Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=759 * src/sfnt/sfobjs.c (sfnt_init_face): While setting number of instances to zero for `CFF' fonts table, ensure that there is no `CFF2' present also (which gets priority).
77930974	2017-03-07T17:27:58	[sfnt] Improve handling for buggy variation fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=738 * src/sfnt/sfobjs.c (sfnt_init_face): While setting number of instances to zero for `CFF' fonts table, ensure that there is no `glyf' present also (which gets priority).
27fee7f8	2017-03-06T20:45:44	[sfnt, truetype] Always provide default instance. As documented in the OpenType specification, an entry for the default instance may be omitted in the named instance table. In particular this means that even if there is no named instance table in the font we actually do have a named instance, namely the default instance. For consistency, we always want the default instance in our list of named instances. If it is missing, we try to synthesize it. * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default instance is in the table of named instances. Otherwise adjust number of instances. * src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H. (TT_Get_MM_Var): Use `face->root.style_flags' as the number of named instances. Sythesize a named instance entry if necessary. (tt_done_blend): Free `normalized_stylecoords'.

Update callers. (search_name_id): Fix return value.
b653a230	2017-02-26T11:23:07	[sfnt] Split off another bit of `sfnt_get_ps_name'. * src/sfnt/sfdriver.c (sfnt_get_ps_name): Split off some functionality into... (search_name_id): ... New function.
c1abd6aa	2017-02-23T22:58:14	[sfnt] Modularize `sfnt_get_ps_name'. * src/sfnt/sfdriver.c (sfnt_get_ps_name): Split off some functionality into... (IS_WIN, IS_APPLE): ... New macros. (get_win_string, get_apple_string): ... New functions.
fa437d8d	2017-01-31T23:06:38	[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.

63765a8f	2017-01-01T10:43:41	[sfnt] Return correct number of named instances for TTCs. Without this patch, requesting information for face index N returned the data for face index N+1 (or index 0). * src/sfnt/sfobjs.c (sfnt_init_face): Correctly adjust `face_index' for negative `face_instance_index' values.
f80c4473	2016-12-26T23:57:45	Replace `++foo' and `--foo' with `foo++' and `foo--', resp.
4441f7b2	2016-12-26T17:08:17	Replace `foo == NULL' and `foo != NULL' with `!foo' and `foo', resp. Other minor formatting.

64a91137	2016-12-21T19:30:33	[truetype, sfnt] Introduce font variation flags to `TT_Face'. * include/freetype/internal/tttypes.h (TT_FACE_FLAG_VAR_XXX): New macros describing available functionality of various OpenType tables related to font variation. (TT_Face): New fields `variation_support' and `mvar_support', replacing and extending `use_fvar'. * src/sfnt/sfobjs.c (sfnt_init_face, sfnt_load_face): Use `variation_support'. * src/truetype/ttgxvar.c (ft_var_load_hvar): Set `variation_support' field. (TT_Vary_Apply_Glyph_Deltas): Updated.
25f3ac2b	2016-12-18T15:50:18	[sfnt] Handle `fvar' with zero axes as a non-MM font. This is better behaviour than exiting with an error. * include/freetype/internal/tttypes.h (TT_Face): Add `use_fvar' field. * src/sfnt/sfobjs.c (sfnt_init_face): Compute `use_fvar', also updating the validation code. Use `use_fvar' to compute FT_FACE_FLAG_MULTIPLE_MASTERS. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Remove `fvar' validation code.

(tt_face_get_metrics): Apply metrics variations.
0918325e	2016-12-14T20:44:11	[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. (sfnt_init_face): Initialize `face->var'. * src/truetype/ttdriver.c: Include FT_SERVICE_METRICS_VARIATIONS_H. (tt_service_metrics_variations): New service. (tt_services): Updated. * src/truetype/ttpic.h: Updated.
c628a7df	2016-12-14T19:31:42	[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	2016-12-09T06:55:34	[sfnt] Revert change from 2016-12-08. I missed the functionality of `ft_module_get_service', which makes the change unnecessary.
29aa9577	2016-12-08T08:59:34	[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. (FT_DEFINE_SFNT_INTERFACE): Updated. * src/sfnt/sfdriver.c (sfnt_get_glyph_name, sfnt_get_name_index): Fix signatures to exactly correspond to the glyph dict service function typedefs. (sfnt_interface): Updated.
1c6fd994	2016-11-06T12:37:55	[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	2016-11-06T12:33:51	[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	2016-11-06T12:32:51	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.

730b6d74	2015-09-19T12:41:12	[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.

In particular this means that even if there is no named instance table in the font we actually do have a named instance, namely the default instance. For consistency, we always want the default instance in our list of named instances. If it is missing, we try to synthesize it. * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default instance is in the table of named instances. Otherwise adjust number of instances. * src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H. (TT_Get_MM_Var): Use `face->root.style_flags' as the number of named instances. Sythesize a named instance entry if necessary. (tt_done_blend): Free `normalized_stylecoords'.

[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.

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'.

[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.

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.

[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.

[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.
