Check overflow. * src/base/ftoutln.c (SCALED): Correctly handle left-shift of negative values. * src/bdf/bdf.h (_bdf_glyph_modified, _bdf_set_glyph_modified, _bdf_clear_glyph_modified): Use unsigned long constant. * src/bdf/bdfdrivr.c (BDF_Size_Select, BDF_Glyph_Load): Don't left-shift values that can be negative. * src/pcf/pcfdrivr.c (PCF_Size_Select, PCF_Glyph_Load): Don't left-shift values that can be negative. * src/raster/ftraster.c (SCALED): Correctly handle left-shift of negative values. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Don't left-shift values that can be negative. * src/truetype/ttgload.c (TT_Load_Composite_Glyph, compute_glyph_metrics, load_sbit_image): Don't left-shift values that can be negative.
f9be567f	2015-07-09T15:10:31	Better support of user-supplied C++ namespaces. See http://lists.nongnu.org/archive/html/freetype-devel/2015-07/msg00008.html for a rationale. * src/autofit/afpic.h, src/base/basepic.h, src/cff/cffpic.h, src/pshinter/pshpic.h, src/psnames/pspic.h, src/raster/rastpic.h, src/sfnt/sfntpic.h, src/smooth/ftspic.h, src/truetype/ttpic.h (FT_BEGIN_HEADER, FT_END_HEADER): Move macro calls to not enclose header files that contain FT_{BEGIN,END}_HEADER macros by themselves. * src/autofit/aftypes.h [FT_DEBUG_AUTOFIT]: Include FT_CONFIG_STANDARD_LIBRARY_H earlier. * src/truetype/ttpic.h: Include FT_INTERNL_PIC_H.
392cf22f	2015-06-25T13:04:57	Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated. Update creation of `ftconfig.h'. Install generated `ftconfig.h'. * Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. * builds/unix/configure.raw: Don't check for `rmdir'. * builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable according to the autoconf info manual. * builds/unix/install.mk (install, uninstall, distclean_project_unix): Update and simplify. * builds/wince/, builds/windows/: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/*: Updated.
8502c98b	2015-06-22T06:35:23	Fix Savannah bug #45097. We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include). After this commit, only `ft2build.h' stays in the compiler's include path. No visible changes for the user who follows the standard FreeType header inclusion rules. * include/: Move to ... include/freetype2/: This directory, except `ft2build.h'. CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/install.mk (install, uninstall), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. Emit -I directory only if it is not `/usr/include'. * builds/wince/, builds/windows/: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/*: Updated.
31d97df9	2015-06-21T19:12:12	Make Jam support work again. This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also. (DEFINES): Replace with... (CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.
d1ade6d1	2015-06-02T11:44:52	[raster] Add more tracing. * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define. (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span, Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
851e8151	2015-03-01T19:27:09	Various compiler warning fixes for `make multi'. * src/autofit/afcjk.c (af_cjk_hints_compute_blue_edges), src/autofit/aflatin.c (af_latin_hint_compute_blue_edges, af_latin_hint_edges), src/autofit/aflatin2.c (af_latin2_hints_compute_blue_edges, af_latin2_hint_edges): Declare as `static'. * src/cache/ftccmap.c (FTC_CMAP_QUERY_HASH, FTC_CMAP_NODE_HASH): Removed. Unused. * src/cache/ftcimage.c: Include FT_INTERNAL_OBJECTS_H. * src/cache/ftcmanag.c (FTC_LRU_GET_MANAGER): Removed. Unused. * src/cff/cf2intrp.c: Include `cf2intrp.h'. * src/cff/cffdrivr.c (PAIR_TAG): Removed. Unused. * src/gzip/ftgzip.c (NO_DUMMY_DECL): Removed.

Unused. * src/truetype/ttsubpix.c (is_member_of_family_class, is_member_of_style_class): Declare as `static'. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Declare as `static'. * src/type1/t1load.c (mm_axis_unmap, mm_weights_unmap): Declare as `static'. (T1_FIELD_COUNT): Removed. Unused. * src/type1/t1parse.h (T1_Done_Table): Removed. Unused. * src/type42/t42parse.c (T1_Done_Table): Removed. Unused.
4d1f7af1	2015-02-23T07:04:36	[smooth, raster] Re-enable standalone compilation. * src/raster/ftraster.c (FT_RENDER_POOL_SIZE, FT_MAX) [_STANDALONE_]: Define macros. * src/smooth/ftgrays.c (FT_RENDER_POOL_SIZE, FT_MAX, FT_ABS, FT_HYPOT) [_STANDALONE_]: Define macros.
a974e9ac	2015-02-22T21:02:13	* src/raster/ftraster.c: Use the file's typedefs everywhere.
ca96fe01	2015-02-22T20:05:04	[raster] Signedness fixes. * src/raster/ftraster.c, src/raster/ftrend1.c: Apply.
264b5e46	2015-01-23T21:23:55	[raster] Handle `FT_RASTER_FLAG_AA' correctly. This fixes a breakage caused by the commit `[raster] Remove 5-level gray AA mode from monochrome rasterizer.'. Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de> and octoploid <octoploid@yandex.com>. * src/raster/ftraster.c (ft_black_render): Handle `FT_RASTER_FLAG_AA'. * src/raster/ftrend1.c (ft_raster1_render): Remove gray AA mode remnants.
942aa5ff	2015-01-18T07:29:48	[raster] Fix Savannah bug #44022. Add fallback for glyphs with degenerate bounding boxes. If a glyph has only one very narrow feature, the bbox can end up with either the width or height of the bbox being 0, in which case no raster memory is allocated and no attempt is made to render the glyph. This is less than ideal when the drop-out compensation in the rendering code would actually result in the glyph being rendered. This problem can be observed with the `I' glyph (gid 47) in the Autodesk RomanS TrueType font. * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either dimension is zero to explicitly round up/down (instead of simply round).
f57fc59e	2015-01-17T20:41:43	Run `src/tools/update-copyright'.
c242fe41	2015-01-14T18:48:14	[raster] Fix uninitialized memory access. Apparently `ras.cProfile' might be uninitialized. This will be the case if `ras.top == ras.cProfile->offset', as can be seen in `End_Profile'. The overshoot code introduced in a change `Fix B/W rasterization of subglyphs with different drop-out modes.' (from 2009-06-18) violated this, accessing `ras.cProfile->flags' unconditionally just before calling `End_Profile' (which then detected that `cProfile' is uninitialized and didn't touch it). This was harmless, and was not detected by valgrind before because the objects were allocated on the `raster_pool', which was always initialized. With recent change to allocate raster buffers on the stack, valgrind now reported this invalid access. * src/raster/ftraster.c (Convert_Glyph): Don't access an uninitialized `cProfile'.
a773c304	2015-01-14T18:16:20	[raster] Allocate render pool for mono rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the monochrome rasterizer. * src/raster/ftraster.c (black_TRaster): Remove `buffer', `buffer_size', and `worker' members. (ft_black_render): Create `buffer' locally. (ft_black_reset): Updated.
8dc86358	2015-01-14T18:06:22	[raster] Remove 5-level gray AA mode from monochrome rasterizer. It was off by default and couldn't be turned on at runtime. And the smooth rasterizer superceded it over ten years ago. No point in keeping. Comments suggested that it was there for compatibility with FreeType 1. 550 lines down. * src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING, RASTER_GRAY_LINES): Remove macros and all associated code. (black_TWorker): Remove `gray_min_x' and `gray_max_x'. (black_TRaster): Remove `grays' and `gray_width'. (Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop, ft_black_render): Updated. * src/raster/ftrend1.c (ft_raster1_render): Simplify code. (ft_raster5_renderer_class): Removed.
36d03c9f	2015-01-12T11:26:30	Fix Savannah bug #43976. Assure that FreeType's internal include directories are found before `CPPFLAGS' (which might be set by the user in the environment), and `CPPFLAGS' before `CFLAGS'. * builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'. (FT_COMPILE): Make this a special variable for compiling only the files handled in `freetype.mk'. (.c.$O): Removed, unused. * src//rules.mk (_COMPILE): Fix order of include directories.
3e86711e	2014-11-25T09:01:07	[Savannah bug #43682] Adjust some renderer callbacks. * src/raster/ftraster.c (ft_black_set_mode): Change return type to `int' to stay in sync with `FT_Renderer_SetModeFunc' prototype. * src/smooth/ftgrays.c (gray_raster_set_mode): New dummy function for orthogonality. (ft_grays_raster): Use it.
b3500af7	2014-11-19T21:28:21	Change some fields in `FT_Bitmap' to unsigned type. This doesn't break ABI. * include/ftimage.h (FT_Bitmap): Make `rows', `width', `num_grays', `pixel_mode', and `palette_mode' unsigned types. * src/base/ftbitmap.c: Updated. (FT_Bitmap_Copy): Fix casts. * src/cache/ftcsbits.c, src/raster/ftraster.c, src/sfnt/pngshim.c: Updated.
426f0e04	2014-04-24T07:13:31	Minor.
f193637f	2014-04-23T08:22:33	* src/raster/ftraster.c (Vertical_Sweep_Span): Use drop-out mode. This spot has been missed while introducing support for various drop-out modes years ago (including no drop-out mode, which this commit fixes). Problem reported by Patrick Thomas <pthomas505@gmail.com>.
7be2a94a	2014-02-08T13:55:38	Fix clang static analyzer and compiler warnings. * src/autofit/afhints.c (af_glyph_hints_align_weak_points), src/autofit/afloader (af_loader_load_g) <FT_GLYPH_FORMAT_COMPOSITE>, src/base/ftcalc.c (FT_MSB), src/base/ftoutln.c (FT_Outline_Decompose), src/bdf/bdfdrivr.c (bdf_interpret_style), src/cff/cffparse.c (cff_parse_integer), src/cid/cidparse.c (cid_parser_new), src/pfr/pfrload.c (pfr_phy_font_load), src/raster/ftraster.c (Decompose_Curve), src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/ttcmap.c (tt_cmap12_next, tt_cmap13_next), src/smooth/ftgrays.c (gray_hline): Remove dead code. * src/autofit/afmodule.c (af_property_get_face_globals, af_property_set, af_property_get), src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Make functions static. * src/base/ftobjs.c (ft_remove_renderer): Protect against library == NULL. (ft_property_do): Make function static. * src/base/ftrfork.c: Include `ftbase.h'. * src/sfnt/ttsbit.c (tt_face_load_sbix_image) [!FT_CONFIG_OPTION_USE_PNG], src/type1/t1gload.c (T1_Compute_Max_Advance): Avoid compiler warning. * src/truetype/ttinterp.c (TT_New_Context): Reduce scope of variable.
fae38207	2013-11-13T08:55:46	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.
c06889eb	2013-06-12T10:58:06	More compiler warning fixes. /: Use cast to `FT_Bool' (or `Bool') where appropriate.
badf3178	2013-06-06T09:16:38	Next round of compiler fixes. * builds/win32/ftdebug.c, builds/wince/ftdebug.c (ft_debug_init): Add proper cast. * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Fix cast. * include/freetype/internal/ftstream.h: Decorate stream and frame macros with `FT_Long' and `FT_ULong' as appropriate. * src/base/ftrfork.c (raccess_guess_darwin_hfsplus, raccess_guess_darwin_newvfs): Use cast. * src/bdf/bdflib.c (_bdf_set_default_spacing): Use cast. * src/cache/ftcmanag.c (FTC_Manager_Check): Fix cast. * src/cache/ftcmanag.h (FTC_ManagerRec): Ditto. * src/cff/cf2arrst.c (cf2_arrstack_setNum_Elements): Use cast. * src/cff/cf2ft.c (cf2_freeSeacComponent): Ditto. * src/cff/cffobjs.c (remove_subset_prefix, remove_style): Ditto. * src/cid/cidparse.c (cid_parser_new): Use cast. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Use cast. * src/psaux/psobjs.c (reallocate_t1_table): Fix argument type. * src/raster/ftraster.c (ft_black_reset): Use cast. * src/truetype/ttgxvar.c (FT_Stream_FTell): Use cast. (ALL_POINTS): Fix cast. * src/type1/t1driver.c (t1_ps_get_font_value): Add casts. * src/type1/t1parse.c (T1_Get_Private_Dict): Add cast.
8d8508e4	2013-06-04T13:09:01	Missed some cppcheck items.
dc624ca4	2013-06-04T10:30:48	Apply fixes for cppcheck nitpicks. http://cppcheck.sourceforge.net/ Note that the current version heavily chokes on FreeType, delivering even wrong results. I will report those issues to the cppcheck team so that a newer version gives improved results hopefully. / Improve variable scopes. / Remove redundant initializations which get overwritten. * src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable): Remove unused variable. * src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero. * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate): Remove functionless code. * src/tools/ftrandom.c (main): Fix memory leak.
073a0e29	2013-05-05T10:41:20	[raster] Fix clang issues. Fix suggested by <octoploid@yandex.com>. * src/raster/ftraster.c (ULong): New typedef. (SCALED): Add proper cast.
762bf19a	2013-03-24T08:37:12	Typo.
5ea06ce0	2013-03-17T08:14:46	Whitespace.
706fc833	2013-03-17T08:09:17	Remove dead code. * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init) src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.
e3c93015	2013-03-14T11:21:17	/: Use FT_Err_Ok only. This is a purely mechanical conversion.
059bc335	2013-03-14T10:27:35	/: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
328aa3b2	2012-08-27T11:23:41	[FT_CONFIG_OPTION_PIC] Fix g++ 4.6.2 compiler warnings. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER), include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE), include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC1, FT_DEFINE_SERVICEDESCREC2, FT_DEFINE_SERVICEDESCREC3, FT_DEFINE_SERVICEDESCREC4, FT_DEFINE_SERVICEDESCREC5, FT_DEFINE_SERVICEDESCREC6), src/autofit/afpic.c (autofit_module_class_pic_init), src/base/basepic.c (ft_base_pic_init), src/base/ftinit.c (ft_create_default_module_classes), src/cff/cffparse.c (FT_Create_Class_cff_field_handlers), src/cff/cffpic.c (cff_driver_class_pic_init), src/pshinter/pshpic.c (pshinter_module_class_pic_init), src/psnames/pspic.c (psnames_module_class_pic_init), src/raster/rastpic.c (ft_raster1_renderer_class_pic_init), src/sfnt/sfntpic.c (sfnt_module_class_pic_init), src/sfnt/ttcmap.c (FT_Create_Class_tt_cmap_classes), src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init), src/truetype/ttpic.c (tt_driver_class_pic_init): Initialize allocation variable.

3c966818	2012-01-15T23:35:31	Fix redundant declaration warning in PIC mode. Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were designed to declare xxx_pic_{free,init} by themselves. Because these macros are used at the end of the module interface (e.g. ttdriver.c) and the wrapper source to build a module as a single object (e.g. truetype.c) includes the PIC file (e.g. ttpic.c) before the module interface, these macros are expanded AFTER xxx_pic_{free,init} body when the modules are built as single object. The declaration after the implementation causes the redundant declaration warnings, so the declarations are moved to module PIC headers (e.g. ttpic.h). Separating to other header files are needed for multi build. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): Remove class_##_pic_free and class_##_pic_init declarations. * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE): Ditto. * src/base/basepic.h: Insert a comment and fix coding style. * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, init}. * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, init}. * src/psnames/pspic.h: Declare psnames_module_class_pic_{free, init}. * src/raster/rastpic.h: Declare ft_raster{1,5}_renderer_class_pic_{free,init} * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. * src/smooth/ftspic.h: Declare ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.

46c371c2	2010-10-25T00:14:13	Replace "%lx" for memory address by "%p", LLP64 platforms. On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover the memory address (64-bit). Also the casts from the pointer type to long int should be removed to preserve the address correctly. * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".

72271140	2009-06-18T15:42:52	Fix B/W rasterization of subglyphs with different drop-out modes. Normally, the SCANMODE instruction (if present) to set the drop-out mode in a TrueType font is located in the `prep' table only and thus valid for all glyphs. However, there are fonts like `pala.ttf' which additionally contain this instruction in the hinting code of some glyphs (but not all). As a result it can happen that a composite glyph needs multiple drop-out modes for its subglyphs since the rendering state gets reset for each subglyph. FreeType collects the hinted outlines from all subglyphs, then it sends the data to the rasterizer. It also sends the drop-out mode -- after hinting has been applied -- and here is the error: It sends the drop-out mode of the last subglyph only; drop-out modes of all other subglyphs are lost. This patch fixes the problem; it adds a second, alternative mechanism to pass the drop-out mode: For each contour, the rasterizer now checks the first `tags' array element. If bit 2 is set, bits 5-7 contain the contour's drop-out mode, overriding the global drop-out mode. * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro. * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in `tags[0]'. * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom): Use bits 3-5 instead of 0-2. (New_Profile): Set the drop-out mode in the profile's `flags' field. (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if necessary. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out mode.
42206ad8	2009-06-16T15:14:21	Improve scan conversion rules 4 and 6. Two new constraints are introduced to better identify a `stub' -- a concept which is only vaguely described in the OpenType specification. The old code was too rigorous and suppressed more pixel than it should. . The intersection of the two profiles with the scanline is less than a half pixel. Code related to this was already present in the sources but has been commented out. . The endpoint of the original contour forming a profile has a distance (`overshoot') less than half a pixel to the scanline. Note that the two additional conditions fix almost all differences to the Windows rasterizer, but some problematic cases remain. * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New macros for the `flags' field in the `TProfile' structure. (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros. (New_Profile, End_Profile): Pass overshoot flag as an argument and set it accordingly. Update callers. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new constraints.
0409ef32	2009-06-11T17:32:31	Increase precision for B/W rasterizer. * src/raster/ftraster.c (Set_High_Precision): Add two more bits to the precision. This corrects rendering of some small glyphs, for example, glyph `xi' in verdana.ttf at 13 ppem. Testing with ftbench on my GNU/Linux box I don't see a performance degradation.
2f2b780e	2009-06-07T08:29:30	Simplify math. Suggested by Alexei Podtelezhnikov <apodtele@gmail.com>. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Do it.

Problem reported by Krzysztof Kotlenga <pocek@users.sf.net>. * src/raster/raster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): For smart drop-out mode, if intersections are equally distant relative to next pixel center, select the left pixel, not the right one.
05609509	2009-04-05T18:16:13	Position Independent Code (PIC) support in raster renderer. * src/raster/ftrend1.h declare ft_raster1_renderer_class and ft_raster5_renderer_class using macros from ftrender.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/smooth/ftrend1.c when FT_CONFIG_OPTION_PIC is defined ft_raster1_renderer_class and ft_raster5_renderer_class structs will have functions to init or create and destroy them instead of being allocated in the global scope. Macros will be used from rastpic.h in order to access ft_standard_raster from the pic_container (allocated in ftraster.c). In ft_raster1_render when PIC is enabled, the last letter of module_name is used to verfy the renderer class rather than the class pointer. * src/raster/ftraster.c when FT_CONFIG_OPTION_PIC is defined ft_standard_raster struct will have function to init it instead of being allocated in the global scope. New Files: * src/raster/rastpic.h declare struct to hold PIC globals for raster renderer and macros to access them. * src/raster/rastpic.c implement functions to allocate, destroy and initialize PIC globals for raster renderer. * src/raster/raster.c add new file to build: rastpic.c. * src/raster/jamfile add new files to FT2_MULTI build: rastpic.c.

ce33a312	2008-12-21T10:29:30	FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.) Patch from Savannah bug #25133. * src/base/ftinit.c (FT_USE_MODULE): Include variable type. * builds/amiga/include/freetype/config/ftmodule.h, include/freetype/config/ftmodule.h, */module.mk: Updated to declare pass correct types to FT_USE_MODULE.

Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated.

Fix Savannah bug #45097. We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include). After this commit, only `ft2build.h' stays in the compiler's include path. No visible changes for the user who follows the standard FreeType header inclusion rules. * include/*: Move to ... * include/freetype2/*: This directory, except `ft2build.h'. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/install.mk (install, uninstall), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated.

[raster] Fix Savannah bug #44022. Add fallback for glyphs with degenerate bounding boxes. If a glyph has only one very narrow feature, the bbox can end up with either the width or height of the bbox being 0, in which case no raster memory is allocated and no attempt is made to render the glyph. This is less than ideal when the drop-out compensation in the rendering code would actually result in the glyph being rendered. This problem can be observed with the `I' glyph (gid 47) in the Autodesk RomanS TrueType font. * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either dimension is zero to explicitly round up/down (instead of simply round).

[raster] Fix uninitialized memory access. Apparently `ras.cProfile' might be uninitialized. This will be the case if `ras.top == ras.cProfile->offset', as can be seen in `End_Profile'. The overshoot code introduced in a change `Fix B/W rasterization of subglyphs with different drop-out modes.' (from 2009-06-18) violated this, accessing `ras.cProfile->flags' unconditionally just before calling `End_Profile' (which then detected that `cProfile' is uninitialized and didn't touch it). This was harmless, and was not detected by valgrind before because the objects were allocated on the `raster_pool', which was always initialized. With recent change to allocate raster buffers on the stack, valgrind now reported this invalid access. * src/raster/ftraster.c (Convert_Glyph): Don't access an uninitialized `cProfile'.

Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the monochrome rasterizer. * src/raster/ftraster.c (black_TRaster): Remove `buffer', `buffer_size', and `worker' members. (ft_black_render): Create `buffer' locally. (ft_black_reset): Updated.

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.

Fix redundant declaration warning in PIC mode. Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were designed to declare xxx_pic_{free,init} by themselves. Because these macros are used at the end of the module interface (e.g. ttdriver.c) and the wrapper source to build a module as a single object (e.g. truetype.c) includes the PIC file (e.g. ttpic.c) before the module interface, these macros are expanded AFTER xxx_pic_{free,init} body when the modules are built as single object. The declaration after the implementation causes the redundant declaration warnings, so the declarations are moved to module PIC headers (e.g. ttpic.h). Separating to other header files are needed for multi build. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): Remove class_##_pic_free and class_##_pic_init declarations. * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE): Ditto. * src/base/basepic.h: Insert a comment and fix coding style. * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, init}. * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, init}. * src/psnames/pspic.h: Declare psnames_module_class_pic_{free, init}. * src/raster/rastpic.h: Declare ft_raster{1,5}_renderer_class_pic_{free,init} * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. * src/smooth/ftspic.h: Declare ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.

[raster] Make bbox handling the same as with Microsoft's rasterizer. Right before B/W rasterizing, the bbox gets simply rounded to integers. This fixes, for example, glyph `three' in font `Helvetica Neue LT Com 65 Medium' at 11ppem. Thanks to Greg Hitchcock who explained this behaviour. * src/raster/ftrend1.c (ft_raster1_render): Implement it.

[raster] Handle drop-outs at glyph borders according to Microsoft. If a drop-out rule would switch on a pixel outside of the glyph's bounding box, use the right (or top) pixel instead. This is an undocumented feature, but some fonts like `Helvetica Neue LT Com 65 Medium' heavily rely on it. Thanks to Greg Hitchcock who explained this behaviour. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement it.

Fix B/W rasterization of subglyphs with different drop-out modes. Normally, the SCANMODE instruction (if present) to set the drop-out mode in a TrueType font is located in the `prep' table only and thus valid for all glyphs. However, there are fonts like `pala.ttf' which additionally contain this instruction in the hinting code of some glyphs (but not all). As a result it can happen that a composite glyph needs multiple drop-out modes for its subglyphs since the rendering state gets reset for each subglyph. FreeType collects the hinted outlines from all subglyphs, then it sends the data to the rasterizer. It also sends the drop-out mode -- after hinting has been applied -- and here is the error: It sends the drop-out mode of the last subglyph only; drop-out modes of all other subglyphs are lost. This patch fixes the problem; it adds a second, alternative mechanism to pass the drop-out mode: For each contour, the rasterizer now checks the first `tags' array element. If bit 2 is set, bits 5-7 contain the contour's drop-out mode, overriding the global drop-out mode. * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro. * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in `tags[0]'. * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom): Use bits 3-5 instead of 0-2. (New_Profile): Set the drop-out mode in the profile's `flags' field. (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if necessary. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out mode.

Improve scan conversion rules 4 and 6. Two new constraints are introduced to better identify a `stub' -- a concept which is only vaguely described in the OpenType specification. The old code was too rigorous and suppressed more pixel than it should. . The intersection of the two profiles with the scanline is less than a half pixel. Code related to this was already present in the sources but has been commented out. . The endpoint of the original contour forming a profile has a distance (`overshoot') less than half a pixel to the scanline. Note that the two additional conditions fix almost all differences to the Windows rasterizer, but some problematic cases remain. * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New macros for the `flags' field in the `TProfile' structure. (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros. (New_Profile, End_Profile): Pass overshoot flag as an argument and set it accordingly. Update callers. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new constraints.

Position Independent Code (PIC) support in raster renderer. * src/raster/ftrend1.h declare ft_raster1_renderer_class and ft_raster5_renderer_class using macros from ftrender.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/smooth/ftrend1.c when FT_CONFIG_OPTION_PIC is defined ft_raster1_renderer_class and ft_raster5_renderer_class structs will have functions to init or create and destroy them instead of being allocated in the global scope. Macros will be used from rastpic.h in order to access ft_standard_raster from the pic_container (allocated in ftraster.c). In ft_raster1_render when PIC is enabled, the last letter of module_name is used to verfy the renderer class rather than the class pointer. * src/raster/ftraster.c when FT_CONFIG_OPTION_PIC is defined ft_standard_raster struct will have function to init it instead of being allocated in the global scope. New Files: * src/raster/rastpic.h declare struct to hold PIC globals for raster renderer and macros to access them. * src/raster/rastpic.c implement functions to allocate, destroy and initialize PIC globals for raster renderer. * src/raster/raster.c add new file to build: rastpic.c. * src/raster/jamfile add new files to FT2_MULTI build: rastpic.c.

FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.) Patch from Savannah bug #25133. * src/base/ftinit.c (FT_USE_MODULE): Include variable type. * builds/amiga/include/freetype/config/ftmodule.h, include/freetype/config/ftmodule.h, */module.mk: Updated to declare pass correct types to FT_USE_MODULE.
