0f6be064	2018-06-17T20:27:42	[bdf] Fix underflow of an unsigned value. bdflib.c:1562 could be reached with `font->glyphs_used == 0'. That caused an underflow of the unsigned value which results in undefined behaviour. * src/bdf/bdflib.c (src/bdf/bdflib.c): Bail out earlier than before if the `ENCODING' keyword cannot be found.
da846919	2018-06-17T09:30:05	[base] Add tracing for `FT_Bitmap_Blend'. * include/freetype/internal/fttrace.h (trace_bitmap): New enumeration. * src/base/ftbitmap.c (FT_COMPONENT): Define. (FT_Bitmap_Blend): Add `FT_TRACE5' calls.
e361cc6a	2018-06-17T09:13:37	s/trace_bitmap/trace_checksum/. * include/freetype/internal/fttrace.h: s/bitmap/checksum/. * src/base/ftobjs.c (FT_COMPONENT): s/trace_bitmap/trace_checksum/. Adjust code.

Sort entries.
54b332aa	2018-06-13T08:46:27	[sfnt] Separate `CPAL' and `COLR' table handling. Later on we want to support the `SVG' table also, which needs `CPAL' (but not `COLR'). * include/freetype/internal/sfnt.h (SFNT_Interface): Add `load_cpal' and `free_cpal' fields. (FT_DEFINE_SFNT_INTERFACE): Updated. * include/freetype/internal/tttypes.h (TT_FaceRec): Replace `colr_and_cpal' fields with `cpal' and `colr'. * src/sfnt/sfdriver.c (sfnt_interface): Updated. * src/sfnt/sfobjs.c (sfnt_load_face, sfnt_done_face): Updated. * src/sfnt/ttcolr.c (Colr, Cpal): Add `table' field.

22d1be3f	2018-06-12T06:07:40	Finish CPAL/COLR support (4/4). * src/sfnt/ttcolr.c (tt_face_find_color): Removed. (tt_face_colr_blend_layer): Use `face->palette' instead of calling `tt_face_find_color'. Use and set text foreground color.
45145d34	2018-06-12T06:02:59	Finish CPAL/COLR support (3/4). * src/base/ftcolor.c: Include FT_INTERNAL_SFNT_H. (FT_Palette_Select, FT_Palette_Set_Foreground_Color): Implement functions.
b85d4e8f	2018-06-12T05:53:58	Finish CPAL/COLR support (2/4). * src/sfnt/ttcolr.c (tt_face_palette_set): New function. (tt_face_load_colr): Allocate `face->palette' and call `tt_face_palette_set'. Adjust return error code in case of error. * src/sfnt/ttcolr.h: Updated. * include/freetype/internal/sfnt.h (TT_Set_Palette_Func): New function type. (SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): Add it. * src/sfnt/sfdriver.c (sfnt_interface), src/sfnt/sfobjs.c (sfnt_done_face): Updated.

56be5f72	2018-06-10T06:59:39	* src/sfnt/ttcolr.c (tt_face_load_colr): Improve overflow checks.
50fda0be	2018-06-09T22:52:43	[raster] Deal with pitch sign earlier. * src/raster/ftraster.c (black_TWorker): Remove unused `traceG', s/bTarget/bOrigin/. (Render_Glyph): Set `ras.bOrigin' at the bottom-left corner. (Vertical_Sweep_Init, {Vertical,Horizontal}_Sweep_{Span,Drop}): Updated accordingly.
c412de52	2018-06-09T23:56:21	[sfnt] Read `CPAL' version 1 tables. * include/freetype/internal.tttypes.h: Include FT_COLOR_H.

8f1ed548	2018-06-07T02:48:48	[base] API for Harmony LCD rendering. This introduces `FT_Library_SetLcdGeometry' for setting up arbitrary LCD subpixel geometry including non-striped patterns. * src/base/ftlcdfil.c (FT_Library_SetLcdGeometry): New function. * include/freetype/ftlcdfil.h: Document it. * include/freetype/freetype.h: Minor. * include/freetype/ftchapters.h: Minor.
f87ced9d	2018-06-06T17:49:17	ftcolor.h: Redesign API. While going to implement it I noticed that I need access to most of the `CPAL' elements; I thus plan to add a `cpal' field to `TT_FaceRec', which makes most of the previously suggested API functions obsolete because the fields will be directly accessable.
172904ee	2018-06-06T13:29:09	Minor.
89d2f429	2018-06-06T16:53:54	[bdf, pcf] Removed deprecated FT_FACE_FLAG_FAST_GLYPHS flag. * src/bdf/bdfdrivr.c (BDF_Face_Init): Removed deprecated FT_FACE_FLAG_FAST_GLYPHS flag. * src/pcf/pcfread.c (pcf_load_font): Removed deprecated FT_FACE_FLAG_FAST_GLYPHS flag.

(ft_black_render): Compute CBox and reject glyphs larger than 0xFFFF x 0xFFFF. * src/smooth/ftgrays.c (gray_raster_render): Reject glyphs larger than 0xFFFF x 0xFFFF.
80ac3645	2018-06-03T18:31:58	* src/smooth/ftgrays.c (gray_convert_glyph): Remove unused variables.
02842872	2018-06-03T09:17:55	* src/tools/glnames.py (main): Emit header in `light' comment style.
ae248034	2018-06-02T21:42:44	[smooth] Attempt to mitigate bug #54019. The robust rendering of estra large glyphs came with unbearable cost. The old way of bisecting should fail but fail faster. * src/smooth/ftgrays.c (gray_convert_glyph): Switch back to bisecting in y-direction.
67994e82	2018-06-02T19:51:03	* src/truetype/ttinterp.c (Ins_MIRP): Use SUB_LONG; avoid FT_ABS. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8706
fab10b6f	2018-06-02T09:53:58	* src/autofit/afwarp.h: Use AF_CONFIG_OPTION_USE_WARPER (#54033).
125b8480	2018-05-31T10:49:05	* src/raster/ftraster.c (black_TWorker_): Remove `gTarget' field. This is no longer used.
0589f6e6	2018-05-31T00:34:38	[sfnt] Get colors from `CPAL' table in right order (#54015). * src/sfnt/ttcolr.c (tt_face_find_color): Fix it.
db7c4060	2018-05-30T21:21:19	ftcolor.h: Improve API design, fix typos (#54011, #54014). * include/freetype/ftcolor.h (FT_Palette_Get_Names): Replace with... (FT_Palette_Get_Name_IDs): ... this function. (FT_Palette_Get_Entry_Names): Replace with... (FT_Palette_Get_Entry_Name_IDs): ... this function s/FT_Palette_Set_Foreground_COlor/FT_Palette_Set_Foreground_Color/.
d45d4b97	2018-05-30T17:35:39	Beautify a3cfed5e87232c933bdc64f43e8ebebcfd18b41b. * src/autofit/afloader.c (af_loader_load_glyph): Move the initialisation and declaration of variables into the if-block.
a3cfed5e	2018-05-30T12:37:46	Fix pointer underflow. The declaration of `edge2' can be reached with `edge1 == NULL' and `axis->edges == 0' which results in undefined behaviour. * src/autofit/afloader.c (af_loader_load_glyph): Initialise `edge2' after checking `axis->num_edges > 1'. `edge1 != NULL' can be assumed.
ae2cd1b7	2018-05-30T09:34:57	Various minor color fixes. * include/freetype/config/ftheader.h (FT_COLOR_H): New macro. * include/freetype/internal/ftobjs.h (FT_Colr_Internal): Change type of `load_flags' to `FT_Int32'. * include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func): Change type of `idx' to `FT_UInt'.

(tt_face_find_color, tt_face_colr_blend_layer): Change type of `color_index' to `FT_UInt'. Fix signedness and type issues. * src/sfnt/ttcolr.h: Updated.
51fee655	2018-05-25T22:16:11	[docmaker] Fix missing `Defined in (...)' under Windows/Cygwin. This platform uses backslashes for paths, which docmaker didn't understand correctly. * src/tools/docmaker/tohtml.py (HtmlFormatter::blockEnter): Use `os.path.normpath' to normalize the path for the platform being used.
7b73cb07	2018-05-24T22:38:24	[smooth] Formalize Harmony LCD rendering. This generalizes magic outline shifts that make Harmony LCD rendering work in terms of precise two-dimensional RGB subpixel positions. These coordinates are now set in time of the `smooth' module initialization and later used to shift a glyph outline for rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same coordinates. The letter, however, rotates them before using. The LCD bitmap padding is also calculated using these coordinates. * include/freetype/internal/ftobjs.h (FT_LibraryRec): New array field `lcd_geometry'. * src/base/ftlcdfil.c (ft_lcd_padding): Reworked. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Updated accordingly. * src/smooth/ftsmooth.c [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING] (ft_smooth_init): Initialize `lcd_geometry'. (ft_smooth_render_generic): Formalize outline shifts.
3360ca58	2018-05-22T09:06:24	[truetype] Reject elements of composites with invalid glyph indices. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8413 * src/truetype/ttgload.c (TT_Load_Composite_Glyph): Implement it.
3c99016f	2018-05-22T07:53:49	* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Trace # of points.
93363cd7	2018-05-20T22:50:00	* include/freetype/ftcolor.h: New file. This is an interface to the `CPAL' OpenType table. No implementation yet.
2f218a4c	2018-05-18T08:57:30	* include/freetype/internal/ftcalc.h (FT_MSB): Verified `_MSC_VER'. Actually `_BitScanReverse' is available since VS2005.
840b8443	2018-05-18T10:57:51	* include/freetype/internal/ftcalc.h (FT_MSB): Use `_MSC_VER' value. Older VC versions don't provide `_BitScanReverse'. We test for VC 2013. Reported by John Emmas <john@creativepost.co.uk>.
3331b84f	2018-05-18T07:19:57	Minor comment fixes.
2cac1c35	2018-05-17T19:40:44	s/inline/__inline/ for MSVC. Reported by John Emmas <john@creativepost.co.uk>. * include/freetype/internal/ftcalc.h (FT_MSB) [_MSC_VER]: Do it.
583dabf2	2018-05-16T20:37:43	Add function `FT_Get_GlyphLayers' to access `COLR' table data. * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec): Move this structure to... * include/freetype/freetype.h (FT_Glyph_LayerRec): ... this header file. (FT_Glyph_Layer): New typedef. Update code to use it where appropriate. * src/base/ftobjs.c (FT_Get_GlyphLayers): New function.
f1458d2e	2018-05-15T21:47:18	[base] Fix mono bitmap presetting (#53896). It is rather fundamental to set monochrome bitmap based on rounded CBox because the b/w rasterizer turns on pixels when their centers are inside the glyph outline. The dropout control is unpredictable and can distort narrow glyphs if the bitmap is too wide. Reported by Chris Liddell. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): If BBox boundaries are too close, adjust them before rounding.
49c5e24a	2018-05-15T21:55:28	[psaux] Fix compiler warning (#53915). * src/psaux/psft.c (cf2_freeT1SeacComponent): Do it.
befee112	2018-05-15T17:01:22	[sfnt] Fix memory leak in handling `COLR' data. * src/truetype/ttgload.c (TT_Load_Glyph): Free old `layers' array before reassigning allocated memory. Only allocate `color_layers' if we don't have one already.
2dd20916	2018-05-15T09:05:53	[sfnt] If `COLR' is present, don't assume that all glyphs use it. * src/sfnt/ttcolr.c (tt_face_load_colr_layers): Return FT_Err_Ok if current glyph is not a `COLR' base glyph. * src/truetype/ttgload.c (TT_Load_Glyph): Don't allocate `color_layers' if there are no color layers.
06820637	2018-05-14T09:45:16	* src/base/ftobjs.c (FT_Load_Glyph): Fix signature of `pixel_modes'.
c5a8a535	2018-05-14T09:42:20	Provide dummy functions if `TT_CONFIG_OPTION_SFNT_NAMES' is not set. * src/base/ftsnames.c [!TT_CONFIG_OPTION_SFNT_NAMES]: Implement it.
1b2abda9	2018-05-13T10:58:49	* src/base/ftobjs.c (FT_Load_Glyph): Improve tracing.
f04d8175	2018-05-13T03:25:09	[sfnt] Preliminary support of coloured layer outlines. This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS. There are still some issues with metrics; additionally, an API to fetch color layers is missing. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_OPTION_COLOR_LAYERS): New macro. * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec, FT_Colr_InternalRec): New structures. (FT_Slot_InternalRec): Add `color_layers' field. * include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func, TT_Blend_Colr_Func): New function types. (SFNT_Interface): Add `load_colr', `free_colr', `load_colr_layer', and `colr_blend' fields. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `colr_and_cpal' field. * include/freetype/internal/tttags. (TTAG_COLR, TTAG_CPAL): New macros. * src/sfnt/ttcolr.c, src/sfnt/ttcolr.h: New files. * src/base/ftobjs.c (ft_glyphslot_done, FT_Render_Glyph_Internal): Handle glyph color layers. * src/sfnt/Jamfile (_sources), src/sfnt/rules.mk (SFNT_DRV_SRC): Add `ttcolr.c'. * src/sfnt/sfdriver.c: Include `ttcolr.h'. (PUT_COLOR_LAYERS): New macro. Update call to `FT_DEFINE_SFNT_INTERFACE'. * src/sfnt/sfnt.c: Include `ttcolr.c'. * src/sfnt/sfobjs.c (sfnt_load_face): Load `COLR' and `CPAL' tables. (sfnt_done_face): Updated. * src/truetype/ttgload.c (TT_Load_Glyph): Handle color layers.
84eebf48	2018-05-12T06:16:46	Use MS VC++'s _BitScanReverse to calculate MSB (patch #9636). * include/freetype/internal/ftcalc.h (FT_MSB) [_MSC_VER]: Implement it.
9e345c91	2018-05-10T10:10:43	Further fix to visibility flag testing with Solaris Studio compilers. AC_COMPILE_IFELSE only tries to compile a `.c' to a `.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them. Tested on Solaris 11.4 beta with compiler versions: Sun Studio 8 (Sun C 5.5) Sun Studio 10 (Sun C 5.7) Sun Studio 11 (Sun C 5.8) Sun Studio 12 (Sun C 5.9) Sun Studio 12.1 (Sun C 5.10) Oracle Solaris Studio 12.2 (Sun C 5.11) Oracle Solaris Studio 12.3 (Sun C 5.12) Oracle Solaris Studio 12.4 (Sun C 5.13) Oracle Developer Studio 12.5 (Sun C 5.14) Oracle Developer Studio 12.6 (Sun C 5.15) gcc 5.5.0 gcc 7.3.0 and verified the libfreetype.so.6 generated by each of those compilers exported the same set of symbols. * builds/unix/configure.raw: Implement it.

029721d6	2018-04-07T21:34:24	Modernize CMake build. * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive modernization measures. * .gitignore: Add build/, as that's the example directory used in CMakeLists.txt. This brings up the minimum required CMake version to 2.8.12. The installation paths follow the GNU defaults now, e.g. installing on a 64 bit host will place binaries into the lib64/ folder on e.g. Fedora. Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC). CMake will no longer look for a C++ compiler. Library and .so version now match the Autotools build. Comments in the build file and informational messages now use platform agnostic example commands. ftoption.h and ftconfig.h are written directly without a redundant `-new' copy. External dependencies are expressed as option()s and will turn up as such in cmake-gui. Internal: Properties such as dependencies and include directories are now privately set on the freetype library instead of globally. The CPack definitions have been cleaned up, the `make dist' has been removed. Source packages generated with CPack don't contain Autotools files and aren't used by the maintainters anyway. On Windows, src/base/ftver.rc is compiled to decorate the library with version and copyright information. A pkg-config file is now generated and installed.

[sfnt] Preliminary support of coloured layer outlines. This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

Further fix to visibility flag testing with Solaris Studio compilers. AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them. Tested on Solaris 11.4 beta with compiler versions: Sun Studio 8 (Sun C 5.5) Sun Studio 10 (Sun C 5.7) Sun Studio 11 (Sun C 5.8) Sun Studio 12 (Sun C 5.9) Sun Studio 12.1 (Sun C 5.10) Oracle Solaris Studio 12.2 (Sun C 5.11) Oracle Solaris Studio 12.3 (Sun C 5.12) Oracle Solaris Studio 12.4 (Sun C 5.13) Oracle Developer Studio 12.5 (Sun C 5.14) Oracle Developer Studio 12.6 (Sun C 5.15) gcc 5.5.0 gcc 7.3.0 and verified the libfreetype.so.6 generated by each of those compilers exported the same set of symbols. * builds/unix/configure.raw: Implement it.

Modernize CMake build. * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive modernization measures. * .gitignore: Add build/, as that's the example directory used in CMakeLists.txt. This brings up the minimum required CMake version to 2.8.12. The installation paths follow the GNU defaults now, e.g. installing on a 64 bit host will place binaries into the lib64/ folder on e.g. Fedora. Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC). CMake will no longer look for a C++ compiler. Library and .so version now match the Autotools build. Comments in the build file and informational messages now use platform agnostic example commands. ftoption.h and ftconfig.h are written directly without a redundant `-new' copy. External dependencies are expressed as option()s and will turn up as such in cmake-gui. Internal: Properties such as dependencies and include directories are now privately set on the freetype library instead of globally. The CPack definitions have been cleaned up, the `make dist' has been removed. Source packages generated with CPack don't contain Autotools files and aren't used by the maintainters anyway. On Windows, src/base/ftver.rc is compiled to decorate the library with version and copyright information. A pkg-config file is now generated and installed.

* builds/toplevel.mk (work): Use $(SEP). This fixes the `make refdoc' using Cygwin: $(CAT) is `type' on this platform, and this program only understands backslashes in paths. Reported by Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com>.

* CMakeLists.txt [win32]: Allow MSVC DLL builds (#53287). Do not limit DLL builds to MinGW, since we already have `__declspec(dllexport)' directives in `ftconfig.h'. Also suppress more warnings for POSIX functions.
