| |
| Fix invalid function pointer casts. |
| |
| This change should allow Freetype to work on WASM/Emscripten without |
| needing `-s EMULATE_FUNCTION_POINTER_CASTS=1'. |
| |
| * src/autofit/afdummy.c (af_dummy_hints_apply): Fix signature. |
| |
| * src/cid/cidload.c (cid_parse_font_matrix, parse_fd_array, |
| parse_expansion_factor, parse_font_name): Return `void', not |
| `FT_Error'. |

| [base] Handle numeric overflow (#55827). |
| |
| * src/base/ftglyph.c (FT_Glyph_Get_CBox): Use `FT_PIX_CEIL_LONG'. |
| |
| 2019-03-05 Sebastian Rasmussen <sebras@gmail.com> |
| |
| [psaux] Fix use of uninitialized memory (#55832). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString): The call to |
| `cf2_arrstack_setCount' may fail because the allocator ran out of |
| memory. When this happens the stack is still written to before the |
| error condition is checked. This means that FreeType writes outside |
| of allocated memory. This commit moves the error check prior to the |
| stack assignment, hence the function now properly returns with an |
| error condition. |
| |
| 2019-02-23 Werner Lemberg <wl@gnu.org> |
| |
| * src/base/ftbitmap.c (FT_Bitmap_Blend): No fractional offsets. |
| |
| The function only provided a framework without an actual |
| implementation, which this commit removes. |
| |
| 2019-02-23 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/update-copyright-year: Insert `(C)'. |
| |

| |
| 2019-02-02 Nikolaus Waxweiler <madigens@gmail.com> |
| |
| [truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics. |
| |
| Instead of setting typo or win metrics as the new `FT_Face' metrics |
| indiscriminately, apply only typo deltas to the currently active |
| `FT_Face' metrics. This prevents line height differences when the |
| default outlines were used as the regular face and instances for |
| everything else, for example. |
| |
| * src/truetype/ttgxvar.c (tt_apply_mvar): Implement. |
| |
| 2019-02-02 Nikolaus Waxweiler <madigens@gmail.com> |
| |
| [sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set. |
| |
| If the `OS/2' table exists and `fsSelection' bit 7 |
| (USE_TYPO_METRICS) is set, use the `sTypo*' set of values to compute |
| the `FT_Face's ascender, descender, and height. Otherwise, fall |
| back to old behavior. |
| |
| * src/sfnt/sfobjs.c (sfnt_load_face): Implement. |
| |

| [sfnt] Handle TT fonts having two PostScript font names (#55471). |
| |
| * src/sfnt/sfdriver.c (sfnt_get_name_id): Prefer English over any |
| other language found for PostScript font names. |
| |
| 2019-01-08 Chris Liddell <chris.liddell@artifex.com> |
| |
| [psaux] Fix closepath (#55414). |
| |
| All of the Type 1 path building is done with code common to the |
| revised CFF engine, with the exception of closepath, which was still |
| calling ps_builder_close_contour(), thus previously cached segments |
| were not always written to the path, and glyph corruption, or even |
| invalid outlines were possible. |
| |
| * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: |
| Switch to calling `cf2_glyphpath_closeOpenPath'. |
| |
| 2018-12-29 Werner Lemberg <wl@gnu.org> |
| |

| [gxvalid] Fix compiler warnings. |
| |
| * src/gxvalid/gxvjust.c (gxv_just_check_max_gid), |
| src/gxvalid/gxvmort.c (gxv_mort_coverage_validate): Use `FT_UNUSED'. |
| |
| 2018-12-11 Werner Lemberg <wl@gnu.org> |
| |
| * src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test. |
| |
| `control_len' only gets its value from `n_ins' (and vice versa), |
| which is always read as `unsigned short' and thus can't be larger |
| than 0xFFFF. |
| |
| 2018-12-04 Werner Lemberg <wl@gnu.org> |

| [type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls. |
| |

| the WeightVector of an existing font instance, this addition |
| supports that use. |
| |
| * include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector, |

| Fix handling 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. |

| * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Another tweak. |
| |
| This one should be clearer. When the rounded monochrome bbox collapses |
| we add a pixel that covers most if not all original cbox. |
| |

| |
| Improve auto-hinter handling of bitmap fonts (#54681). |
| |
| For bitmap fonts, `FT_Load_Glyph' should either return an error or |
| not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this |
| case `FT_Load_Glyph' calls into the auto-hinter which calls back |
| into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which |
| marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path |
| (even though it doesn't have any path). It appears that the |
| auto-hinter should not be called when the face doesn't have |
| outlines. The current test for using the auto-hinter in |
| `FT_Load_Glyph' checks whether the driver supports scalable |
| outlines, but not if the face supports scalable outlines. |
| |
| * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have |
| scalable outlines. |

| [raster] Fix disappearing vertical lines (#54589). |

| |
| 2018-09-20 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Tiny rounding tweak. |
| |
| This adds pixels in case a contour goes through the center |
| and they need to be turned on in the b/w rasterizer. |
| |
| 2018-09-20 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [pcf] Replace charmap implementation. |
| |
| PCF comes with charmap lookup table, aka PCF encodings. Using it |
| directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times |
| faster than the original BDF-like binary searches. |
| |

| [base] Fix mono bitmap presetting (#53896). |
| |
| It is rather fundamental to set monochrome bitmap based on rounded |
| CBox because the b/w rasterizer turns on pixels when their centers are |
| inside the glyph outline. The dropout control is unpredictable and can |
| distort narrow glyphs if the bitmap is too wide. |
| |
| Reported by Chris Liddell. |
| |
| * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): If BBox boundaries |

| |
| [sfnt] Preliminary support of coloured layer outlines (#44689). |
| |
| This commit enables OpenType's COLR/CPAL table handling; a typical |
| application are color emojis that can be scaled to any size. |
| |
| If the color palette does not exist or is invalid, the rendering |
| step rasterizes the outline instead. The current implementation |
| assumes that the foreground is black. |
| |
| Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS. |
| |
| There are still some issues with metrics; additionally, an API to |
| fetch color layers is missing. |
| |
| * devel/ftoption.h, include/freetype/config/ftoption.h |
| (TT_CONFIG_OPTION_COLOR_LAYERS): New macro. |
| |
| * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec, |

| and `colr_blend' fields. |

| |
| Fix DLL compilation on Solaris. |
| |
| AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The |
| Solaris Studio 12.1 through 12.5 compilers see the |
| `-fvisibility=hidden' flag, but ignore it with a warning of: |
| |
| cc: Warning: Option -fvisibility=hidden passed to ld, |
| if ld is invoked, ignored otherwise |
| |
| AC_LINK_IFELSE does the compile and then tries to link the result, |
| at which point the Solaris linker will issue an error: |
| |
| ld: fatal: option '-fvisibility=hidden' is incompatible with |
| building a dynamic executable |
| |
| If we don't use AC_LINK_IFELSE to catch the error, then configure |
| will fail further tests which attempt to link, such as those testing |
| dependencies like `libbz2'. |
| |
| Also, don't try adding `-fvisibility' if we have already added |
| `-xldscope', just use one of them, since Sun Studio 12 and earlier |
| compilers only issue a warning, and don't try passing through to the |
| linker to generate an error, so AC_LINK_IFELSE doesn't catch them. |
| |
| Tested on Solaris 11.4 beta with compiler versions: |
| |
| Sun Studio 8 (Sun C 5.5) |
| Sun Studio 10 (Sun C 5.7) |
| Sun Studio 11 (Sun C 5.8) |
| Sun Studio 12 (Sun C 5.9) |
| Sun Studio 12.1 (Sun C 5.10) |
| Oracle Solaris Studio 12.2 (Sun C 5.11) |
| Oracle Solaris Studio 12.3 (Sun C 5.12) |
| Oracle Solaris Studio 12.4 (Sun C 5.13) |
| Oracle Developer Studio 12.5 (Sun C 5.14) |
| Oracle Developer Studio 12.6 (Sun C 5.15) |
| gcc 5.5.0 |
| gcc 7.3.0 |
| |
| and verified the libfreetype.so.6 generated by each of those |
| compilers exported the same set of symbols. |

| * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive |

| |
| This brings up the minimum required CMake version to 2.8.12. |
| |
| The installation paths follow the GNU defaults now, e.g. installing on a |
| 64 bit host will place binaries into the lib64/ folder on e.g. Fedora. |
| |
| Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC). |
| |
| CMake will no longer look for a C++ compiler. |
| |
| Library and .so version now match the Autotools build. |
| |
| Comments in the build file and informational messages now use platform |
| agnostic example commands. |
| |
| ftoption.h and ftconfig.h are written directly without a redundant `-new' |
| copy. |
| |
| External dependencies are expressed as option()s and will turn up as such |
| in cmake-gui. |
| |
| Internal: Properties such as dependencies and include directories are now |
| privately set on the freetype library instead of globally. |
| |
| The CPack definitions have been cleaned up, the `make dist' has been |
| removed. Source packages generated with CPack don't contain Autotools |
| files and aren't used by the maintainers anyway. |
| |
| On Windows, src/base/ftver.rc is compiled to decorate the library with |
| version and copyright information. |
| |
| A pkg-config file is now generated and installed. |

| [psaux] Fix Type 1 glyphs with too many stem hints. |
| |
| According to the CFF specification, charstrings can have up to 96 stem |
| hints. Due to hint replacement routines in Type 1 charstrings, some |
| glyphs are rejected by the Adobe engine, which implements the above |
| limit. This fix turns off hinting for such glyphs. |

| [sfnt] Fix charmap type 2 iterator (#52646). |
| |
| The subsetted demo font of the report that exhibits the bug has a |
| very unusual type 2 cmap for Unicode(!): It contains only two |
| sub-headers, one for one-byte characters (covering the range 0x20 to |
| 0xFA), and a second one for higher byte 0x01 (just for character |

| [psaux] Fix CFF advance widths. (#52466) |
| |
| Glyph advance widths were being written to the new `PS_Decoder' but not |

| |
| Use Adobe hinting engine for `light' hinting of both CFF and Type 1. |
| |
| Since Ewald Hew factored the Adobe hinting engine out of the CFF |
| driver code, we can now use it on Type 1 (and CID) font formats, as |
| both have the same hinting philosophy. |
| |
| This change activates the Adobe hinter when in LIGHT mode, and |
| therefore always unless explicitly asking for the auto-hinter. This |
| makes LIGHT behavior consistent with CFF fonts. As of this commit, |
| the hinting engine table looks as follows. |

| |
| The interpreter in Type 1 mode rewinds the charstring after collecting |
| all hints for building the initial hintmap (commit d52dd7f). However, |
| some charstrings use `endchar' in a final subroutine call, rewinding to |
| the start of that subroutine, and only a small section of the actual |
| glyph is drawn. |

| * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: |

| [smooth] Fix complex rendering at high ppem. |

| rendering memory pool. Now we bisect the bands vertically so that |

| |
| Bitmap metrics presetting [1/2]. |
| |
| This mainly just extracts the code for presetting the bitmap metrics |
| from the monochrome, grayscale, and LCD renderers into a separate |
| function. |
| |
| * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): New function that |
| calculates prospective bitmap metrics for the given rendering mode. |
| * include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap): |
| Declare it. |
| |
| * src/base/ftlcdfil.c (ft_lcd_padding): New helper function that adds |
| padding to CBox taking into account pecularities of LCD rendering. |
| * include/freetype/ftlcdfil.h (ft_lcd_padding): Declare it. |
| |
| * src/raster/ftrend1.c (ft_raster1_render): Reworked to use |
| `ft_glyphslot_preset_bitmap'. |
| * src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto. |
| (ft_smooth_render_lcd, ft_smooth_render_lcd): The pixel_mode setting |
| is moved to `ft_glyphslot_preset_bitmap'. |

| test. |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) |
| <cf2_escCALLOTHERSUBR>: Add casts. |
| |
| * src/psaux/psobjs.c (ps_decoder_init): Add cast. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Minor fixes. |
| |

| Rearrange `ps_builder_init' arguments to conventional order. |
| |
| * src/psaux/psft.c (cf2_decoder_parse_charstrings): Add a check and |
| notice for `SubFont' in Type 1 mode. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Move `psdecode' into `psobjs'. |
| |
| As the former only contains a single procedure, move it into |
| `psobjs' for simplicity. Also change the parameter order to the |
| conventional one. |
| |
| * src/psaux/psdecode.c (ps_decoder_init): Moved to... |
| * src/psaux/psobjs.c: ...Here. |
| * src/psaux/psdecode.h, src/psaux/psobjs.h: Ditto. |
| |
| * include/freetype/internal/psaux.h (PSAux_ServiceRec): Update |
| `ps_decoder_init' function signature. |

| Update file references. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Fix Type 1 hinting. |
| |
| Type 1 hinting breaks sometimes when mid-charstring hints should |
| have been in the initial hintmap. This fix adds a preprocessing |
| pass that reads all hints and builds the correct initial hintmap |
| first, before proceeding to build the glyph outline. |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString): New |
| `initial_map_ready' boolean flag. |
| Ignore outline commands and hint changes on first pass. |
| <cf2_cmdENDCHAR>: Add section to build hintmap and rewind. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Add tracing for hints. |
| |
| * src/psaux/pshints.c (cf2_hintmap_dump): New function. |
| (cf2_hintmap_insertHint): Trace incoming and inserted hints. |
| (cf2_hintmap_build): Dump hintmap before and after hint adjustment. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Minor fixes. |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString): Fix check for pop |
| results. |
| s/font->decoder/decoder/ where necessary. |
| <cf2_cmdHSTEM, cf2_cmdVSTEM, cf2_escHSTEM3, cf2_escVSTEM3>: Use |
| offset parameter in `cf2_doStems' instead of doing correction for |
| left-sidebearing. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [cid] Use the new engine. |
| |
| * src/cid/cidgload.c: Update includes. |
| (cid_load_glyph, cid_slot_load_glyph): Implement changes to glyph |
| loading code as with `type1' module. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [cid] Add Adobe engine configuration. |
| |
| This is similar to what was done in the `type1' module. |
| |
| * src/cid/cidriver.c (t1cid_driver_class): Update declaration. |
| * src/cid/cidobjs.c: Include FT_TYPE1_DRIVER_H. |
| (cid_driver_init): Update code. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Change subfont synthesis for CID fonts. |
| |
| Change `t1_make_subfont' to take in the Private dict record as an |
| argument. This is because Type 1 and CID font records in FreeType |
| have this in different places. |
| |
| * src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to |
| `FT_Face' so that CID is also accepted. |
| Take `PS_Private' as an argument and let caller figure out where the |
| Private dict actually is. |
| Update references. |
| |
| * include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update |
| declaration. |
| |
| * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update |
| call. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [type1] Switch to Adobe engine. |
| |
| * src/type1/t1objs.c (T1_Driver_Init): Set default to Adobe engine. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (seac). |
| |
| This concludes the changes needed to add Type 1 support. |
| |
| * src/psaux/psintrp.c: Update includes. |
| (cf2_interpT2CharString) <cf2_escSEAC>: Implement this similarly to |
| implied seac for CFF. |
| |
| * src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode_ps): New |
| function to look up the glyph index. |
| |
| * src/psaux/psft.c (cf2_getT1SeacComponent, |
| cf2_freeT1SeacComponent): New functions to get the charstrings for |
| seac components. |
| |
| * src/psaux/t1decode.h, src/psaux/psft.h: Update declarations. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (flex in callothersubr). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) |
| <cf2_escCALLOTHERSUBR>: Fix Flex feature handling (OtherSubrs 0, 1, |
| 2). |
| <cf2_cmdRMOVETO>: Do not actually move the `glyphPath' while doing |
| flex. This is to avoid closing the current contour. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (callothersubr). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) |
| <cf2_escCALLOTHERSUBR>: Copy code from |
| `t1_decoder_parse_charstrings' (in `t1decode.c'). |
| OtherSubr 3 (change hints) should reset the hintmask, so that the |
| new hints are applied. |
| Fix function calls and stack access. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (pop). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString): Change how unhandled |
| OtherSubr results are stored. Implement the PostScript stack using |
| an array. |
| <cf2_escPOP>: Ensure that the stack is not cleared after getting |
| `OtherSubr' results. |
| Fix stack access. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (callsubr). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>: |
| Type 1 mode. |
| |
| * src/psaux/psft.c (cf2_initLocalRegionBuffer): Add Type 1 mode. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (div, four-byte numbers). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add |
| Type 1 mode. Type 1 requires large integers to be followed by |
| `div'; cf. `Adobe Type 1 Font Format', section 6.2. |
| <op == 255>: Push Type 1 four-byte numbers as `Int' always. This is |
| to ensure `div' and `callsubr' get values they can use. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (hints). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, |
| cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode. |
| Allow adding hints mid-charstring. |
| <cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands |
| for three normal stem hints. This requires some recalculation of |
| stem positions. |
| Correction for left sidebearing. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (hsbw, sbw). |
| |
| * src/psaux/psintrp.c (cf2_doStems): `hsbw' or `sbw' must be the |
| first operation in a Type 1 charstring. |
| (cf2_interpT2CharString): Remove unused variables. |
| <cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw' |
| must be the first operation in a Type 1 charstring. |
| <cf2_cmdHSBW, cf2_escSBW>: Fix data access and add correction for |
| left sidebearing. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (setcurrentpoint). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) |
| <cf2_escSETCURRENTPT>: Fix stack access. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Extend Adobe interpreter (closepath). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>: |
| Use the right builder function. We can use the `haveWidth' boolean |
| already present, instead of implementing `parse_state'. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Add Type 1 operations to Adobe CFF interpreter. |
| |
| The following Type 1 specific ops have been added (copied from |
| `t1decode'): |
| |
| closepath |
| vstem3 |
| hstem3 |
| seac |
| sbw |
| callothersubr |
| pop |
| setcurrentpoint |
| hsbw |
| |
| The following require a Type 1 mode, because of differences in |
| specification: |
| |
| hstem |
| vstem |
| vmoveto |
| callsubr |
| div |
| rmoveto |
| hmoveto |
| Numbers |
| |
| The subsequent commits will implement these changes and adapt |
| accesses of data and objects to the new interpreter. |
| |
| NOTE: Will not compile in the meantime! |
| |
| * src/psaux/psintrp.c: Add opcodes to enum. |
| (cf2_interpT2CharString): Copy relevant code over from |
| `t1_decoder_parse_charstrings' (in `t1decode.c'). |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [type1] Fixes for rendering. |
| |
| The Type 1 advance width calculation passes null for glyph slot, |
| etc, which can cause null pointer access in the new interpreter. |
| Fall back to the old one for now. |
| |
| Fix the large glyph retry code and ensure hinting and scaling flags |
| are set properly. |
| |
| * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a |
| check for metrics_only. |
| Set the `force_scaling' flag. |
| (T1_Parse_Glyph): Updated. |
| (T1_Load_Glyph): Add `hinting' and `scaled' flags. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Add missing objects (2/2). |
| |
| Synthesize a `SubFont' object for Type 1 fonts. This is used in the |
| interpreter to access Private dict data, which are stored in |
| different places for Type 1 and CFF. This allows the same data to |
| be used in either mode. |
| |
| * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy |
| required values to a dummy `CFF_SubFont' object. This is similar to |
| `cff_make_private_dict'. |
| * src/psaux/psobjs.h: Add the new declaration. |
| |
| * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. |

| * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. |
| (T1_Parse_Glyph_And_Get_Char_String): Add the call. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Add missing objects for Type 1 (1/2). |
| |
| Move `CF2_Font' instance to `PS_Decoder'. This is the context for |
| the interpreter and since it is currently stored in `CFF_Font', is |
| unavailable in Type 1 mode. |
| |
| * include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New |
| `cf2_instance' field. |
| |
| * src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to |
| `PS_Decoder'. |
| |
| * src/psaux/t1decode.c (t1_decoder_done): Add finalization code. |
| |
| * src/psaux/psft.c (cf2_decoder_parse_charstrings): Update accesses. |

| function declarations. |
| * src/psaux/psauxmod.c (T1_Decoder_FuncsRec): Register the |
| callbacks. |
| |
| * src/psaux/psobjs.c (ps_builder_add_point): Add conditionals for |
| number conversion. |
| |
| * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add code |
| to choose which renderer to use. |
| |
| * src/cid/cidgload.c (cid_load_glyph): Update call. |
| * src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update |
| includes. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [type1] Add Adobe engine configuration. |
| |
| Use the previously changed PS_Driver in type1 module to store |
| hinting engine configuration. |
| |
| * include/freetype/ftt1drv.h: New file. |
| Duplicate and rename config options from CFF. |
| * include/freetype/config/ftheader.h (FT_TYPE1_DRIVER_H): New macro. |
| |
| * src/type1/t1driver.c (t1_driver_class): Update declaration. |
| * src/type1/t1objs.c: Include FT_TYPE1_DRIVER_H. |
| (T1_Driver_Init): Update code. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [cff] Move and rename `CFF_Driver'. |
| |
| This is so that we can use the same hinting engine parameters for |
| Type 1. |
| |
| * include/freetype/internal/cffotypes.h (CFF_Driver): Rename and |
| move to... |
| * include/freetype/internal/psaux.h (PS_Driver): ...here. |
| |
| * src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffload.c, |
| src/cff/cffobjs.c, src/cff/cffobjs.h, src/psaux/psft.c, |
| src/psaux/psobjs.c: Update references. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux, type1] Reorganize object fields. |
| |
| Make some fields more generic, so that we can access them the same |
| way regardless of Type 1 or CFF. |
| |
| * include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face' |
| to `FT_Face'. |
| Remove unused fields. |
| |
| * src/psaux/psft.c: Update all accesses of `PS_Builder.face'. |
| Add some asserts to guard against casting `T1_Face' as `TT_Face'. |
| |
| * src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow |
| `CFF_GlyphSlot', so that we can pretend they are the same in the |
| interpreter. |
| |
| * src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point): |
| Updated with above changes. |
| |
| 2017-09-25 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Prepare for Type 1 mode. |
| |
| Add some checks for Type 1 data passing through. |
| |
| * src/psaux/psfont.h (CF2_Font): Add `isT1' flag. |

| to use new objects. |
| |
| 2017-09-24 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Objects for new interpreter (part 2). |
| |
| Make the new objects copy over values. They are essentially wrapper |
| types for the different decoders/builders. |
| |
| * include/freetype/internal/psaux.h: Update declarations. |
| (PS_Builder): Add `is_t1' flag. |
| (PS_Decoder_{Get,Free}_Glyph_Callback): Renamed to... |

| service. |
| |
| 2017-09-24 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Add objects for new interpreter. |
| |
| Introduce `PS_Decoder' and `PS_Builder' which include all fields |
| from either Type 1 or CFF decoders/builders. |
| |
| * include/freetype/internal/psaux.h (PS_Builder, PS_Decoder): New |
| structs. |
| |
| * src/psaux/psobjs.c, src/psaux/psobjs.h: Add `PS_Builder' |
| functions. |
| |
| * src/psaux/psdecode.c, src/psaux/psdecode.h: New files to hold |

| src/psaux/rules.mk (PSAUX_DRV_SRC): Updated. |
| |
| 2017-09-24 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Rename files. |
| |
| Replace the `cf2' file name prefix with `ps' as the Adobe engine |
| will be used for both PostScript Types 1 and 2 (CFF) instead of just |
| CFF. |
| |
| s/cf2/ps/ for all following. |
| |
| * src/psaux/cf2*: Rename files. |
| * src/psaux/*: Update includes. |
| |
| * src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRC_SRC, |
| PSAUX_DRV_H): Update file references. |
| |
| 2017-09-24 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux] Minor fix. |
| |
| Use `MultiMasters' service in `psaux' instead of a call to `cff'. |
| The project builds if CFF_CONFIG_OPTION_OLD_ENGINE is not defined. |
| |
| * src/psaux/cf2ft.c: Update includes. |
| (cf2_getNormalizedVector): Use `mm->get_var_blend' instead of |
| `cff_get_var_blend'. |
| |
| 2017-09-24 Ewald Hew <ewaldhew@gmail.com> |
| |
| [psaux, cff] Move `cff_random' into `psaux' service. |
| |
| NOTE: Does not compile! |
| |
| Minor fix to allow both `cff' and `psaux' to use `cff_random'. |

| 2017-09-24 Ewald Hew <ewaldhew@gmail.com> |
| |
| [cff] Move struct declarations to `freetype/internal'. |
| |
| NOTE: Does not compile! |
| |
| This is so that the CFF functions moved to `psaux' can access the |
| same structs that they need. |
| |
| * src/cff/cfftypes.h: Moved to... |
| * include/freetype/internal/cfftypes.h: ...Here. |

| |
| [cff] Fix family name logic of pure CFF fontdata (#52056). |
| |
| 1. If `FamilyName' is present in the CFF font, use this for |
| FT_Face's `family_name'. |
| 2. Otherwise, use the face name and chop off any subset prefix. |
| 3. If at this point FT_Face's `family_name' is set, use this |
| together with the full name to determine the style. |
| 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. |
| 5. If we don't have a valid style, use "Regular". |
| |
| Previously, FT_Face's `family_name' entry for pure CFF fontdata |
| nearly always was the fontname itself, instead of the `FamilyName' |
| entry in the CFF font (assuming there is one). |
| |
| * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it. |
| |
| 2017-09-18 Alexei Podtelezhnikov <apodtele@gmail.com> |
