| * builds/toplevel.mk (dist): Use older POSIX standard for `tar'. | |
| Apparently, BSD tar isn't capable yet of handling POSIX-1.2001 | |
| (contrary to GNU tar), so force the POSIX-1.1988 format. | |

| [gxvalid] Fix a naming convention conflicting with ftvalid. | |
| See previous changeset for otvalid. | |
| * src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace | |
| `valid' by `gxvalid'. | |
| * src/gxvalid/{gxvbsln.c, gxvcommn.c, gxvfeat.c, gxvjust.c, | |

| gxvprop.c, gxvtrak.c}: Replace `valid' by `gxvalid' if | |
| it is typed as GXV_Validator. | |
| 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [otvalid] Fix a naming convention conflicting with ftvalid. | |
| Some prototypes in ftvalid.h use `valid' for the variables | |
| typed as FT_Validator. Their implementations in src/base/ | |
| ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar. | |
| Some macros in otvcommn.h assume the exist of the variable | |
| `valid' typed as OTV_Validator in the caller. | |
| Mixing these two conventions cause invalid pointer conversion | |
| and unexpected SEGV in longjmp. To prevent it, all variables | |
| typed as OTV_Validator are renamed to `otvalid'. | |
| * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'. | |
| * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c, | |
| otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid' | |
| if it is typed as OTV_Validator. | |
| 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros. | |
| Original patch is designed by Werner Lemberg. Extra part | |
| for otvalid and gxvalid are added by suzuki toshiya, see | |

| * src/gxvalid/gxvcommn.h: Ditto. | |
| * src/otvalid/otvcommn.h: Ditto. | |
| 2014-12-08 Werner Lemberg <wl@gnu.org> | |
| [pcf] Fix Savannah bug #43774. | |
| Work around `features' of X11's `pcfWriteFont' and `pcfReadFont' | |
| functions. Since the PCF format doesn't have an official | |
| specification, we have to exactly follow these functions' behaviour. | |
| The problem was unveiled with a patch from 2014-11-06, fixing issue | |
| #43547. | |
| * src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last | |
| element. Instead, assign real size. | |
| 2014-12-07 Werner Lemberg <wl@gnu.org> | |
| Work around a bug in Borland's C++ compiler. | |
| See | |

| docs/CHANGES: Updated, formatted. | |
| 2014-12-04 Dave Arnold <darnold@adobe.com> | |
| [cff] Modify an FT_ASSERT. | |
| * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah | |
| bug #43661, the test font `...aspartam.otf' still triggers an | |
| FT_ASSERT. Since hintmap still works with count==0, ... | |
| (cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to | |
| suppress the assert. | |
| 2014-12-04 Dave Arnold <darnold@adobe.com> | |
| [cff] Fix Savannah bug #43661. | |
| * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, | |

| hintmask is constructed. | |
| * src/cff/cf2hints.c (cf2_hintmap_build): Add defensive code to | |
| avoid reading past end of hintmask. | |
| 2014-12-03 Werner Lemberg <wl@gnu.org> | |
| docs/CHANGES: Updated. | |
| 2014-12-03 Werner Lemberg <wl@gnu.org> | |
| [autofit] Better fix for conversion specifiers in debug messages. | |
| Using `%ld' for pointer differences causes warnings on 32bit | |
| platforms. The correct type would be (the relatively new) `%td', | |
| however, this is missing on some important platforms. | |
| This patch improves the change from 2014-11-28. | |
| * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our | |
| pointer differences are always sufficiently small. | |
| (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, | |
| af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'. | |
| 2014-12-03 Werner Lemberg <wl@gnu.org> | |
| FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality. | |
| All public FreeType enumeration and flag values are uppercase... | |
| * include/tttables.h (FT_Sfnt_Tag): Implement it. For backwards | |
| compatilibity, retain the old values as macros. | |
| * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c | |
| (get_sfnt_table): Updated. | |
| 2014-12-02 Werner Lemberg <wl@gnu.org> | |
| * include/*: Improve structure of documentation. | |
| . Add and update many `<Order>' tags. | |
| . Apply various documentation fixes. | |
| . Remove details to deprecated (or never implemented) data. | |
| 2014-12-02 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Always handle `<Order>' section elements. | |
| Previously, those elements were handled only for sections present in | |
| a `<Sections>' chapter element. | |
| * src/tools/docmaker/content.py (ContentProcessor::finish): | |
| Implement it. | |
| 2014-12-02 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Properly handle empty rows in Synopsis. | |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit | |
| ` ' for empty fields. | |
| 2014-12-02 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Thinko. | |
| * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): | |
| Emit `/empty/' string for first element also. | |
| 2014-12-02 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Honour empty lines in `<Order>' section element. | |
| This greatly improves the readability of the `Synopsis' links. | |
| * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): | |
| Insert string `/empty/' between items. | |
| * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it | |
| robust against nonexistent keys. | |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit | |
| empty <td> elements for `/empty/'. | |
| 2014-12-02 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Ensure Python 3 compatibility. | |
| * src/tools/docmaker/content.py (ContentProcessor::set_section, | |
| ContentProcessor::finish): Replace `has_key' function with `in' | |
| keyword. | |
| * src/tools/docmaker/formatter.py (Formatter::__init__): Replace | |
| sorting function with a key generator. | |
| (Formatter::add_identifier): Replace `has_key' function with `in' | |
| keyword. | |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote): | |
| Replace `has_key' function with `in' keyword. | |
| (HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use | |
| integer division. | |
| s/<>/>/. | |
| * src/tools/docmaker/utils.py: Import `itertools'. | |
| (index_sort): Replaced by... | |
| (index_key): ... this new key generator (doing exactly the same). | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Don't output a block multiple times. | |
| This bug was hidden by not processing all lines of `<Order>' blocks. | |
| * src/tools/docmaker/formatter.py (Formatter::section_dump): Filter | |
| out field names. | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Use field values as HTML link targets where possible. | |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url): | |
| Accept second, optional argument to specify a name. | |
| (HtmlFormatter::html_source_quote): Link to field ID if possible. | |
| (HtmlFormatter::print_html_field_list): Emit `id' attribute. | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Allow empty lines in `<Order>' blocks. | |
| Before this patch, the suggested order of entries stopped at the | |
| first empty line. | |
| Obviously, nobody noticed that this problem caused a much reduced | |
| set of links in the `Synopsis' sections; in particular, the | |
| `<Order>' blocks contain a lot of entries that wouldn't be listed | |
| otherwise... | |
| * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): | |
| New function to iterate over all items. | |
| (DocSection::process): Use it. | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| * src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp. | |
| After the single asterisk there must be no other immediately following | |
| asterisk. | |

| * src/tools/docmaker/tohtml.py: Introduce a new table class `toc', | |
| together with proper CSS. | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Provide higher-level markup and simplify HTML. | |
| * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>' | |
| elements, use CSS descendants (of class `section') to format the | |
| data. | |
| Also remove reduntant <p> and <br> elements, replacing them with | |
| proper CSS. | |
| Globally reduce page width to 75%. | |
| (block_header): Rename <div> class to `section'. | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Add `top' links after blocks. | |
| * src/tools/docmaker/tohtml.py (block_footer_middle): Implement it. | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| * src/tools/docmaker/tohtml.py: Improve CSS for fields. | |
| Make fields align horizontally relative to full line width. | |
| 2014-11-29 Werner Lemberg <wl@gnu.org> | |
| * src/tools/docmaker/tohtml.py: Fix index and TOC templates. | |
| This thinko was introduced 2014-11-27. | |
| 2014-11-28 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Format field lists with CSS. | |
| This also simplifies the inserted HTML code. | |
| * src/tools/docmaker/tohtml.py | |
| (HtmlFormatter::print_html_field_list): Do it. | |
| 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| Fix compiler warning to the comparison between signed and | |
| unsigned variable. | |
| * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison | |
| between `ypos + ysize' and FT_INT_{MAX,MIN}. | |
| 2014-11-28 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Replace empty `<td>' with CSS. | |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do | |
| it. | |
| 2014-11-28 Werner Lemberg <wl@gnu.org> | |
| [docmaker] Replace some `<table>' tags with `<h4>' and `<div>'. | |
| * src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'. | |
| (source_*): Use `<div>'. | |
| (HtmlFormatter::block_enter): s/<h4>/<h3>/. | |
| 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| Fix compiler warning to conversion specifiers in debug messages. | |
| * src/autofit/afhints.c (af_glyph_hints_dump_points): Add length | |
| modifier to dump long integers. | |

| [docmaker] Replace `name' attribute of `<a>' with `id'. | |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it. | |
| 2014-11-27 Werner Lemberg <wl@gnu.org> | |
| * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes. | |
| For `Index' and `TOC' links, we now simply use the `text-align' CSS | |
| property of `<td>' to enforce flush-left and flush-right, | |
| eliminating the hack with an empty, full-width `<td>' element | |
| inbetween. | |
| The change also enforces the same (smaller) size for all index and | |
| TOC links. | |
| 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| * src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(), | |
| cf2font.c could not find it under `make multi' build. | |
| 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove | |
| unrequired negative value check for `width' and `height'. | |
| 2014-11-27 Werner Lemberg <wl@gnu.org> | |

| Replace some `<table>' tags with `<div>' to simplify structure. | |
| Move `bgcolor' attribute to CSS. | |
| Replace most `width' attributes with CSS. The remaining instances | |
| (providing a similar effect as LaTeX's `\hfill' command) are removed | |
| in a later patch. | |
| 2014-11-27 Werner Lemberg <wl@gnu.org> | |
| * src/tools/docmaker/tohtml.py: Replace <font> with CSS. | |
| 2014-11-27 Werner Lemberg <wl@gnu.org> | |
| * src/tools/docmaker/tohtml.py: Center <table> with CSS. | |
| 2014-11-27 Werner Lemberg <wl@gnu.org> | |

| 2014-11-27 Werner Lemberg <wl@gnu.org> | |
| * src/tools/docmaker/tohtml.py: Remove redundant `<center>' tags. | |
| This starts a series of commits into the direction of generating | |
| valid HTML 5 code, especially using much more CSS. | |
| 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| Prevent too negative values (< FT_INT_MIN) in bitmap metrics, | |
| suggested by Alexei. | |
| * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Prevent too | |
| negative values in `xpos' and `ypos + ysize'. | |
| * src/smooth/ftsmooth.c (ft_smooth_render_generic): Prevent | |
| too negative values in `x_left' and `y_top'. Either negative | |
| values in `width' and `height' are checked. | |

| [docmaker] Produce better HTML code. | |
| * src/tools/docmaker/tohtml.py: Always use double quotes for | |
| attribute values. | |
| (source_footer): Close `td' and `tr' groups. | |
| 2014-11-27 Werner Lemberg <wl@gnu.org> | |
| Use better way to disable creation of .pyc files for `make refdoc'. | |

| * builds/detect.mk (std_setup, dos_setup): Mention required python | |
| version for `refdoc' target. | |

| non-grouping parentheses. | |

| Updated. | |
| 2014-11-27 Werner Lemberg <wl@gnu.org> | |
| * src/base/ftobjs.c (FT_Get_Glyph_Name): Fix compiler warning. | |
| Introdruced in previous change. Reported by Alexei. | |
| 2014-11-26 Werner Lemberg <wl@gnu.org> | |
| * src/*: Add checks for parameters of API functions where missing. | |
| `API functions' are functions tagged with `FT_EXPORT_DEF'. | |
| Besides trivial fixes, the following changes are included, too. | |
| * src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set | |

| `outline' parameter to `Invalid_Outline'. | |
| 2014-11-26 Werner Lemberg <wl@gnu.org> | |
| * src/cache/ftcbasic.c: Use single calls to `FT_TRACE'. | |
| 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |

| [cff, pfr, psaux, winfonts] Fix Savannah bug #43676. | |
| Don't cast cmap init function pointers to an incompatible type. | |
| Without this patch, the number of parameters between declaration and | |
| the real signature differs. Calling such a function results in | |
| undefined behavior. | |
| ISO/IEC 9899:TC3 (Committee Draft September 7, 2007) | |
| 6.5.2.2 Function calls | |
| 9 If the function is defined with a type that is not | |
| compatible with the type (of the expression) pointed to by | |
| the expression that denotes the called function, the | |
| behavior is undefined. | |
| On certain platforms (c -> js with emscripten) this causes | |
| termination of execution or invalid calls because in the emscripten | |
| implementation, function pointers of different types are stored in | |
| different pointer arrays. Incorrect pointer type here results in | |
| indexing of an incorrect array. | |

| Avoid compiler warnings on x86-64 for `FT_MulFix'. | |
| `FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h', | |
| but several inline implementations of it in `ftcalc.h' take | |
| `FT_Int32' arguments. This is causing compiler warnings on x86-64: | |
| If parameters of type `FT_Fixed' (= `FT_Long') are passed to the | |
| inline implementation of this function, integer values are truncated | |
| from 64bit to 32bit. | |

| [base] CORDIC improvements. | |
| The scaling between the hypotenuse and its CORDIC approximation is | |

| 2014-11-03 Werner Lemberg <wl@gnu.org> | |
| * src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting. | |
| Before this patch, it was impossible to ever call DELTAP[123] in | |
| subpixel hinting mode as described in the ClearType whitepaper; it | |
| only worked if in `compatibility mode'. However, compatibility mode | |
| essentially disables SHPIX, completely ruining hinting of | |
| ttfautohint output, for example. | |
| We now follow the whitepaper more closely so that DELTAP[123] | |
| instructions for touched points in the non-subpixel direction are | |
| executed. | |

| [base] Significant optimization of `ft_div64by32' | |
| We shift as many bits as we can into the high register, perform | |

| [autofit] Fix Savannah bug #42148. | |
| The adaptation of the cjk auto-hinter module to blue stringsets in | |
| 2013-08-25 had three severe bugs. Mea culpa. | |
| 1. Contrary to the latin auto-hinter, characters for reference and | |
| overshoot values of a blue zone are specified separately. Due to | |
| the screwed-up change it didn't work at all. | |
| 2. A boolean comparison was erroneously replaced with a cast, | |
| causing invalid results with the `^' operator later on. The | |
| visual artifact caused by this problem is the topic of the bug | |
| report. | |
| 3. Two flag values were inverted, causing incorrect assignment of | |
| reference and overshoot values. | |
| * src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new | |
| syntax to have both reference and overshoot characters in a single | |
| string. This is error #1. | |
| Add extensive comments. | |
| * src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no | |
| longer used. | |
| (AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values. | |
| This is error #3. | |
| * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. | |
| * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1. | |
| Use character `|' to separate characters for reference and overshoot | |
| values. | |
| Improve tracing messages, synchronizing them with the latin | |
| auto-hinter. | |
| (af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'. | |
| This is error #2. | |

| [autofit] Redesign the recognition algorithm of strong points. | |
| In particular, local extrema without horizontal or vertical segments | |
| are better recognized: | |
| + A + D | |
| \ / | |
| \ / | |
| \ / | |
| \ / | |
| \ + C | |
| \ / | |
| B +/ | |
| If the distances AB and CD are large, point B wasn't previously | |
| detected as an extremum since the `ft_corner_is_flat' function | |
| `swallowed' BC regardless of its direction, tagging point B as weak. | |
| The next iteration started at B and made `ft_corner_is_flat' swallow | |
| point C, tagging it as weak also, et voilà. | |
| To improve that, another pass gets now performed before calling | |
| `ft_corner_is_flat' to improve the `topology' of an outline: A | |
| sequence of non-horizontal or non-vertical vectors that point into | |
| the same quadrant are handled as a single, large vector. | |
| Additionally, distances of near points are now accumulated, which | |
| makes the auto-hinter handle them as if they were prepended to the | |
| next non-near vector. | |
| This generally improves the auto-hinter's rendering results. | |
| * src/autofit/afhints.c (af_glyph_hints_reload): Implement it. | |
| * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag | |
| `AF_FLAG_NEAR'. | |
| 2014-04-05 Werner Lemberg <wl@gnu.org> | |
| [autofit] Improve scoring algorithm for identifying stems. | |
| Problem reported by Karsten Lücke <karsten.luecke@kltf.de>. | |
| The new algorithm takes care of the width of stems: If the distance | |
| between two segments is larger than the largest stem width, the | |
| demerits quickly increase for larger distances. This improves | |

| pkg-config for bzip2 since not all GNU/Linux distributions have | |
| `bzip2.pc' (and the header file `bzlib.h' is located in /usr/include | |
| normally). | |

| 2014-03-03 Werner Lemberg <wl@gnu.org> | |
| Rewrite library option handling in `configure'. | |
| o Introduce `auto' value for `--with-XXX' library options; this is | |
| now the default. | |
| o First use `pkg-config' for library detection, then fall back to | |
| other tests. | |
| * builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png, | |
| --with-harfbuzz): Rewrite. | |
| Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf' | |
| variables to collect data for `freetype2.pc' and `freetype-config'. | |

| 2014-03-01 Werner Lemberg <wl@gnu.org> | |
| Avoid `long long' warnings with older gcc compilers. | |
| Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. | |
| * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for | |
| versions < 4.6. This is especially needed for Max OS X since this | |
| OS runs a gcc variant (or emulation) based on version 4.2.1. | |
| 2014-03-01 Werner Lemberg <wl@gnu.org> | |
| * docs/INSTALL.CROSS: Revised and updated. | |
| 2014-03-01 Werner Lemberg <wl@gnu.org> | |

| This is a generated file at build time, not configure time. | |
| * builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ... | |
| (CLEAN): This variable. | |
| 2014-03-01 Werner Lemberg <wl@gnu.org> | |
| Use pkg-config for detecting libpng and libbz2 also. | |
| * builds/unix/configure.raw (HAVE_PKG): New variable. | |

| [cff] Fix Savannah bug #41697, part 2. | |
| * src/cff/cf2ft.c (cf2_initLocalRegionBuffer, | |
| cf2_initGlobalRegionBuffer): It is possible for a charstring to call | |
| a subroutine if no subroutines exist. This is an error but should | |
| not trigger an assert. Split the assert to account for this. | |
| 2014-02-28 Dave Arnold <darnold@adobe.com> | |
| [cff] Fix Savannah bug #41697, part 1. | |
| * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is | |
| invalid. In this case, it is not safe to use the length of | |
| `hStemHintArray'; the exception has already been recorded in | |
| `hintMask'. | |
| 2014-02-26 Werner Lemberg <wl@gnu.org> | |
| [sfnt] Fix Savannah bug #41696. | |

| * src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array. | |
| 2014-02-26 Werner Lemberg <wl@gnu.org> | |
| [bdf] Fix Savannah bug #41692. | |
| bdflib puts data from the input stream into a buffer in chunks of | |
| 1024 bytes. The data itself gets then parsed line by line, simply | |
| increasing the current pointer into the buffer; if the search for | |
| the final newline character exceeds the buffer size, more data gets | |
| read. | |
| However, in case the current line's end is very near to the buffer | |
| end, and the keyword to compare with is longer than the current | |
| line's length, an out-of-bounds read might happen since `memcmp' | |
| doesn't stop properly at the string end. | |
| * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons | |
| stop at string ends. | |
| 2014-02-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [autofit] Fix `make multi' compilation. | |

| [autofit] Fix Indic scripts. | |
| Split the single, incorrect Indic entry into separate scripts so | |
| that the covered ranges are the same: Bengali, Devanagari, Gujarati, | |
| Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese, | |
| Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove | |
| entries for Meetai Mayak and Sharada – the Unicode ranges were | |
| incorrect (and nobody has complained about that), fonts are scarce | |
| for those scripts, and the Indic auto-hinter support is rudimentary | |
| anyways. | |
| * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and | |
| AF_CONFIG_OPTION_CJK. | |
| * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro. | |
| Use it, together with AF_CONFIG_OPTION_INDIC and | |
| AF_CONFIG_OPTION_CJK, to update. | |
| * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated. | |
| [!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed. | |
| Sort entries by tags. | |

| [autofit] Thinko. | |
| * src/autofit/hbshim.c (af_get_char_index): Similar to | |
| `af_get_coverage', reject glyphs which are not substituted. | |
| 2014-01-03 Werner Lemberg <wl@gnu.org> | |
| [autofit] Fix handling of default coverages. | |
| With this commit, the implementation of coverage handling is | |
| completed. | |
| * src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to | |
| do. | |
| Reject coverages which don't contain appropriate glyphs for blue | |
| zones. | |
| 2014-01-03 Werner Lemberg <wl@gnu.org> | |
| [autofit] Fix handling of default coverages. | |
| * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): | |
| First handle non-default coverages, then the default coverage of the | |
| default script, and finally the other default coverages. | |
| 2014-01-03 Werner Lemberg <wl@gnu.org> | |
| [autofit] Fix scaling of HarfBuzz shaping. | |
| * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM. | |
| 2014-01-03 Werner Lemberg <wl@gnu.org> | |
| [autofit] Better ftgrid support. | |
| * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add | |
| parameters `is_blue' and `blue_offset'. | |
| 2014-01-01 Werner Lemberg <wl@gnu.org> | |
| [autofit] Remove some styles. | |
| * src/autofit/afcover.h: Remove coverages for alternative fractions, | |
| denominators, numerators, and fractions. | |

| 2014-01-01 Werner Lemberg <wl@gnu.org> | |
| [autofit] Add more styles. | |
| * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New | |
| auxiliary macros; use them to define styles for Cyrillic, Greek, and | |
| Latin. | |
| * src/autofit/afcover.h: Remove coverage for oldstyle figures. | |
| Since those digits are used in combination with ordinary letters, it | |
| makes no sense to handle them separately. | |
| * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit | |
| `options' parameter to 4 bits. | |
| 2014-01-01 Werner Lemberg <wl@gnu.org> | |

| [autofit] Fix interface of `af_get_char_index'. | |
| * src/autofit/hbshim.c (af_get_char_index): Return error value. | |
| Add argument for y offset (to be used in a yet-to-come patch). | |
| * src/autofit/hbshim.h, src/autofit/afcjk.c, | |
| src/autofit/aflatin.c: Updated. | |
| 2013-12-30 Werner Lemberg <wl@gnu.org> | |
| [autofit] Don't combine multiple features into one set. | |
| Combining them, as originally envisioned, would lead to much more | |
| complicated code, as investigations have shown meanwhile. The major | |
| drawback is that we run out of available style slots much earlier. | |
| However, this is only a theoretical issue since we don't support a | |
| large number of scripts currently. | |
| * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with | |
| a single-element `COVERAGE' macro, sort the elements by the feature | |
| tags, and add entry for `ruby'. | |
| * src/autofit/aftypes.h: Updated. | |
| * src/autofit/hbshim.c: Updated. | |
| 2013-12-28 Werner Lemberg <wl@gnu.org> | |

| unconditionally. | |
| 2013-12-28 Werner Lemberg <wl@gnu.org> | |
| [autofit] Add wrapper function for `FT_Get_Char_Index'. | |
| Yet-to-come changes will provide HarfBuzz functionality for the new | |

| * src/autofit/hbshim.h: Updated. | |

| Updated. | |
| 2013-12-28 Werner Lemberg <wl@gnu.org> | |
| [autofit] Use `global' HarfBuzz font object. | |
| We now use `hb_font' instead of `hb_face' since yet-to-come changes | |
| need this. | |
| * src/autofit/afglobal.h: Include `hbshim.h'. | |
| (AF_FaceGlobalsRec) [FT_CONFIG_OPTION_USE_HARFBUZZ]: New member | |
| `hb_font'. | |

| [ftrfork] Fix the face order difference between POSIX and Carbon. | |
| The fragmented resources in Suitcase and .dfont should be reordered | |
| when `POST' resource for Type1 is being restored, but reordering of | |
| sfnt resources induces the different face order. Now the ordering | |
| is restricted to `POST' resource only, to prevent the different | |
| order issue (e.g. the face index in the fontconfig cache generated | |
| with Carbon framework is incompatible with that by FreeType 2 | |
| without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung. | |

| 2013-12-21 Werner Lemberg <wl@gnu.org> | |
| [autofit] Introduce `coverages'. | |
| Coverages are the interface to the HarfBuzz library to acces | |
| OpenType features for handling glyphs not addressable by the cmap. | |
| Right now, compilation of HarfBuzz is only added to the development | |
| build. A solution for standard build mode will be delayed until | |
| HarfBuzz gets split into two libraries to avoid mutual dependencies | |
| between FreeType and HarfBuzz. | |
| Note that this is only a first step in handling coverages, basically | |
| providing the framework only. Code for handling selected OpenType | |
| features (this is, actually using the data in `afcover.h') will | |
| follow. | |

| data. | |

| * src/truetype/ttinterp.c (Ins_IP): Fix sign typo to make FreeType | |
| behave the same as the Windows TrueType engine for the invalid case. | |
| 2013-12-21 Werner Lemberg <wl@gnu.org> | |
| [autofit] Make PIC mode work actually. | |
| * src/autofit/afpic.h (AFModulePIC): Fix array sizes to fit the | |
| enumeration values automatically generated by including `afscript.h' | |
| and friends. | |

| src/autofit/aflatin.c (af_latin_metrics_init_widths) | |
| [FT_CONFIG_OPTION_PIC]: Declare `globals'. | |
| * src/autofit/afglobal.c: Always call AF_DEFINE_SCRIPT_CLASS, and | |
| AF_DEFINE_STYLE_CLASS. | |
| * src/autofit/afpic.c: Include `afglobal.h'. | |
| (autofit_module_class_pic_init): Typo. | |
| * src/autofit/aftypes.h (AF_DEFINE_SCRIPT_CLASS, | |
| AF_DEFINE_STYLE_CLASS): Don't use the same identifier for macro | |
| parameter and structure member. | |
| 2013-12-20 Werner Lemberg <wl@gnu.org> | |

| [truetype] Next round in phantom point handling. | |
| Greg Hitchcock provided very interesting insights into the | |
| complicated history of the horizontal positions of the TSB and BSB | |
| phantom points. | |
| * src/truetype/ttgload.c (TT_LOADER_SET_PP) | |
| [TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and | |
| `grayscale_hinting' flags as conditionals for the x position of TSB | |
| and BSB. | |
| 2013-12-05 Werner Lemberg <wl@gnu.org> | |
| * builds/freetype.mk (FT_CC): Removed. Unused. | |
| 2013-12-04 Werner Lemberg <wl@gnu.org> | |
| [sfnt] Fix handling of embedded bitmap strikes. | |
| This corrects the commit from 2013-11-21. Problem reported by | |
| Andrey Panov <panov@canopus.iacp.dvo.ru>. | |
| * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Fix logic to | |
| detect excessive bytes for bit-aligned bitmaps. | |
| 2013-12-03 Werner Lemberg <wl@gnu.org> | |
| [truetype] Remove dead code. | |
| Reported by Nigel Tao <nigeltao@golang.org>. | |
| * include/internal/tttypes.h (TT_LoaderRec): Remove unused | |
| `preserve_pps' field. | |
| * src/truetype/ttgload.c (TT_Hint_Glyph): Updated. | |
| 2013-12-03 Werner Lemberg <wl@gnu.org> | |
| [truetype] Fix phantom point handling. | |
| This is a further improvement to the changes from 2013-11-06. | |
| * src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points | |
| are rounded horizontally, vertical ones are rounded vertically. | |
| (TT_LOADER_SET_PP): The horizontal position of vertical phantom | |
| points in pre-ClearType mode is zero, as shown in the OpenType | |
| specification. | |
| 2013-12-02 Werner Lemberg <wl@gnu.org> | |
| [truetype] Fix change from 2013-11-20. | |
| Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>. | |
| * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to | |
| `Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a | |
| `IS_HINTED' clause. | |
| Also remove redundant check using `maxSizeOfInstructions' – in | |
| simple glyphs, the bytecode data comes before the outline data, and | |
| a validity test for this is already present. | |
| 2013-11-27 Werner Lemberg <wl@gnu.org> | |
| [autofit] Fix use of dumping functions in `ftgrid' demo program. | |
| * src/autofit/afhints.c (AF_DUMP) [FT_DEBUG_AUTOFIT]: New macro. | |
| (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, | |
| af_glyph_hints_dump_edges) [FT_DEBUG_AUTOFIT]: Add parameter to | |
| handle output to stdout. | |
| Use AF_DUMP. | |
| (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, | |
| af_glyph_hints_dump_edges) [!FT_DEBUG_AUTOFIT]: Removed. | |

| Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. | |
| * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Don't trust glyph | |
| format. | |
| 2013-11-20 Werner Lemberg <wl@gnu.org> | |
| [truetype] Don't trust `maxp's `maxSizeOfInstructions'. | |
| Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see | |

| `TT_Process_Composite_Glyph' for handling unreliable values of | |
| `maxSizeOfInstructions'. | |
| 2013-11-16 Werner Lemberg <wl@gnu.org> | |
| [sfnt] Fix `OS/2' table version 5 support. | |
| We now follow the `official' announcement from Microsoft (on the | |
| OpenType mailing list, which unfortunately hasn't a public archive). | |
| * include/freetype/tttables.h (TT_OS2): | |
| s/usLowerPointSize/usLowerOpticalPointSize/, | |
| s/usUpperPointSize/usUpperOpticalPointSize/. | |
| * src/sfnt/ttload.c (tt_face_load_os2): Update, and set correct | |

| 2013-11-13 Werner Lemberg <wl@gnu.org> | |

| * builds/unix/install.mk (install): Updated. | |
| 2013-11-13 Werner Lemberg <wl@gnu.org> | |
| Simplify header file hierarchy. | |
| This large patch changes the header file directory layout from | |
| `include/freetype/...' to `include/...', effectively removing one | |
| level. Since the file `ft2build.h' is also located in `include' | |
| (and it stays there even after installation), all FreeType header | |
| files are now in a single directory. | |
| Applications that use (a) `freetype-config' or FreeType's | |
| `pkg-config' file to get the include directory for the compiler, and | |
| (b) the documented way for header inclusion like | |
| #include <ft2build.h> | |
| #include FT_FREETYPE_H | |
| ... | |
| don't need any change to the source code. | |
| * include/freetype/*: Move up to... | |
| * include/*: ... this directory. | |
| * builds/amiga/include/freetype/*: Move up to... | |
| * builds/amiga/include/*: ... this directory. | |
| */*: Essentially do `s@/freetype/@/@' where appropriate. | |
| * CMakeList.txt: Simplify. | |
| * builds/unix/freetype-config.in, builds/unix/freetype2.in: For | |
| `--cflags', return a single directory. | |
| * builds/unix/install.mk (install): No longer try to remove `cache' | |
| and `internal' subdirectories; instead, remove the `freetype' | |
| subdirectory. | |
| 2013-11-12 Werner Lemberg <wl@gnu.org> | |
| [truetype] Fix last `truetype' commit. | |

| finding index value of insertion point. | |
| 2013-11-06 Werner Lemberg <wl@gnu.org> | |
| [truetype] Fix handling of phantom points in composite glyphs. | |
| Problem reported by Nigel Tao <nigeltao@golang.org>. | |
| This is a follow-up commit to the previous one. | |
| * src/truetype/ttgload.c (load_truetype_glyph): Call | |
| `tt_get_metrics' after loading the glyph header. | |
| 2013-11-06 Werner Lemberg <wl@gnu.org> | |
| [truetype] Improve emulation of vertical metrics. | |
| This commit also improves the start values of vertical phantom | |
| points. Kudos to Greg Hitchcock for help. | |
| * src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass | |
| `yMax' value. Replace code with fixed Microsoft definition. | |
| (tt_get_metrics): Updated. | |
| (TT_LOADER_SET_PP): Add explanation how to initialize phantom | |
| points, taken from both the OpenType specification and private | |
| communication with Greg (which will eventually be added to the | |
| standard). | |
| Fix horizontal position of `pp3' and `pp4'. | |

| * docs/CHANGES: Updated. | |
| 2013-11-01 Werner Lemberg <wl@gnu.org> | |
| [truetype] Minor code refactoring. | |
| Two benefits: The allocated FDEF (and IDEF) array gets slightly | |
| smaller, and the `ttdebug' demo program has access to function | |
| numbers without additional costs. | |
| Fortunately, no changes to FontForge are necessary – this is the | |
| only external TrueType debugger I know of, but others may exist and | |
| should check the code accordingly. | |
| * src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and | |
| `Cur_End' with a pointer to the corresponding `TT_DefRecord' | |
| structure. | |
| * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF, | |
| Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>): | |
| Updated. | |
| 2013-10-27 Werner Lemberg <wl@gnu.org> | |
| [sfnt] Implement support for `OS/2' table version 5. | |
| See | |
| http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism | |
| for the announcement. | |
| * include/freetype/tttables.h (TT_OS2): Add fields | |
| `usLowerPointSize' and `usUpperPointSize'. Since FreeType returns | |
| this structure only as a pointer through `FT_Get_Sfnt_Table', there | |
| shouldn't be any ABI problems. | |
| * src/sfnt/ttload.c (tt_face_load_os2): Implement it. | |
| * docs/CHANGES: Updated. | |

| [arm] Fix thumb2 inline assembly under LLVM. | |
| When using `ADD' with an immediate operand, the instruction is | |
| actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the | |
| immediate operand cannot exceed 4095. It will fail to compile with | |
| LLVM. | |
| However, in GCC, due to some legacy compatibility considerations, | |
| `ADD.W' will be automatically emitted when the immediate operand is | |
| larger than 4095. | |

| 2013-10-03 Dave Arnold <darnold@adobe.com> | |
| * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero. | |
| Note that the old code avoided using a region of the piecewise | |
| linear function where the slope was zero. The recovery was to use a | |
| different section of the function, which produced a different, | |
| incorrect amount of darkening. | |

| * src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'. | |
| 2013-10-02 Dave Arnold <darnold@adobe.com> | |
| * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount. | |
| This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect | |
| is to use a previous darkening amount when producing an unhinted, | |
| unscaled outline. This can cause autohint samples in ftgrid and | |
| ftview to be based on darkened CFF outlines instead of unhinted, | |
| undarkened ones. | |
| 2013-09-29 Dave Arnold <darnold@adobe.com> | |
| Fix Savannah bug #39295. | |
| The bug was caused by switching to the initial hintmap (the one in | |
| effect when `moveto' executes) just before drawing the final element | |
| in the charstring. This ensured that the path was closed (in both | |
| Character Space and Device Space). But if the final element was a | |
| curve and if the final hintmap was different enough from the initial | |
| one, then the curve was visibly distorted. | |
| The first part of the fix is to draw the final curve using the final | |
| hintmap as specified by the charstring. This corrects the | |
| distortion but does not ensure closing in Device Space. It may | |
| require the rasterizer to automatically generate an extra closing | |
| line. Depending on the hintmap differences, this line could be from | |
| zero to a couple pixels in length. | |
| The second part of the fix covers the case where the charstring | |
| subpath is closed with an explicit line. We now modify that line's | |
| end point to avoid the distortion. | |
| Some glyphs in the bug report font (TexGyreHeros-Regular) that show | |
| the change are: | |
