookup
- *		x = sample_range_limit[x];
- * is faster than explicit tests
- *		if (x < 0)  x = 0;
- *		else if (x > MAXJSAMPLE)  x = MAXJSAMPLE;
- * These processes all use a common table prepared by the routine below.
- *
- * For most steps we can mathematically guarantee that the initial value
- * of x is within MAXJSAMPLE+1 of the legal range, so a table running from
- * -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient.  But for the initial
- * limiting step (just after the IDCT), a wildly out-of-range value is 
- * possible if the input data is corrupt.  To avoid any chance of indexing
- * off the end of memory and getting a bad-pointer trap, we perform the
- * post-IDCT limiting thus:
- *		x = range_limit[x & MASK];
- * where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit
- * samples.  Under normal circumstances this is more than enough range and
- * a correct output will be generated; with bogus input data the mask will
- * cause wraparound, and we will safely generate a bogus-but-in-range output.
- * For the post-IDCT step, we want to convert the data from signed to unsigned
- * representation by adding CENTERJSAMPLE at the same time that we limit it.
- * So the post-IDCT limiting table ends up looking like this:
- *   CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,
- *   MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
- *   0          (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
- *   0,1,...,CENTERJSAMPLE-1
- * Negative inputs select values from the upper half of the table after
- * masking.
- *
- * We can save some space by overlapping the start of the post-IDCT table
- * with the simpler range limiting table.  The post-IDCT table begins at
- * sample_range_limit + CENTERJSAMPLE.
- *
- * Note that the table is allocated in near data space on PCs; it's small
- * enough and used often enough to justify this.

- * This file is part of the Independent JPEG Group's software.

- *
- * This file contains code for merged upsampling/color conversion.
- *
- * This file combines functions from jdsample.c and jdcolor.c;
- * read those files first to understand what's going on.
- *
- * When the chroma components are to be upsampled by simple replication
- * (ie, box filtering), we can save some work in color conversion by
- * calculating all the output pixels corresponding to a pair of chroma
- * samples at one time.  In the conversion equations
- *	R = Y           + K1 * Cr
- *	G = Y + K2 * Cb + K3 * Cr
- *	B = Y + K4 * Cb
- * only the Y term varies among the group of pixels corresponding to a pair
- * of chroma samples, so the rest of the terms can be calculated just once.
- * At typical sampling ratios, this eliminates half or three-quarters of the
- * multiplications needed for color conversion.
- *
- * This file currently provides implementations for the following cases:
- *	YCbCr => RGB color conversion only.
- *	Sampling ratios of 2h1v or 2h2v.
- *	No scaling needed at upsample time.
- *	Corner-aligned (non-CCIR601) sampling alignment.
- * Other special cases could be added, but in most applications these are
- * the only common cases.  (For uncommon cases we fall back on the more
- * general code in jdsample.c and jdcolor.c.)

- * This file contains a floating-point implementation of the
- * forward DCT (Discrete Cosine Transform).
- *
- * This implementation should be more accurate than either of the integer
- * DCT implementations.  However, it may not give the same results on all
- * machines because of differences in roundoff behavior.  Speed will depend
- * on the hardware's floating point capacity.
- *
- * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
- * on each column.  Direct algorithms are also available, but they are
- * much more complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on Arai, Agui, and Nakajima's algorithm for
- * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
- * Japanese, but the algorithm is described in the Pennebaker & Mitchell
- * JPEG textbook (see REFERENCES section in file README).  The following code
- * is based directly on figure 4-8 in P&M.
- * While an 8-point DCT cannot be done in less than 11 multiplies, it is
- * possible to arrange the computation so that many of the multiplies are
- * simple scalings of the final outputs.  These multiplies can then be
- * folded into the multiplications or divisions by the JPEG quantization
- * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
- * to be done in the DCT itself.
- * The primary disadvantage of this method is that with a fixed-point
- * implementation, accuracy is lost due to imprecise representation of the
- * scaled quantization values.  However, that problem does not arise if
- * we use floating point arithmetic.

- * This file contains a slow-but-accurate integer implementation of the
- * forward DCT (Discrete Cosine Transform).
- *
- * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
- * on each column.  Direct algorithms are also available, but they are
- * much more complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on an algorithm described in
- *   C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
- *   Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
- *   Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
- * The primary algorithm described there uses 11 multiplies and 29 adds.
- * We use their alternate method with 12 multiplies and 32 adds.
- * The advantage of this method is that no data path contains more than one
- * multiplication; this allows a very simple and accurate implementation in
- * scaled fixed-point arithmetic, with a minimal number of shifts.

- * The poop on this scaling stuff is as follows:
- *
- * Each 1-D DCT step produces outputs which are a factor of sqrt(N)
- * larger than the true DCT outputs.  The final outputs are therefore
- * a factor of N larger than desired; since N=8 this can be cured by
- * a simple right shift at the end of the algorithm.  The advantage of
- * this arrangement is that we save two multiplications per 1-D DCT,
- * because the y0 and y4 outputs need not be divided by sqrt(N).
- * In the IJG code, this factor of 8 is removed by the quantization step
- * (in jcdctmgr.c), NOT in this module.
- *
- * We have to do addition and subtraction of the integer inputs, which
- * is no problem, and multiplication by fractional constants, which is
- * a problem to do in integer arithmetic.  We multiply all the constants
- * by CONST_SCALE and convert them to integer constants (thus retaining
- * CONST_BITS bits of precision in the constants).  After doing a
- * multiplication we have to divide the product by CONST_SCALE, with proper
- * rounding, to produce the correct output.  This division can be done
- * cheaply as a right shift of CONST_BITS bits.  We postpone shifting
- * as long as possible so that partial sums can be added together with
- * full fractional precision.
- *
- * The outputs of the first pass are scaled up by PASS1_BITS bits so that
- * they are represented to better-than-integral precision.  These outputs
- * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
- * with the recommended scaling.  (For 12-bit sample data, the intermediate
- * array is INT32 anyway.)
- *
- * To avoid overflow of the 32-bit intermediate results in pass 2, we must
- * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26.  Error analysis
- * shows that the values given below are the most effective.

- * Copyright (C) 1994-1998, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a floating-point implementation of the
- * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
- * must also perform dequantization of the input coefficients.
- *
- * This implementation should be more accurate than either of the integer
- * IDCT implementations.  However, it may not give the same results on all
- * machines because of differences in roundoff behavior.  Speed will depend
- * on the hardware's floating point capacity.
- *
- * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
- * on each row (or vice versa, but it's more convenient to emit a row at
- * a time).  Direct algorithms are also available, but they are much more
- * complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on Arai, Agui, and Nakajima's algorithm for
- * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
- * Japanese, but the algorithm is described in the Pennebaker & Mitchell
- * JPEG textbook (see REFERENCES section in file README).  The following code
- * is based directly on figure 4-8 in P&M.
- * While an 8-point DCT cannot be done in less than 11 multiplies, it is
- * possible to arrange the computation so that many of the multiplies are
- * simple scalings of the final outputs.  These multiplies can then be
- * folded into the multiplications or divisions by the JPEG quantization
- * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
- * to be done in the DCT itself.
- * The primary disadvantage of this method is that with a fixed-point
- * implementation, accuracy is lost due to imprecise representation of the
- * scaled quantization values.  However, that problem does not arise if
- * we use floating point arithmetic.

- * jidctint.c
- *
- * Copyright (C) 1991-1998, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a slow-but-accurate integer implementation of the
- * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
- * must also perform dequantization of the input coefficients.
- *
- * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
- * on each row (or vice versa, but it's more convenient to emit a row at
- * a time).  Direct algorithms are also available, but they are much more
- * complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on an algorithm described in
- *   C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
- *   Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
- *   Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
- * The primary algorithm described there uses 11 multiplies and 29 adds.
- * We use their alternate method with 12 multiplies and 32 adds.
- * The advantage of this method is that no data path contains more than one
- * multiplication; this allows a very simple and accurate implementation in
- * scaled fixed-point arithmetic, with a minimal number of shifts.

- * The poop on this scaling stuff is as follows:
- *
- * Each 1-D IDCT step produces outputs which are a factor of sqrt(N)
- * larger than the true IDCT outputs.  The final outputs are therefore
- * a factor of N larger than desired; since N=8 this can be cured by
- * a simple right shift at the end of the algorithm.  The advantage of
- * this arrangement is that we save two multiplications per 1-D IDCT,
- * because the y0 and y4 inputs need not be divided by sqrt(N).
- *
- * We have to do addition and subtraction of the integer inputs, which
- * is no problem, and multiplication by fractional constants, which is
- * a problem to do in integer arithmetic.  We multiply all the constants
- * by CONST_SCALE and convert them to integer constants (thus retaining
- * CONST_BITS bits of precision in the constants).  After doing a
- * multiplication we have to divide the product by CONST_SCALE, with proper
- * rounding, to produce the correct output.  This division can be done
- * cheaply as a right shift of CONST_BITS bits.  We postpone shifting
- * as long as possible so that partial sums can be added together with
- * full fractional precision.
- *
- * The outputs of the first pass are scaled up by PASS1_BITS bits so that
- * they are represented to better-than-integral precision.  These outputs
- * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
- * with the recommended scaling.  (To scale up 12-bit sample data further, an
- * intermediate INT32 array would be needed.)
- *
- * To avoid overflow of the 32-bit intermediate results in pass 2, we must
- * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26.  Error analysis
- * shows that the values given below are the most effective.

- * Copyright (C) 1994-1998, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains inverse-DCT routines that produce reduced-size output:
- * either 4x4, 2x2, or 1x1 pixels from an 8x8 DCT block.
- *
- * The implementation is based on the Loeffler, Ligtenberg and Moschytz (LL&M)
- * algorithm used in jidctint.c.  We simply replace each 8-to-8 1-D IDCT step
- * with an 8-to-4 step that produces the four averages of two adjacent outputs
- * (or an 8-to-2 step producing two averages of four outputs, for 2x2 output).
- * These steps were derived by computing the corresponding values at the end
- * of the normal LL&M code, then simplifying as much as possible.
- *
- * 1x1 is trivial: just take the DC coefficient divided by 8.
- *
- * See jidctint.c for additional comments.

- * About virtual array management:
- *
- * The above "normal" array routines are only used to allocate strip buffers
- * (as wide as the image, but just a few rows high).  Full-image-sized buffers
- * are handled as "virtual" arrays.  The array is still accessed a strip at a
- * time, but the memory manager must save the whole array for repeated
- * accesses.  The intended implementation is that there is a strip buffer in
- * memory (as high as is possible given the desired memory limit), plus a
- * backing file that holds the rest of the array.
- *
- * The request_virt_array routines are told the total size of the image and
- * the maximum number of rows that will be accessed at once.  The in-memory
- * buffer must be at least as large as the maxaccess value.
- *
- * The request routines create control blocks but not the in-memory buffers.
- * That is postponed until realize_virt_arrays is called.  At that time the
- * total amount of space needed is known (approximately, anyway), so free
- * memory can be divided up fairly.
- *
- * The access_virt_array routines are responsible for making a specific strip
- * area accessible (after reading or writing the backing file, if necessary).
- * Note that the access routines are told whether the caller intends to modify
- * the accessed strip; during a read-only pass this saves having to rewrite
- * data to disk.  The access routines are also responsible for pre-zeroing
- * any newly accessed rows, if pre-zeroing was requested.
- *
- * In current usage, the access requests are usually for nonoverlapping
- * strips; that is, successive access start_row numbers differ by exactly
- * num_rows = maxaccess.  This means we can get good performance with simple
- * buffer dump/reload logic, by making the in-memory buffer be a multiple
- * of the access height; then there will never be accesses across bufferload
- * boundaries.  The code will still work with overlapping access requests,
- * but it doesn't handle bufferload overlaps very efficiently.

-/*
- * The main purpose of 1-pass quantization is to provide a fast, if not very
- * high quality, colormapped output capability.  A 2-pass quantizer usually
- * gives better visual quality; however, for quantized grayscale output this
- * quantizer is perfectly adequate.  Dithering is highly recommended with this
- * quantizer, though you can turn it off if you really want to.
- *
- * In 1-pass quantization the colormap must be chosen in advance of seeing the
- * image.  We use a map consisting of all combinations of Ncolors[i] color
- * values for the i'th component.  The Ncolors[] values are chosen so that
- * their product, the total number of colors, is no more than that requested.
- * (In most cases, the product will be somewhat less.)
- *
- * Since the colormap is orthogonal, the representative value for each color
- * component can be determined without considering the other components;
- * then these indexes can be combined into a colormap index by a standard
- * N-dimensional-array-subscript calculation.  Most of the arithmetic involved
- * can be precalculated and stored in the lookup table colorindex[].
- * colorindex[i][j] maps pixel value j in component i to the nearest
- * representative value (grid plane) for that component; this index is
- * multiplied by the array stride for component i, so that the
- * index of the colormap entry closest to a given pixel value is just
- *    sum( colorindex[component-number][pixel-component-value] )
- * Aside from being fast, this scheme allows for variable spacing between
- * representative values with no additional lookup cost.
- *
- * If gamma correction has been applied in color conversion, it might be wise
- * to adjust the color grid spacing so that the representative colors are
- * equidistant in linear space.  At this writing, gamma correction is not
- * implemented by jdcolor, so nothing is done here.
- */

-
-/* Declarations for ordered dithering.
- *
- * We use a standard 16x16 ordered dither array.  The basic concept of ordered
- * dithering is described in many references, for instance Dale Schumacher's
- * chapter II.2 of Graphics Gems II (James Arvo, ed. Academic Press, 1991).
- * In place of Schumacher's comparisons against a "threshold" value, we add a
- * "dither" value to the input pixel and then round the result to the nearest
- * output value.  The dither value is equivalent to (0.5 - threshold) times
- * the distance between output values.  For ordered dithering, we assume that
- * the output colors are equally spaced; if not, results will probably be
- * worse, since the dither may be too much or too little at a given point.
- *
- * The normal calculation would be to form pixel value + dither, range-limit
- * this to 0..MAXJSAMPLE, and then index into the colorindex table as usual.
- * We can skip the separate range-limiting step by extending the colorindex
- * table in both directions.

- * This module implements the well-known Heckbert paradigm for color
- * quantization.  Most of the ideas used here can be traced back to
- * Heckbert's seminal paper
- *   Heckbert, Paul.  "Color Image Quantization for Frame Buffer Display",
- *   Proc. SIGGRAPH '82, Computer Graphics v.16 #3 (July 1982), pp 297-304.
- *
- * In the first pass over the image, we accumulate a histogram showing the
- * usage count of each possible color.  To keep the histogram to a reasonable
- * size, we reduce the precision of the input; typical practice is to retain
- * 5 or 6 bits per color, so that 8 or 4 different input values are counted
- * in the same histogram cell.
- *
- * Next, the color-selection step begins with a box representing the whole
- * color space, and repeatedly splits the "largest" remaining box until we
- * have as many boxes as desired colors.  Then the mean color in each
- * remaining box becomes one of the possible output colors.
- * 
- * The second pass over the image maps each input pixel to the closest output
- * color (optionally after applying a Floyd-Steinberg dithering correction).
- * This mapping is logically trivial, but making it go fast enough requires
- * considerable care.
- *
- * Heckbert-style quantizers vary a good deal in their policies for choosing
- * the "largest" box and deciding where to cut it.  The particular policies
- * used here have proved out well in experimental comparisons, but better ones
- * may yet be found.
- *
- * In earlier versions of the IJG code, this module quantized in YCbCr color
- * space, processing the raw upsampled data without a color conversion step.
- * This allowed the color conversion math to be done only once per colormap
- * entry, not once per pixel.  However, that optimization precluded other
- * useful optimizations (such as merging color conversion with upsampling)
- * and it also interfered with desired capabilities such as quantizing to an
- * externally-supplied colormap.  We have therefore abandoned that approach.
- * The present code works in the post-conversion color space, typically RGB.
- *
- * To improve the visual quality of the results, we actually work in scaled
- * RGB space, giving G distances more weight than R, and R in turn more than
- * B.  To do everything in integer math, we must use integer scale factors.
- * The 2/3/1 scale factors used here correspond loosely to the relative
- * weights of the colors in the NTSC grayscale equation.
- * If you want to use this code to quantize a non-RGB color space, you'll
- * probably need to change these scale factors.

- * and B,G,R orders.  If you define some other weird order in jmorecfg.h,
- * you'll get compile errors until you extend this logic.  In that case
- * you'll probably want to tweak the histogram sizes too.

- * First we have the histogram data structure and routines for creating it.
- *
- * The number of bits of precision can be adjusted by changing these symbols.
- * We recommend keeping 6 bits for G and 5 each for R and B.
- * If you have plenty of memory and cycles, 6 bits all around gives marginally
- * better results; if you are short of memory, 5 bits all around will save
- * some space but degrade the results.
- * To maintain a fully accurate histogram, we'd need to allocate a "long"
- * (preferably unsigned long) for each cell.  In practice this is overkill;
- * we can get by with 16 bits per cell.  Few of the cell counts will overflow,
- * and clamping those that do overflow to the maximum value will give close-
- * enough results.  This reduces the recommended histogram size from 256Kb
- * to 128Kb, which is a useful savings on PC-class machines.
- * (In the second pass the histogram space is re-used for pixel mapping data;
- * in that capacity, each cell must be able to store zero to the number of
- * desired colors.  16 bits/cell is plenty for that too.)
- * Since the JPEG code is intended to run in small memory model on 80x86
- * machines, we can't just allocate the histogram in one chunk.  Instead
- * of a true 3-D array, we use a row of pointers to 2-D arrays.  Each
- * pointer corresponds to a C0 value (typically 2^5 = 32 pointers) and
- * each 2-D array has 2^6*2^5 = 2048 or 2^6*2^6 = 4096 entries.  Note that
- * on 80x86 machines, the pointer row is in near memory but the actual
- * arrays are in far memory (same arrangement as we use for image arrays).

- * These routines are concerned with the time-critical task of mapping input
- * colors to the nearest color in the selected colormap.
- *
- * We re-use the histogram space as an "inverse color map", essentially a
- * cache for the results of nearest-color searches.  All colors within a
- * histogram cell will be mapped to the same colormap entry, namely the one
- * closest to the cell's center.  This may not be quite the closest entry to
- * the actual input color, but it's almost as good.  A zero in the cache
- * indicates we haven't found the nearest color for that cell yet; the array
- * is cleared to zeroes before starting the mapping pass.  When we find the
- * nearest color for a cell, its colormap index plus one is recorded in the
- * cache for future use.  The pass2 scanning routines call fill_inverse_cmap
- * when they need to use an unfilled entry in the cache.
- *
- * Our method of efficiently finding nearest colors is based on the "locally
- * sorted search" idea described by Heckbert and on the incremental distance
- * calculation described by Spencer W. Thomas in chapter III.1 of Graphics
- * Gems II (James Arvo, ed.  Academic Press, 1991).  Thomas points out that
- * the distances from a given colormap entry to each cell of the histogram can
- * be computed quickly using an incremental method: the differences between
- * distances to adjacent cells themselves differ by a constant.  This allows a
- * fairly fast implementation of the "brute force" approach of computing the
- * distance from every colormap entry to every histogram cell.  Unfortunately,
- * it needs a work array to hold the best-distance-so-far for each histogram
- * cell (because the inner loop has to be over cells, not colormap entries).
- * The work array elements have to be INT32s, so the work array would need
- * 256Kb at our recommended precision.  This is not feasible in DOS machines.
- *
- * To get around these problems, we apply Thomas' method to compute the
- * nearest colors for only the cells within a small subbox of the histogram.
- * The work array need be only as big as the subbox, so the memory usage
- * problem is solved.  Furthermore, we need not fill subboxes that are never
- * referenced in pass2; many images use only part of the color gamut, so a
- * fair amount of work is saved.  An additional advantage of this
- * approach is that we can apply Heckbert's locality criterion to quickly
- * eliminate colormap entries that are far away from the subbox; typically
- * three-fourths of the colormap entries are rejected by Heckbert's criterion,
- * and we need not compute their distances to individual cells in the subbox.
- * The speed of this approach is heavily influenced by the subbox size: too
- * small means too much overhead, too big loses because Heckbert's criterion
- * can't eliminate as many colormap entries.  Empirically the best subbox
- * size seems to be about 1/512th of the histogram (1/8th in each direction).
- *
- * Thomas' article also describes a refined method which is asymptotically
- * faster than the brute-force method, but it is also far more complex and
- * cannot efficiently be applied to small subboxes.  It is therefore not
- * useful for programs intended to be portable to DOS machines.  On machines
- * with plenty of memory, filling the whole histogram in one shot with Thomas'
- * refined method might be faster than the present code --- but then again,
- * it might not be any faster, and it's certainly more complicated.

+  *  //decoder declaration
+  *  ISVCDecoder *pSvcDecoder;
+  *  //input: encoded bitstream start position; should include start code prefix
+  *  unsigned char *pBuf =...;

+  *  sDstParseInfo.pDstBuff = new unsigned char[PARSE_SIZE]; //In Parsing only, allocate enough buffer to save transcoded bitstream for a frame
+  *
+  * @endcode
+  *
+  * Step 2:decoder creation
+  * @code
+  *  WelsCreateDecoder(&pSvcDecoder);
+  * @endcode
+  *
+  * Step 3:declare required parameter, used to differentiate Decoding only and Parsing only
+  * @code
+  *  SDecodingParam sDecParam = {0};
+  *  sDecParam.sVideoProperty.eVideoBsType = VIDEO_BITSTREAM_AVC;
+  *  //for Parsing only, the assignment is mandatory
+  *  sDecParam.bParseOnly = true;
+  * @endcode
+  *
+  * Step 4:initialize the parameter and decoder context, allocate memory
+  * @code
+  *  pSvcDecoder->Initialize(&sDecParam);
+  * @endcode
+  *
+  * Step 5:do actual decoding process in slice level;
+  *        this can be done in a loop until data ends
+  * @code
+  *  //for Decoding only
+  *  iRet = pSvcDecoder->DecodeFrameNoDelay(pBuf, iSize, pData, &sDstBufInfo);
+  *  //or

+  *  If (iRet != 0){
+  *      //error handling (RequestIDR or something like that)
+  *  }

+  *  if (sDstBufInfo.iBufferStatus==1){
+  *      //output handling (pData[0], pData[1], pData[2])
+  *  }
+  * //for Parsing only, sDstParseInfo can be used for, e.g., HW decoding
+  *  if (sDstBufInfo.iNalNum > 0){
+  *      //Hardware decoding sDstParseInfo;
+  *  }
+  *  //no-delay decoding can be realized by directly calling DecodeFrameNoDelay(), which is the recommended usage.
+  *  //no-delay decoding can also be realized by directly calling DecodeFrame2() again with NULL input, as in the following. In this case, decoder would immediately reconstruct the input data. This can also be used similarly for Parsing only. Consequent decoding error and output indication should also be considered as above.
+  *  iRet = pSvcDecoder->DecodeFrame2(NULL, 0, pData, &sDstBufInfo);
+  *  //judge iRet, sDstBufInfo.iBufferStatus ...
+  * @endcode
+  *
+  * Step 6:uninitialize the decoder and memory free
+  * @code
+  *  pSvcDecoder->Uninitialize();
+  * @endcode
