@@ -0,0 +1,52 @@ +TurboJPEG Java Wrapper +====================== + +The TurboJPEG shared library can optionally be built with a Java Native +Interface wrapper, which allows the library to be loaded and used directly from +Java applications. The Java front end for this is defined in several classes +located under org/libjpegturbo/turbojpeg. The source code for these Java +classes is licensed under a BSD-style license, so the files can be incorporated +directly into both open source and proprietary projects without restriction. A +Java archive (JAR) file containing these classes is also shipped with the +"official" distribution packages of libjpeg-turbo. + +TJExample.java, which should also be located in the same directory as this +README file, demonstrates how to use the TurboJPEG Java API to compress and +decompress JPEG images in memory. + + +Performance Pitfalls +-------------------- + +The TurboJPEG Java API defines several convenience methods that can allocate +image buffers or instantiate classes to hold the result of compress, +decompress, or transform operations. However, if you use these methods, then +be mindful of the amount of new data you are creating on the heap. It may be +necessary to manually invoke the garbage collector to prevent heap exhaustion +or to prevent performance degradation. Background garbage collection can kill +performance, particularly in a multi-threaded environment (Java pauses all +threads when the GC runs.) + +The TurboJPEG Java API always gives you the option of pre-allocating your own +source and destination buffers, which allows you to re-use those buffers for +compressing/decompressing multiple images. If the image sequence you are +compressing or decompressing consists of images of the same size, then +pre-allocating the buffers is recommended. + + +Installation Directory +---------------------- + +The TurboJPEG Java Wrapper will look for the TurboJPEG JNI library +(libturbojpeg.so, libturbojpeg.jnilib, or turbojpeg.dll) in the system library +paths or in any paths specified in LD_LIBRARY_PATH (Un*x), DYLD_LIBRARY_PATH +(Mac), or PATH (Windows.) Failing this, on Un*x and Mac systems, the wrapper +will look for the JNI library under the library directory configured when +libjpeg-turbo was built. If that library directory is +/opt/libjpeg-turbo/lib32, then /opt/libjpeg-turbo/lib64 is also searched, and +vice versa. + +If you installed the JNI library into another directory, then you will need +to pass an argument of -Djava.library.path={path_to_JNI_library} to java, or +manipulate LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, or PATH to include the directory +containing the JNI library.

The TurboJPEG API allows both the JPEG compression and + decompression pipelines to be split into stages: YUV encode, compress from + YUV, decompress to YUV, and YUV decode. A <code>YUVImage</code> instance + serves as the destination image for YUV encode and decompress-to-YUV + operations and as the source image for compress-from-YUV and YUV decode + operations. + <p> + Technically, the JPEG format uses the YCbCr colorspace (which technically is + not a "colorspace" but rather a "color transform"), but per the convention + of the digital video community, the TurboJPEG API uses "YUV" to refer to an + image format consisting of Y, Cb, and Cr image planes. + <p> + Each plane is simply a 2D array of bytes, each byte representing the value + of one of the components (Y, Cb, or Cr) at a particular location in the + image. The width and height of each plane are determined by the image + width, height, and level of chrominance subsampling. The luminance plane + width is the image width padded to the nearest multiple of the horizontal + subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of + 4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane + height is the image height padded to the nearest multiple of the vertical + subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4 + or grayscale.) The chrominance plane width is equal to the luminance plane + width divided by the horizontal subsampling factor, and the chrominance + plane height is equal to the luminance plane height divided by the vertical + subsampling factor. + <p> + For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is + used, then the luminance plane would be 36 x 35 bytes, and each of the + chrominance planes would be 18 x 35 bytes. If you specify a line padding of + 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and + each of the chrominance planes would be 20 x 35 bytes.</div> +</li> +</ul> +</div>
