Werner Lemberg 16586859 2020-06-13T21:15:45 Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
David Turner e1339133 2020-06-08T13:31:55 Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg 52aad9df 2015-09-29T12:38:11 [raster] Minor style fix.
Alexei Podtelezhnikov 5a6dc872 2015-09-04T23:14:46 [raster,smooth] Microoptimizations. * src/raster/ftraster.c (Insert_Y_Turn, Finalize_Profile_Table, Beziier_Up, ): Use do-while loops. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line, gray_convert_glyph): Ditto.
Werner Lemberg 6343ba22 2015-08-01T07:53:48 Fix some bugs found by clang's `-fsanitize=undefined' (#45661). * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Only accept positive values from header.

Werner Lemberg 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.
Werner Lemberg 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.

Behdad Esfahbod 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.
Werner Lemberg f57fc59e 2015-01-17T20:41:43 Run `src/tools/update-copyright'.
Behdad Esfahbod 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'.
Behdad Esfahbod 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.
Behdad Esfahbod 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 426f0e04 2014-04-24T07:13:31 Minor.
Werner Lemberg 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>.
Sean McBride 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.
Werner Lemberg 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.
Werner Lemberg c06889eb 2013-06-12T10:58:06 More compiler warning fixes. */*: Use cast to `FT_Bool' (or `Bool') where appropriate.
Werner Lemberg 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.

Werner Lemberg 8d8508e4 2013-06-04T13:09:01 Missed some cppcheck items.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 762bf19a 2013-03-24T08:37:12 Typo.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 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.

Werner Lemberg 0039d012 2011-01-14T19:44:29 [raster] Add undocumented drop-out rule to the other bbox side also. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement it.
Werner Lemberg c02485cb 2011-01-13T21:55:08 [raster] Reduce jitter value. This catches a rendering problem with glyph `x' from Tahoma at 10ppem. It seems that the increase of the precision in the change from 2009-06-11 makes a larger jitter value unnecessary. * src/raster/ftraster.c (Set_High_Precision): Implement it.
Werner Lemberg 29bc3105 2011-01-13T12:22:55 [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.
Werner Lemberg 6a96bbe2 2010-10-28T08:51:15 [ftraster] Minor fixes. Reported by Tom Bishop <wenlin@wenlin.com>. * src/raster/ftraster.c (ULong): Remove unused typedef. (TWorker): Remove unused variable `precision_mask'.
Werner Lemberg f0987abd 2010-10-28T08:33:28 [ftraster] Fix rendering. Problem reported by Tom Bishop <wenlin@wenlin.com>; see thread starting with http://lists.gnu.org/archive/html/freetype/2010-10/msg00049.html * src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv since the involved multiplication exceeds 32 bits.
suzuki toshiya 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". (End_Profile) Ditto. * src/truetype/ttinterp.c (Init_Context): Ditto.
Werner Lemberg 12cf0316 2010-08-29T11:02:24 [ftraster] Pacify compiler. * src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is not used.
Yuriy Kaminskiy c9de9cbd 2010-08-06T08:20:28 [raster] Fix valgrind warning. * src/raster/ftraster.c (Decompose_Curve) <default>: Access point[0] only if we don't hit `limit'.
Werner Lemberg c8f5b98b 2010-07-12T21:13:22 Remove C++ warnings. */*: Initialize pointers where necessary to make g++ happy.
Ken Sharp 7baeeafc 2010-04-05T11:19:38 Fix Savannah bug #29335. * src/raster/ftraster.c (Line_Up): Use slow multiplication to prevent overflow. This shouldn't have any serious impact on speed, however.
Chris Liddell 6c0d8814 2010-03-11T18:27:31 Fix Savannah bug #27442. * src/raster/ftraster.c (ft_black_reset): Fix `buffer_size'.
Werner Lemberg 766b822f 2009-09-12T23:15:17 [raster] Fix 5-levels grayscale output. This was broken since version 2.3.0. * src/raster/ftraster.c (count_table): Use pre-2.3.0 values (which were then computed dynamically). (Vertical_Gray_Sweep_Step): Updated. (ft_black_render): Initialize `worker->gray_lines' (problem found by valgrind). (FT_RASTER_OPTION_ANTI_ALIASING, DEBUG_RASTER): Dont' #undef, just comment out.
Werner Lemberg 0d02317f 2009-07-09T09:21:46 [ftraster] Make it compile again with -D_STANDALONE_. * src/raster/ftraster.c [_STANDALONE_]: Define FT_CONFIG_STANDARD_LIBRARY_H. Include `string.h'. Don't include `rastpic.h'. Define FT_DEFINE_RASTER_FUNCS.
Werner Lemberg 858abbed 2009-06-26T06:15:41 For warning messages, replace FT_ERROR with FT_TRACE0. FT_ERROR is now used only if a function produces a non-zero `error' value. Formatting, improving and harmonizing debug strings.

Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 90c699af 2009-06-05T10:37:15 Preparation for fixing scan conversion rules 4 and 6. * src/raster/ftraster.c (TFlow): Replace enumeration with... (Flow_Up): This macro. (TProfile): Replace `flow' member with `flags' bit field. Update all affected code.
Werner Lemberg cbdba615 2009-06-03T08:53:47 Typo, formatting.
Werner Lemberg 19fbc576 2009-05-22T09:20:25 Improve b/w rasterizer. 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.
Oran Agra 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.

Werner Lemberg 71b8f3f2 2008-07-04T07:22:06 * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one pixel, only check for dropouts if neither start nor end point lies on a pixel center. This fixes Savannah bug #23762.
Werner Lemberg a741c6f2 2008-06-27T06:58:48 * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Test for intersections which degenerate to a single point can be ignored; this has been confirmed by Greg Hitchcock from Microsoft.
