fa437d8d | 2017-01-31 23:06:38 | [cff] Provide metrics variation service interface (#50196). Only now I've got an OTF with an HVAR table for testing... The code in `ftmm.c' uses `FT_FACE_LOOKUP_SERVICE' to get the metrics variations interface. However, this didn't work with `FT_FACE_FIND_GLOBAL_SERVICE' used in `sfnt_init_face'. * src/cff/cffdrivr.c: Include FT_SERVICE_METRICS_VARIATIONS_H. (cff_hadvance_adjust, cff_metrics_adjust): Wrapper functions for metric service functions from the `truetype' module. (cff_service_metrics_variations): New service. (cff_services): Updated. * src/cff/cffpic.h (CFF_SERVICE_METRICS_VAR_GET): New macro. [FT_CONFIG_OPTION_PIC]: Synchronize code. * src/sfnt/sfobjs.c (sfnt_init_face): Replace call to FT_FACE_FIND_GLOBAL_SERVICE with `ft_module_get_service' to always load the service from the `truetype' module. | |

|
0918325e | 2016-12-14 20:44:11 | [sfnt, truetype] Add framework for Metrics Variations service. No effect yet; service functions will be implemented later on. Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. * include/freetype/internal/services/svmetric.h: New file. * include/freetype/internal/ftserv.h (FT_SERVICE_METRICS_VARIATIONS_H): New macro. * include/freetype/internal/tttypes.h (TT_Face): New field `var'. * src/sfnt/sfobjs.c: Include FT_SERVICE_METRICS_VARIATIONS_H.

(tt_services): Updated. * src/truetype/ttpic.h: Updated. | |
|
c628a7df | 2016-12-14 19:31:42 | [cff] Add Multiple Masters service. The code simply uses the MM functions from the `truetype' module. Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. * include/freetype/internal/tttypes.h (TT_Face): New field `mm'. * src/cff/cffdrivr.c: Include FT_SERVICE_MULTIPLE_MASTERS_H. (cff_set_mm_blend, cff_get_mm_blend, cff_get_mm_var, cff_set_var_design, cff_get_var_design): New functions. (cff_service_multi_masters): New service.

|
3205a44d | 2016-12-09 06:55:34 | [sfnt] Revert change from 2016-12-08. I missed the functionality of `ft_module_get_service', which makes the change unnecessary. | |
|
29aa9577 | 2016-12-08 08:59:34 | [sfnt] Add `get_glyph_name' and `get_name_index' to SFNT interface. CFF2 fonts will need access to those two functions. * include/freetype/internal/sfnt.h: Include FT_SERVICE_GLYPH_DICT_H. (SFNT_Interface): Add `get_glyph_name' and `get_name_index' members.

(sfnt_interface): Updated. | |
|
1c6fd994 | 2016-11-06 12:37:55 | [sfnt] Improve FT_LOAD_BITMAP_METRICS_ONLY for `sbix' format. It's unavoidable to call the PNG engine, but to get the metrics it is sufficient to read the PNG image's header only. * src/sfnt/pngshim.c (Load_SBit_Png): Add argument to control the allocation of the glyph slot. * src/sfnt/pngshim.h: Updated. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_png, tt_face_load_sbix_image, tt_face_load_sbit_image): Updated. | |
|
565db95b | 2016-11-06 12:33:51 | [sfnt] Speed up `sbix' lookup. This also fixes a bug introduced in 2016-10-01 which prevents display of embedded bitmap fonts that use the `sbix' format. * src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and offset also in `ebdt_size' and `ebdt_start', respectively. This makes the test for an embedded bitmap data table succeed for this format. (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use `ebdt_size' and `ebdt_start' (tt_face_load_sbix_image): Ditto. | |
|
37e193e9 | 2016-11-06 12:32:51 | Introduce a way of quickly retrieving (embedded) bitmap metrics. `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph until the user calls `FT_Render_Glyph'. However, it always allocates memory for bitmaps and copies or decodes the contents of a bitmap glyph, which can be quite slow for PNG data. * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New macro. * src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if FT_LOAD_BITMAP_METRICS_ONLY is used. * src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_bitmap): Add argument to control allocation of the glyph slot. (tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound, tt_face_load_sbit_image): Updated. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if `FT_LOAD_BITMAP_METRICS_ONLY' is set. * src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add argument to control allocation of the glyph slot. * src/pfr/pfrobjs (pfr_slot_load): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto. * docs/CHANGES: Updated. | |
|
57741403 | 2016-10-22 18:34:48 | [sfnt] Improve handling of invalid post 2.5 tables [#49393]. * src/sfnt/ttpost.c (load_format_25): We need at least a single table entry. | |
|
fcc0ee80 | 2016-10-01 20:12:25 | [sfnt] Disable bitmap strikes if we don't have a bitmap data table. * src/sfnt/ttsbit.c (tt_face_load_sbit): Check whether we have a bitmap data table. | |

2067c698 | 2016-09-29 19:49:07 | [truetype] Disallow bitmap strokes for non-default instances. Also speed up access of default instances if GX variations are active. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `is_default_instance' member. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `is_default_instance'. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Add test for default instance. (TT_Load_Glyph): Load embedded bitmaps for default instance only. * src/truetype/ttgxvar.c (TT_Set_MM_Blend): Compute `is_default_instance'. | |
|
bf90239c | 2016-09-29 13:04:46 | [truetype] Clean up `TT_Face' structure. * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused fields `horz_metrics' and `vert_metrics'. Update documentation. * src/sfnt/sfobjs.c (sfnt_done_face): Updated. | |

e421a0bf | 2016-09-10 08:02:30 | [sfnt] Fix previous commit. Problems reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40 We now map the strike index right before accessing the physical data, not earlier. * src/sfnt/sfobjs.c (sfnt_load_face): Set `face->sbit_strike_map' after creating the map so that... * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): ... this function can be used before and after setting up `sbit_strike_map'. (tt_face_set_sbit_strike): Revert change. (tt_sbit_decoder_init, tt_face_load_sbix_image): Map strike index. * src/truetype/ttdriver.c (tt_size_select): Revert change. | |
|
d609b7c1 | 2016-09-09 22:11:07 | [sfnt] Don't provide (completely) broken strike data. FreeType tries to sanitize strike header data; we now reject completely broken ones. * include/freetype/internal/tttypes.h (TT_FaceRec): New `sbit_strike_map' array pointer. * src/base/ftobjs.c (FT_Match_Size): Reject matches where either width or height would be zero. Add tracing message in case of error. * src/sfnt/sfobjs.c (sfnt_load_face): Populate `sbit_strike_map', only using (more or less) valid strike header data for FT_Face's `available_sizes' array. (sfnt_done_face): Updated. * src/sfnt/ttsbit.c (tt_face_set_sbit_strike): Use `sbit_strike_map'. (tt_face_load_strike_metrics): Improve tracing. * src/truetype/ttdriver.c (tt_size_select): Use `sbit_strike_map'. | |
|
d8ef7266 | 2016-09-02 23:27:50 | [sfnt] Avoid left shift of negative value (#48980). * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bit_aligned): Use unsigned constant. | |
|
f3e71bab | 2016-08-26 10:31:30 | [sfnt] Cache offset and size to bitmap data table. This commit avoids `EBDT' and friends being looked up again and again while loading a single embedded bitmap. * include/freetype/internal/tttypes.h (TT_FaceRec) [TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: New fields `ebdt_start' and `ebdt_size'. * src/sfnt/ttsbit.c (tt_sbit_decoder_init): Move table lookup to ... (tt_face_load_sbit): ... this function; also store the table size and offset. | |

|
53059f92 | 2016-08-07 09:01:33 | [sfnt] Fix `FT_Get_Advance' for bitmap strikes. `FT_Get_Advance' returns 0 for bitmap fonts. It first gets the advance value from the font table and then scales it by the `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't set that value for bitmap fonts and the advance gets scaled to zero. Taken from https://github.com/behdad/harfbuzz/issues/252 * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_EBLC>: Set scale values. | |

Since 2016-05-16 we detect infinite recursion directly. * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust `maxComponentDepth'. * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if `maxComponentDepth' is not valid. Instead, simply adjust its value and emit a tracing message. | |
|
ee3f36f6 | 2016-07-14 10:25:20 | [sfnt] Fix `face_index' value in `FT_Face' for named instances. * src/sfnt/sfobjc.s (sfnt_init_face): Don't strip off higher 16bits. | |

813aca51 | 2016-02-14 16:03:15 | [cff] Make old CFF engine show MM CFFs (without variations). The new code only displays the first master in the font. * src/cff/cffgload.c (cff_decode_parse_charstrings): Add new parameter to allow function calls from dictionaries also. <cff_op_blend>: Partially implement it. Update all callers. * src/cff/cffgload.h: Updated. * src/cff/cffparse.c (cff_parser_init): Add new parameter to pass the number of Multiple Master designs. Update all callers. (cff_parse_multiple_master): New function to rudimentarily parse operator. (cff_parser_run): Handle `T2' operator. * src/cff/cffparse.h: Updated. (CFF_ParserRec): Add `num_designs' field. * src/cff/cffload.c: Updated. * src/cff/cfftoken.h: Handle `MultipleMaster' operator. * src/cff/cfftypes.h (CFF_FontRecDictRec): Add `num_designs' field. * src/sfnt/sfobjs.c (sfnt_init_face): Don't handle `fvar' table for MM CFFs. | |

6f09011f | 2015-10-24 10:10:22 | [sfnt] Sanitize bitmap strike glyph height. Problem reported by Nikolay Sivov <bunglehead@gmail.com>. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Avoid zero value for `metrics->height' by applying some heuristics. | |
|
e93d326c | 2015-10-22 10:17:20 | [sfnt, type42] Fix clang compiler warnings. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `offset'. * src/type42/t42parse.c (t42_parse_sfnts): Use proper cast. | |

|
4f7f6f6e | 2015-10-11 07:55:25 | [sfnt] Improve extraction of number of named instances. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check number of instances against `fvar' table size. | |
|
8de39a79 | 2015-10-10 13:34:11 | [sfnt] Fix infinite loops with broken cmaps (#46167). * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next): Take care of border condidions (i.e., if the loops exit naturally). | |
|
983b00ec | 2015-10-08 18:44:45 | [sfnt] Fix some signed overflows (#46149). * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use `FT_MulDiv'. | |

5339c75e | 2015-09-24 13:39:44 | [sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs. | |

730b6d74 | 2015-09-19 12:41:12 | [sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly. | |
