|
e1339133 | 2020-06-08 13:31:55 | 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. | |
|
4eee1340 | 2020-05-18 09:16:12 | Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete. | |

 |
f2b64583 | 2019-07-04 14:04:52 | [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it. | |
|

9159128a | 2019-05-29 07:45:54 | Silence gcc 7's fall-through warnings in `switch' blocks. Instead of an intentionally missing `break' statement there must be a comment line containing `fall through' (and nothing else) right before the next `case' statement. See https://stackoverflow.com/questions/45129741/gcc-7-wimplicit-fallthrough-warnings-and-portable-way-to-clear-them | |
|
03f3f8ab | 2019-05-13 06:53:19 | * src/psaux/psfont.c (cf2_font_setup): Fix compiler warning. | |

|
6a4718a3 | 2019-03-05 17:25:19 | Fix use of uninitialized memory. * 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. | |

b75abeb5 | 2019-01-08 20:51:39 | [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'. | |

a9af6914 | 2018-09-25 09:10:09 | 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. | |

b9bd2d14 | 2017-11-22 12:32:47 | [psaux] Fix CFF advance widths. (#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer. Remove unused fields. * src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy to reference. Remove unused. * src/psaux/psft.c (cf2_setGlyphWidth): Update code. | |

cdab9cfa | 2017-10-21 16:36:49 | [psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251) 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>: Ensure we are on the top level charstring before rewinding. | |
|
dff40d03 | 2017-10-12 18:13:21 | Add T1_CONFIG_OPTION_OLD_ENGINE configuration option. This controls whether the old Type 1 engine gets compiled into FreeType.

Minor code changes. | |
|
78df3c27 | 2017-10-12 18:13:08 | Extract width parsing from Type 1 parser. Duplicate the fast advance width calculations from the old parser. This is to facilitate adding options for compiling out the old parser. * src/psaux/t1decode.{c,h} (t1_decoder_parse_metrics): New function. * include/freetype/internal/psaux.h (T1_Decoder_Funcs): New entry `parse_metrics'. * src/psaux/psauxmod.c: Set the new entry. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Separate conditional for selecting engine. | |

|
37ed70f6 | 2017-09-25 06:59:26 | 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'). | |
|
6eb03f8f | 2017-09-25 06:49:41 | 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. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call. | |

d23affe1 | 2017-09-25 06:22:52 | 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. | |
|
9428ee42 | 2017-09-25 06:15:46 | Prepare for Type 1 mode.
