Alexei Podtelezhnikov 0417527d 2022-10-03T19:23:26 [autofit] Reset the face charmap directly. There is no need to validate the original charmap in `FT_Set_Charmap`. It can be reset directly. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Use direct assignment. * src/autofit/af{latin,cjk,indic}.c (af_latin_metrics_init): Ditto.
Alexei Podtelezhnikov ee72e285 2022-07-29T22:55:28 [autofit] Use unsigned accounting for hints. * src/autofit/afhints.h (AF_AxisHintsRec): Use unsigned types. * src/autofit/afhints.c (af_axis_hints_new_{segment,edge}, af_glyph_hints_get_num_segments, af_glyph_hints_get_segment_offset): Updated accordingly. * src/autofit/aflatin.c (af_cjk_hints_compute_edges): Ditto. * src/autofit/afcjk.c (af_cjk_hints_compute_edges): Ditto.

Werner Lemberg 5aa2a5c3 2022-01-07T06:41:36 [autofit, pshinter] Use `FT_OFFSET`. This avoids ``` runtime error: applying zero offset to null pointer ``` warnings of clang's undefined behaviour sanitizer. * src/autofit/afcjk.c (af_cjk_hints_link_segments, af_cjk_hints_compute_edges, af_cjk_hints_compute_blue_edges, af_cjk_hint_edges, af_cjk_align_edge_points): Do it. * src/autofit/afhints.c (af_glyph_hints_align_edge_points, af_glyph_hints_align_strong_points): Ditto. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hints_link_segments, af_latin_hints_compute_edges, af_latin_hints_compute_blue_edges, af_latin_hint_edges): Ditto. * src/pshinter/pshalgo.c (psh_hint_table_init): Ditto.
David Turner 2f11522a 2021-06-02T19:05:09 Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably nevery worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purpose.

Werner Lemberg a6adb256 2020-12-02T14:15:07 * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested).
Priyesh Kumar 53be1753 2020-07-28T07:33:40 Fix `-Wformat' compiler warnings. * src/*: Fix format specifiers. * builds/unix/ftsystem.c (FT_Stream_Open): Ditto.

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 a9af6914 2018-09-25T09:10:09 Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
Werner Lemberg a0dd16fb 2018-08-15T18:13:17 Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. */* (FT_COMPONENT): Updated.
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.

Alexei Podtelezhnikov a7f276a2 2017-05-15T00:25:37 [autofit] Make autohint warping NORMAL option. This moves warping option from LIGHT to NORMAL mode. This makes LIGHT truly void of hinting in x-direction, with left side bearing never changed and right side bearing only altered by advance rounding. Therefore, LIGHT is now ready to return fractional advance. As a NORMAL option, warping substitutes normal hinting. * src/autofit/afcjk.c (af_cjk_hints_apply): Updated. * src/autofit/aflatin.c (af_latin_hints_apply): Updated. * src/autofit/aflatin2.c (af_latin2_hints_apply): Updated. * src/autofit/afloader.c (af_loader_load_glyph): Handle warping phantom points as normal.
Werner Lemberg ba40054c 2017-05-02T12:32:19 [autofit] Remove `slight' auto-hint mode again. A poll on freetype-devel favoured changes directly applied to `light'. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT, FT_RENDER_MODE_SLIGHT): Removed. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2.c (af_latin2_hints_init): Revert change from 2017-04-22. * src/autofit/afloader.c (af_loader_load_glyph) Remove references to FT_RENDER_MODE_SLIGHT. [AF_CONFIG_OPTION_TT_SIZE_METRICS]: Enable TrueType-like metrics unconditionally. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Revert change from 2017-04-22. * src/base/ftobjs.c (FT_Load_Glyph): Revert change from 2017-04-22. * src/pshinter/pshalgo.c (ps_hints_apply): Revert change from 2017-04-22. * src/smooth/ftsmooth.c (ft_smooth_render): Revert change from 2017-04-22. * docs/CHANGES: Updated.
Werner Lemberg 5aa6716a 2017-04-22T13:27:21 Add new `slight' auto-hinting mode. This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backwards compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro. (FT_RENDER_MODE_SLIGHT): New render mode. * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add `autohint_mode' and `autohint_metrics' fields. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init): Updated. * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use `autohint_metrics'. (af_loader_load_glyph): s/internal/slot_internal/. Initialize `autohint_metrics' and `autohint_mode' depending on current auto-hint mode. Use `autohint_metrics'. Updated. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated. * src/base/ftobjs.c (FT_Load_Glyph): Updated. (FT_New_Size): Allocate `internal' object. * src/pshinter/pshalgo.c (ps_hints_apply): Updated. * src/smooth/ftsmooth.c (ft_smooth_render): Updated.
Alexei Podtelezhnikov 54b58097 2017-03-31T22:41:53 [autofit] Disable stem adjustment for `FT_LOAD_TARGET_LCD'. * include/freetype/freetype.h (FT_LOAD_TARGET_LCD): Document it. * src/autofit/afcjk.c (af_cjk_hints_init): Updated. * src/autofit/aflatin.c (af_latin_hints_init): Ditto. * src/autofit/aflatin2.c (af_latin2_hints_init): Ditto.

This improves rendering of scripts like Bengali or Devanagari. * src/autofit/afhints.c (af_axis_hints_new_edge): Add parameter to pass top-to-bottom hinting flag. This makes the function sort edges in descending vertical position. * src/autofit/afhints.c: Updated. * src/autofit/aflatin.c (af_latin_hints_compute_edges, af_latin_hint_edges): Use `top_to_bottom_hinting' flag. * src/autofit/afcjk.c (af_cjk_hints_compute_edges), src/autofit/aflatin2.c (af_latin2_hints_compute_edges): Updated.
Werner Lemberg 24aa9c66 2015-12-06T18:52:41 [autofit] Rewrite HarfBuzz interface to support character clusters. Scripts like Khmer have blue zones that can't be directly represented by Unicode characters. Instead, it is necessary to let HarfBuzz convert character clusters into proper glyph representation forms, then deriving the blue zone information from the resulting glyphs. * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by... * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new files, providing a new API to access HarfBuzz. The new API manages a HarfBuzz buffer with `af_shaper_buf_create' and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded string with function `af_shaper_get_cluster', and the resulting glyph data (indices, advance widths, vertical offsets) can be iteratively accessed with function `af_shaper_get_elem'. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/. * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.

Werner Lemberg f45c0bf9 2015-12-06T09:58:18 [autofit] Use string of standard characters. This is more flexible; additionally, it would allow character clusters. * src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated. (AF_ScriptClassRec): Replace `standard_char[123]' with `standard_charstring'. * src/autofit/afscript.h: Replace last three character arguments of the `SCRIPT' calls with a string parameter, holding the standard characters (in UTF-8 encoding) separated with spaces. * src/autofit/afglobal.c, src/autofit/afglobal.h, src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c (SCRIPT): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated.
Nikolaus Waxweiler 37c401ac 2015-11-02T09:32:26 [autofit] Add functions to get standard widths for writing systems. We need the computed standard horizontal and vertical widths for the emboldening calculation. This method provides a convenient way to extract it from writing-system-specific metrics structures, which all script definitions must implement. * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New function type. (AF_WritingSystemClassRec): New member `style_metrics_getstdw'. (AF_DEFINE_WRITING_SYSTEM_CLASS): Updated. * src/autofit/afcjk.c (af_cjk_get_standard_width): New function.

Werner Lemberg 98e510ee 2014-04-20T22:11:27 [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. (af_cjk_align_linked_edge): Add tracing message. * src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer used.
Werner Lemberg 71f53e12 2014-04-05T16:27:19 [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 hinting of slanted fonts (especially if the inner parts of serifs have non-horizontal `shoulders'), avoiding false stem links. * src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest stem width (if available) to compute better demerits for distances between stems. (af_latin_hints_detect_features): Pass stem width array and array size. (af_latin_metrics_init_widths): Updated to use original algorithm.

Oran Agra 59b4af8d 2009-04-05T18:23:38 Position Independent Code (PIC) support in autofit module. * include/freetype/internal/autohint.h add macros to init instances of FT_AutoHinter_ServiceRec. * src/autofit/afmodule.h declare autofit_module_class using macros from ftmodapi.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/autofit/afmodule.c when FT_CONFIG_OPTION_PIC is defined af_autofitter_service and autofit_module_class structs will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from afpic.h in order to access them. * src/autofit/aftypes.h add macros to init and declare instances of AF_ScriptClassRec. * src/autofit/afcjk.h declare af_cjk_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/afcjk.c when FT_CONFIG_OPTION_PIC is defined af_cjk_script_class struct will have function to init it instead of being allocated in the global scope. * src/autofit/afdummy.h declare af_dummy_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/afdummy.c when FT_CONFIG_OPTION_PIC is defined af_dummy_script_class struct will have function to init it instead of being allocated in the global scope. * src/autofit/afindic.h declare af_indic_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/afindic.c when FT_CONFIG_OPTION_PIC is defined af_indic_script_class struct will have function to init it instead of being allocated in the global scope. * src/autofit/aflatin.h declare af_latin_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/aflatin.c when FT_CONFIG_OPTION_PIC is defined af_latin_script_class struct will have function to init it instead of being allocated in the global scope. Change af_latin_blue_chars to be PIC-compatible by being a two dimentional array rather than array of pointers. * src/autofit/aflatin2.h declare af_latin2_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/aflatin2.c when FT_CONFIG_OPTION_PIC is defined af_latin2_script_class struct will have function to init it instead of being allocated in the global scope. Change af_latin2_blue_chars to be PIC-compatible by being a two dimentional array rather than array of pointers. * src/autofit/afglobal.c when FT_CONFIG_OPTION_PIC is defined af_script_classes array initialization was moved to afpic.c and is later refered using macros defeined in afpic.h. New Files: * src/autofit/afpic.h declare struct to hold PIC globals for autofit module and macros to access them. * src/autofit/afpic.c implement functions to allocate, destroy and initialize PIC globals for autofit module. * src/autofit/autofit.c add new file to build: afpic.c. * src/autofit/jamfile add new files to FT2_MULTI build: afpic.c.
