1dee4bf9 | 2017-02-05 08:33:10 | [autofit] Use better blue zone characters for lowercase latin. The number of lowercase characters for computing the top flat blue zone value was too small (in most cases only `x' and `z'). If one of the two characters has a large serif, say, it can happen that FreeType must select between two different values, having a 50% chance to use the wrong one. As a result, rendering at larger PPEM values could yield uneven lowercase glyph heights. Problem reported by Christoph Koeberlin <christoph@koe.berlin>. * src/autofit/afblue.dat (AF_BLUE_STRING_LATIN_SMALL): Replaced with... (AF_BLUE_STRING_LATIN_SMALL_TOP, AF_BLUE_STRING_LATIN_SMALL_BOTTOM): ... New, extended sets. (AF_BLUE_STRINGSET_LATN): Updated. * src/autofit/afblue.c, scr/autofit/afblue.h: Regenerated. | |

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...

08fd250e | 2017-01-09 11:30:32 | [pcf] Make long family names configurable. The change from 2016-09-29 was too radical (except for people using the openSuSE GNU/Linux distribution).

a300c1c3 | 2016-12-24 09:27:15 | * src/truetype/ttpload.c (tt_face_load_hdmx): Ignore `version'. Problem reported by 張俊芝 <418092625@qq.com>. | |
|
d1db57c2 | 2016-12-24 09:05:16 | * src/sfnt/ttsbit.c (tt_face_load_sbit): Allow more version values. Some fonts seem to have the `version' field in the wrong byte order. Problem reported by 張俊芝 <418092625@qq.com>. | |
|
fde0b78c | 2016-12-24 08:17:19 | * src/truetype/ttpload.c (tt_face_load_loca): Sanitize table length. This trivial fix allows us to accept more fonts. Problem reported by 張俊芝 <418092625@qq.com>. | |

|
72091103 | 2016-12-21 23:46:29 | * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. I should really stop coding late in the evening... Thanks again to Ben for checking. | |
|
d44daf9e | 2016-12-21 23:03:48 | * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. Don't apply deltas twice for non-phantom points. Spotted by Ben Wagner. | |
|
e6a429e2 | 2016-12-21 20:27:48 | [cff, truetype] Another try for #49829. * src/cff/cffdrivr.c: Don't include `FT_SERVICE_METRICS_VARIATIONS_H'. (cff_get_advances): Use `ttface->variation_support'. * src/truetype/ttdriver.c (tt_get_advances): Use `ttface->variation_support'. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Use `ttface->variation_support'. | |
|
64a91137 | 2016-12-21 19:30:33 | [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. | |
|
57a6733d | 2016-12-21 06:52:23 | [base] Improve sanity check for Mac resources (#49888). * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Abort if `rlen' is not positive. | |
|
ded4bdb5 | 2016-12-20 23:26:38 | [base] More sanity checks for Mac resources. We use https://github.com/kreativekorp/ksfl/wiki/Macintosh-Resource-File-Format and https://developer.apple.com/legacy/library/documentation/mac/pdf/MoreMacintoshToolbox.pdf#page=151 as references. * include/freetype/internal/ftrfork.h (FT_RFork_Ref): Use FT_Short for `res_id'. * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Extract map length and use it to improve sanity checks. Follow the specification more closely;in particular, all data types are signed, not unsigned. (FT_Raccess_Get_DataOffsets): Follow the specification more closely; in particular, all data types are signed, not unsigned. Add some sanity checks. | |

70704b34 | 2016-12-20 12:27:22 | [truetype] Improve logic for getting fast advance widths. * src/cff/cffdrivr.c (cff_get_advances), src/truetype/ttdriver.c (tt_get_advances): Use `is_default_instance' for test; this gets recomputed after changing blend coordinates. | |
 |
cc576f80 | 2016-12-20 11:37:42 | [truetype] Fix linear metrics of GX variation fonts. When asking for an unhinted non-default variations, `linearVertAdvance' is currently the value from the `hmtx' table instead of the actual value after applying the variation. `HVAR' support fixes this, but fonts will exist without that table and will need sane fallback. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Implement linear advance adjustments if `HVAR' or `VVAR' tables are missing. | |
|
a1e85f11 | 2016-12-20 10:52:26 | [cff, truetype] Fast advance width retrieval for fonts with HVAR. Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Don't handle MM. * src/cff/cffdrivr.c: Include FT_SERVICE_METRICS_VARIATIONS_H. (cff_get_advances): Test for HVAR and VVAR. * src/truetype/ttdriver.c (tt_get_advances): Test for HVAR and VVAR. | |

(ft_open_face_internal): ... this function. Add a parameter to control whether we try special Mac font handling in case of failure. (FT_Open_Face, FT_New_Face, FT_New_Memory_Face, open_face_from_buffer): Use `ft_open_face_internal'. | |
|
ca3d4019 | 2016-12-18 18:23:19 | * src/cff/cffobjs.c (cff_face_init): Make named instances work. | |
|
a8652c59 | 2016-12-18 18:12:03 | [truetype, cff] Extend `get_var_blend' function of MM service. In particular, we need access to named instance data. * include/freetype/internal/services/svmm.h (FT_Get_Var_Blend_Func): Add argument for `FT_MM_Var'. * src/cff/cffload.c (cff_get_var_blend): Updated. * src/cff/cffload.h: Updated. * src/cff/cf2ft.c (cf2_getNormalizedVector): Updated. * src/truetype/ttgxvar.c (tt_get_var_blend): Updated.

|
25f3ac2b | 2016-12-18 15:50:18 | [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. | |
|
eb6d0208 | 2016-12-18 09:29:58 | Minor GX code shuffling. * include/freetype/internal/tttypes.h (TT_Face): Move `is_default_instance' into TT_CONFIG_OPTION_GX_VAR_SUPPORT block. * src/sfnt/sfobjs.c (sfnt_init_face): Updated. * src/truetype/ttgload.c (IS_DEFAULT_INSTANCE): New macro. (TT_Load_Glyph): Use it. | |
|
8f633a08 | 2016-12-18 06:42:31 | [cff] Better handling of non-CFF font formats. * src/cff/cffload.c (cff_font_load): Pure CFFs don't have a signature, so return `FT_Err_Unknown_File_Format' more often. | |
|
4cd68179 | 2016-12-17 22:52:50 | * src/cff/cffload.c (cff_build_blend_vector): Remove redundant code. | |
