Alexei Podtelezhnikov a692170a23 Call it fixed-point. 2013-01-12 19:17:05 -05:00
Werner Lemberg 83c0ebabc2 Fix conditional compilation.
* include/freetype/internal/ftcalc.h (FT_MulDiv_No_Round): Don't
enclose with `TT_USE_BYTECODE_INTERPRETER'; we now need the function
elsewhere also.

* src/autofit/afcjk.h: Use AF_CONFIG_OPTION_CJK.

* src/truetype/ttgload.c (tt_loader_init): Fix compiler warning.

* src/truetype/ttinterp.c (Ins_MSIRP): Fix compiler warning.

* src/truetype/ttinterp.h: Use
TT_CONFIG_OPTION_BYTECODE_INTERPRETER.

Werner Lemberg f79df78a53 Code beautification.
* src/type1/t1load.c (FT_INT_TO_FIXED): Removed.
Replace everywhere with INT_TO_FIXED.
(FT_FIXED_TO_INT): Move to ...
* include/freetype/internal/ftcalc.h (FIXED_TO_INT): Here.
Update all users.

Werner Lemberg e6e6eade04 Finish fix of scaling bug of CID-keyed CFF subfonts.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.

* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).

* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results.  This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.

* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.
Update all callers.
(cff_slot_load): Handling scaling of subfonts properly.

* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
(cff_parse_font_matrix): Use it.

* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
FT_ULong.

* docs/CHANGES: Document it.
2008-05-14 23:05:38 +00:00
Werner Lemberg 111b5aefca * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

David Turner effd15de89 - merging af_corner_XXX and psh_corner_XXX functions into ft_corner_XXX versions in ftcalc.c
- more auto-fitter debugging support
2006-11-02 17:21:02 +00:00
David Turner 6aa260ce61 support for "automatic unpatented hinting" added
we still need to determine the list of "trick" CJK fonts
that are going to toggle the bytecode interpreter instead
of the auto-hinter

    cannot be fully retrofitted, unfortunately.

David Turner ac6cc419df modified the TrueType interpreter to let it
use the new trigonometric functions provided in "fttrigon.h". This
        gets rid of some old 64-bit computation routines, as well as many
        warnings when compiling the library with the "long long" 64-bit
        integer type.

Werner Lemberg 5704f0c984 * include/freetype/internal/ftcalc.h: Move declaration of
FT_SqrtFixed() out of `#ifdef FT_LONG64'.

* src/base/ftcalc.c (FT_MulDiv, FT_MulFix, FT_DivFix): Various tiny
fixes related to rounding in 64-bits routines and
pseudo-"optimizations".
2001-05-09 20:57:45 +00:00
Werner Lemberg 3780273e3e * builds/unix/config.guess, builds/unix/config.sub: Updated to
latest versions from gnu.org.

* builds/compiler/gcc-dev.mk: Add `-Wno-long-long' flag.

* include/freetype/internal/ftcalc.h: Define FT_SqrtFixed()
uncoditionally.
* src/base/ftbbox.c: Include FT_INTERNAL_CALC_H.
Fix compiler warnings.
* src/base/ftcalc.c: Fix (potential) compiler warnings.

* src/base/ftcalc.c (FT_SqrtFixed): Corrected/optimized the 32-bit
fixed-point square root computation.  It is now used even with
64-bits integers, as it is _much_ faster than calling FT_Sqrt64 :-)
* src/base/ftbbox.c: Removed invalid "#include FT_BEZIER_H" line.
* src/base/ftbbox.c (BBox_Cubic_Check): Rewrote function to use
direct computations with 16.16 values instead of sub-divisions.  It
is now slower, but proves a point :-)
* src/raster/ftraster.c, src/smooth/ftgrays.c, src/base/ftbbox.c:
Fixed the bezier stack depths.
* src/base/ftcalc.c (FT_MulFix): Minor rounding fix.
* builds/beos: Added BeOS-specific files to the old build system
(no changes were necessary to support BeOS in the Jamfile though).
* ftconfig.h, ftoption.h: Updated "ftconfig.h" to detect 64-bit int
types on platforms where Autoconf is not available).  Also removed
FTCALC_USE_LONG_LONG and replaced it with
FT_CONFIG_OPTION_FORCE_INT64.
* builds/win32/freetype.dsp: Updated the Visual C++ project file.
Doesn't create a DLL yet.
* cffgload.c: Removed a compilation warning.
2001-04-26 13:34:36 +00:00
Werner Lemberg 90d9964ec9 * */*.h: Changed body inclusion macro names to start and end with
`__' (those which haven't converted yet).  Fixed minor conversion
issues.

* src/winfonts/winfnt.c: Updated to new header inclusion scheme.

* */*.[ch]: Changed source files to adhere to the new
* src/cff/cff.c, src/cff/rules.mk: Updated.

* */*.[ch]: Now using <ft2build.h> as the default build and setup
2000-12-09 00:45:38 +00:00
David Turner d3c8e064a5 - updating the header inclusion scheme to use <ft2build.h> by
default..

- created "builds/devel" to hold developer builds options
  for both Win32 and Unix

- fixed a bug in the winfonts driver, where the glyph image format
  wasn't set correctly..
2000-12-04 22:53:55 +00:00
David Turner 8fba32d2d6 introduced the new <freetype/config/ftbuild.h> file to determine
where is the top-level include directory for all public, configuration
and internal header files..
2000-11-30 23:12:33 +00:00
Werner Lemberg 90a0330142 All function comments are now removed from source files (and moved to the
header files if necessary).

Some minor fixes to have `make multi' run successfully (with gcc and g++).

Fixing compiler warnings.

Werner Lemberg f9b0375002 small formatting issues. 2000-09-11 22:50:13 +00:00
David Turner a8194a97db - added a new function called FT_SqrtFixed to compute the
16.16 square root of a 16.16 number (this could come handy
  in a later version of the auto-hinter)

- small fixes to the smooth renderer. It used to use way too
  much line segments when drawing beziers !!

Werner Lemberg bd5ae40006 Run g++ on the FreeType library. This should make the use of code in
C++ programs easier:

  Renamed FT_WordXX to FT_UIntXX.

  Changed a lot of void* to FT_Byte* if related to i/o streams -- FreeType
  always accesses streams byte-wise, so this makes sense IMHO.

  Added a lot of #ifdef __cplusplus to header files (and removed a few).

  Other minor syntax fixes (mostly casts).

  Replaced the variable `private' with `private_dict' -- `private' is
  reserved in C++.
2000-07-05 04:32:02 +00:00
Werner Lemberg 78575dc0d1 A lot of formatting.
Added more tracing levels.

More Makefile fixes.

Minor other changes.

David Turner bfe2f98f1f a new massive grunt work. Redefined the EXPORT_DEF,
EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to
let them take an argument..

This is needed to compile the library as a DLL on some platforms
that have different compiler conventions..
