Werner Lemberg 7d9c189ac2 * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
support for bit 8 in the `OS/2' table.  MS is already using this;
hopefully, this becomes part of OpenType 1.5.
Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
(WWS_SUBFAMILY).

Werner Lemberg 33db39e292 * src/sfnt/sfobjs.c (sfnt_load_face): Undo change from 2007-04-28.
Fonts without a cmap must be handled correctly by FreeType (anything
else would be a bug).

David Turner f3050059dd * src/sfnt/sfobjs.c (tt_face_get_name): support some function
which report their English names through an Apple Roman
        (platform,encoding) pair, with language_id != English

        if the font uses another name entry with language_id == English,
        it will be selected correctly though.

        * src/truetype/ttobjs.c: add unpatent-hinting selection for
        "mingli.ttf"

Wu, Chia-I (吳佳一) facd9af542 * modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI
compatibility.

* src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak.

* src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,
tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit
loading. (only tested with bit aligned sbit with x_pos == 0)

* src/truetype/ttpload.c (tt_face_load_hdmx,
tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: hdmx is not actually
used.

David Turner 1ae134a233 * src/sfnt/sfobjs.c (sfnt_face_load): fixed silly bug that
prevented embedded bitmaps from being correctly listed and used

    * src/pfr/pfrsbit.c: fixed handling of character advances
2006-02-21 16:50:17 +00:00
Wu, Chia-I (吳佳一) 0d565fdc1d * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove
unused `max_points' and `max_contours'.

* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.

* include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused
`max_components'.

* src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused
`loadSize' and `loadStack'.

* src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),
src/sfnt/ttload.c (tt_face_load_maxp): Update.

* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
defined.

* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)

For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'.  Here, we try to
make this work for _all_ tables.

* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit.  Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.

* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Pretty trace messages.

* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from
`eblc'.

* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
(load_format_20, load_format_25, tt_face_get_ps_name): Use
face->max_profile.numGlyphs, instead of face->root.num_glyphs.
2006-02-15 07:44:31 +00:00
Werner Lemberg 5225402a52 * include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in
documentation that negative strength values are possible.
Give an example call.

* include/freetype/freetype.h (FT_GlyphSlotRec): Improve
documentation of `outline' field.

* src/sfnt/sfobjc.s: Inckude FT_INTERNAL_DEBUG_H.
* src/sfnt/sfdriver.c: Include ttmtx.h.

* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.

Wu, Chia-I (吳佳一) 9a2b3b6d55 * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply
return error if table is missing.
Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.

* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
tables.  The last change makes Mac bitmap-only font not load and this
fixes it.

* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error
when FT_CONFIG_OPTION_INCREMENTAL is defined.
2006-02-14 08:37:03 +00:00
Wu, Chia-I (吳佳一) 35222ff7bb Clean up the SFNT_Interface. In this final pass, `load_hmtx' is
splitted from `load_hhea'.

* include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,
src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.

* src/sfnt/sfobjs.c (sfnt_load_face): Update.
2006-02-14 07:25:57 +00:00
Wu, Chia-I (吳佳一) 65863a5712 Clean up the SFNT_Interface. In this pass, we want to treat the font
directory (offset table and table directory) as a normal table like
the others.  This also means that TTC is no longer recognized there,
but in `init_face'.

* include/freetype/internal/sfnt.h (SFNT_Interface),
src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
combined and renamed to `load_font_dir'.

* src/sfnt/ttload.h, src/sfnt/ttload.c:
s/sfnt_dir_check/check_table_dir/.
`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
and renamed to `tt_face_load_font_dir'.

* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
2006-02-14 07:01:29 +00:00
Wu, Chia-I (吳佳一) f5aa47beb0 Clean up the SFNT_Interface. Table loading functions are now named
after the tables' tags;  `hdmx' is TrueType-specific and thus the code
is moved to the truetype module; `get_metrics' is moved here from the
truetype module so that the code can be shared with the cff module.

This pass involves no real changes.  That is, the code is moved
verbatim mostly.  The only exception is the return value of
`tt_face_get_metrics'.

* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,
src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,
src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.

* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading
and parsing code is moved here.
Move `tt_face_get_metrics' here from the truetype module.  The return
value is changed from `void' to `FT_Error'.

* include/freetype/internal/fttrace.h: New trace: ttmtx.

* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
parsing code is moved here.
New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'.
`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

* src/cff/cffgload.c, src/cff/cffobjs.c: Update.

* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!

David Turner 89a2a4b531 * include/freetype/config/ftoption.h,
include/freetype/config/ftstdlib.h,
        include/freetype/internal/tttypes.h,
        src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c,
        src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c:

        Added support for an embedded 'BDF ' table within SFNT-based
        bitmap font files. This is used to store atoms & properties from
        the original BDF fonts that were used to generate the font file.

        the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
        and is used to implement FT_Get_BDF_Property for these font files.

        At the moment, this is still experimental, the BDF table format isn't
        cast into stone yet.

2005-02-28 22:09:07 +00:00
David Turner e5680279b2 * many, many files: several memory optimizations were implemented to
drastically reduce the heap usage of FreeType, especially in the case
  of memory-mapped files. The idea is to avoid loading and decoding tables
  in the heap, and instead access the raw data whenever possible (i.e.
  when it doesn't compromise performance).

  This had several impacts: first, opening vera.ttf uses a ridiculous amount
  of memory (when the FT_Library footprint is accounted for), until you start
  loading glyphs. Even then, you'll save at least 20 Kb compared to the non
  optimized case. performance of various operations, including open/close
  has also been dramatically improved.

  More optimisations to come. The auto-hinter eats memory like crazy? This
  must be stopped...
