-
-2018-04-10 Nikolaus Waxweiler <address@hidden>
-
- * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
- modernization measures.
-
- 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.

- in above.
-
-2018-04-01 Werner Lemberg <address@hidden>
-
- * builds/toplevel.mk (work): Use $(SEP).

-
- [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.
-
- * src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
- `cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
- hinting.
-
-2018-01-06 Werner Lemberg <address@hidden>
-
- Add `FT_Done_MM_Var'.
-
- This is necessary in case the application's memory routines differ
- from FreeType. A typical example is a Python application on Windows
- that calls FreeType compiled as a DLL via the `ctypes' interface.
-
- * include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare
- and define.
-
- * docs/CHANGES: Updated.
-
-2018-01-03 Werner Lemberg <address@hidden>
-
- [truetype] Round offsets of glyph components only if hinting is on.
-
- * src/truetype/ttgload.c (TT_Process_Composite_Component): Implement
- it.
-
-2018-01-03 Werner Lemberg <address@hidden>
-
- * src/truetype/ttgxvar.c (ft_var_to_design): Remove dead code.
-
- This is a better fix than the previous commit, which is now

- 0xFA), and a second one for higher byte 0x01 (just for character

-
- 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.

- LIGHT NORMAL

- TrueType Auto v40
- CFF Adobe Adobe
- Type 1 Adobe Adobe

-
- [cff, truetype] Adjust behaviour of named instances.
-
- This commit completely separates the interaction between named

-
- [psaux] Extend Adobe interpreter (hsbw, sbw).

- [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.

+
+ * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
+ modernization measures.
+
+ 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.

+ 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.

+
+2017-09-25 Ewald Hew <address@hidden>
+
+ [psaux] Extend Adobe interpreter (hsbw, sbw).

+
+2017-09-25 Ewald Hew <address@hidden>
+
+ [psaux] Add Type 1 operations to Adobe CFF interpreter.
+

+
+ closepath
+ vstem3
+ hstem3
+ seac

+
+2017-09-25 Ewald Hew <address@hidden>
+
+ [type1] Fixes for rendering.
+
+ The Type 1 advance width calculation passes null for glyph slot,

+
+ * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a

+
+ Synthesize a `SubFont' object for Type 1 fonts. This is used in the

+ be used in either mode.
+
+ * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy

+
+ [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 <address@hidden>
+
+ [build] Declutter Visual C++ 2010-2017 project.
