LATEST CHANGES BETWEEN 2.0.6 and 2.0.5 |
|
|
|
|
|
|
|
|
|
*** IMPORTANT BUG FIXES: |
|
|
|
|
|
|
|
|
|
- it wasn't possible to load embedded bitmaps when the auto-hinter was |
|
|
|
|
used. This is now fixed.. |
|
|
|
|
|
|
|
|
|
- the TrueType font driver didn't load some composites properly |
|
|
|
|
(the sub-glyphs were slightly shifted, and this was only noticeable |
|
|
|
|
when using monochrome rendering) |
|
|
|
|
|
|
|
|
|
- Various fixes to the auto-hinter. They merely improve the output of |
|
|
|
|
sans-serif fonts. Note that there are still problems with serifed |
|
|
|
|
fonts and composites (accented characters). |
|
|
|
|
|
|
|
|
|
- all scalable font drivers mistakenly returned un-fitted glyph advances |
|
|
|
|
when hinting was requested. This created problems for a number of layout |
|
|
|
|
applications. This is a very old bug that got undetected mainly because |
|
|
|
|
most test/demo program perform rounding explicitely or implicitely |
|
|
|
|
(through the cache). |
|
|
|
|
|
|
|
|
|
- FT_Glyph_ToBitmap did mistakenly modify the source glyph in certain cases. |
|
|
|
|
|
|
|
|
|
- "glnames.py" still contained a bug that made FreeType return invalid |
|
|
|
|
names for certain glyphs. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
*** IMPORTANT UPDATES & NEW FEATURES: |
|
|
|
|
|
|
|
|
|
- important updates to the Mac-specific parts of the library. |
|
|
|
|
|
|
|
|
|
- The caching sub-system has been completely re-designed, and its API has |
|
|
|
|
evolved (the old one is still supported for backwards). |
|
|
|
|
|
|
|
|
|
The documentation for it will be completed on the next release though.. |
|
|
|
|
For now, you're encouraged to continue using the old API |
|
|
|
|
|
|
|
|
|
- A new charmap cache is provided too. See FTC_CMapCache. This is useful |
|
|
|
|
to perform character code -> glyph index translations quickly, without |
|
|
|
|
the need for an opened FT_Face.. |
|
|
|
|
|
|
|
|
|
- A NEW POSTSCRIPT HINTER module has been added to support native hints in |
|
|
|
|
the following formats: Postscript Type 1, Postscript CID and CFF/CEF. |
|
|
|
|
|
|
|
|
|
CHECK THIS OUT !! Note that the auto-hinter produces better results for |
|
|
|
|
a number of badly-hinted fonts (mostly auto-generated ones) though.. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- A memory debugger is now part of the standard FreeType sources. To |
|
|
|
|
enable it, define FT_DEBUG_MEMORY in <freetype/config/ftoption.h>, |
|
|
|
|
and recompile the library. |
|
|
|
|
|
|
|
|
|
Now, define the _environment_ variable FT_DEBUG_MEMORY and run any |
|
|
|
|
program using FreeType. When the library is exited, a summary of |
|
|
|
|
memory footprints and eventual leaks will be displayed.. |
|
|
|
|
|
|
|
|
|
this works transparently with _any_ program that uses FreeType.. |
|
|
|
|
you'll need _lots_ of memory to use this however (allocated blocks |
|
|
|
|
are never released to the heap to detect double deletes easily) |
|
|
|
|
|
|
|
|
|
*** OTHER: |
|
|
|
|
|
|
|
|
|
- we're aware of subtle differences between the output of FT 1 and FT 2 |
|
|
|
|
when it comes to monochrome TrueType-hinted glyphs. These are most |
|
|
|
|
probably due to small differences in the monochrome rasterizers and |
|
|
|
|
will be worked out in an upcoming release. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- the next release will be named FreeType 2.1, and will include a |
|
|
|
|
_major_ rework of the library's internals, both to make the source |
|
|
|
|
code more consistent, readable, etc.. as well as to implement new |
|
|
|
|
features like: |

The documentation for it is not yet completed, sorry. For now, you |
|
|
|
|
are encouraged to continue using the old API. However, the ftview |
|
|
|
|
demo program in the ft2demos package has already been updated to use |
|
|
|
|
the new caching functions. |
|
|
|
