David Turner 6cda6c064f * src/bdf/bdflib.c: fixed a bug with zero-width glyphs
this patch comes from the Debian package for libfreetype6 !!
    How come nobody mentions this on the devel list ??
2006-02-23 12:37:18 +00:00
Wu, Chia-I (吳佳一) 890f807a7b * include/freetype/ftoutln.h (enum FT_Orientation): New value
`FT_ORIENTATION_NONE'.

* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
ft_contour_enclosed, ft_outline_get_orientation): Another version of
`FT_Outline_Get_Orientation'.  This version differs from the public
one in that each part (contour not enclosed in another contour) of the
outline is checked for orientation.
(FT_Outline_Embolden): Use `ft_outline_get_orientation'.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and
use bitmap's embolden routine when the outline one failed.

Werner Lemberg 5edafed12a Clean-ups, copyright years, formatting. 2006-02-22 08:23:35 +00:00
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.
2006-02-22 07:59:35 +00:00
David Turner 0b5dc4df88 * include/freetype/ftmodapi.h, include/internal/ftserv.h,
include/internal/services/svtteng.h, src/base/ftobjs.c,
    src/truetype/ttdriver.c:

    adding a new API named FT_Get_TrueType_Engine_Type to determine
    wether we have a patented, unpatented or unimplemented TrueType
    bytecode interpreter.

    the FT_Get_Module_Flags API was removed consequently.
2006-02-21 22:36:23 +00:00
David Turner c093db9d06 * src/sfnt/sfmtx.c: disabling memory optimization when
FT_CONFIG_OPTION_OLD_INTERNALS is used. This is because libXfont
    is directly accessing the HMTX data. Grrrrr....
2006-02-21 17:06:35 +00:00
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
Werner Lemberg d41aecdbc0 formatting, doc improvements 2006-02-21 08:08:14 +00:00
David Turner dd0f3609d7 * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,
src/sfnt/ttsbit.h, src/sfnt/ttsbit.c: moving the definition
        of 'set_sbit_strike' and 'load_sbit_metrics' to their 2.1.8
        location. This is used to support binary compatibility with
        the X.Org server's libXfont library.

        note that this disables memory optimizations for the embedded
        bitmap loader.Sigh....

Werner Lemberg f145e312df Formatting, copyright years, minor doc fixes. 2006-02-19 16:12:18 +00:00
David Turner 0880ac333a * builds/unix/unix-cc.in: don't filter-out exported functions
anymore, this is used to ensure that all FT_BASE internal
    functions are available for dynamic linking

    * include/freetype/ftcache.h, src/cache/ftcbasic.c,
    src/cache/ftccmap.c: try to revive old functions of the
    cache sub-system. We also try to support FTC_ImageCache_Lookup
    and FTC_ImageCache_SBit with legacy signatures through a gross
    hack (hope it works)
2006-02-17 17:23:13 +00:00
Werner Lemberg 1fae66950b * devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.

      src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c:

    massive changes to the internals to respect the internal object layouts
    and exported functions of FreeType 2.1.7. Note that the cache sub-system
    cannot be fully retrofitted, unfortunately.
2006-02-16 22:45:31 +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.
2006-02-15 06:05:52 +00:00
Wu, Chia-I (吳佳一) 3dc0018174 * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo. 2006-02-14 13:36:28 +00:00
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) e0decd1e27 * src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of
code...
2006-02-14 07:20:06 +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.

Wu, Chia-I (吳佳一) 4c507ffa80 * src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug...
* src/autofit/aflatin.c (af_latin_metrics_init_widths): Use
AF_LatinMetricsRec as the dummy metrics because we cast the metrics to
it later in `af_latin_hints_link_segments'.
2006-02-11 13:22:37 +00:00
Wu, Chia-I (吳佳一) f9a69132a7 * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define
to enable autofit CJK script support. (#define'd by default)

* src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro.

* src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure that
`edge_distance_threshold' is always set.
(af_latin_hints_link_segments): Potential divide by 0 bug.
Use latin constant in the scoring formula.

* src/autofit/afcjk.c: Minor updates due to the above three changes.

* docs/TODO, docs/CHANGES: Updated.

Wu, Chia-I (吳佳一) 4cdb45c01e Introduce experimental autofit CJK module based on akito's autohint
patch.  You need to #define AF_MOD_CJK in afcjk.c to enable it.

* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,
src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:
Add CJK module based on akito's autohint patch.

* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the
overlap length of the segments.  (AF_SEGMENT_LEN, AF_SEGMENT_DIST):
New macros.

* src/autofit/aflatin.h (af_latin_metrics_init_widths),
src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'.
Use the character given by the caller.
(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale
the thresholds.

* src/autofit/afloader.c (af_loader_load_g): Respect
AF_SCALER_FLAG_NO_ADVANCE.
2006-02-09 14:17:04 +00:00
Werner Lemberg 6be99f9104 * src/cid/cidparse.c (cid_parse_new): Remove shadowing variable.

2006-02-01 05:14:25 +00:00
Werner Lemberg 59939244ad Implement new, simplified module selection. With GNU make it is now
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.

This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.

Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.

* modules.cfg: New file.

* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.

* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables.  Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.

* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files.  We no longer use make's `wildcard' function for this.

* Makefile (USE_MODULES): Remove.  Update all users.
(OBJ_DIR): Define it here.

* src/*/module.mk: Change

    make_module_list: foo
    foo: ...

to

    FTMODULE_H_COMMANDS += FOO
    define FOO
    ...
    endef

in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.

* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.

* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.

* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.

* include/freetype/config/ftmodule.h: Add comments -- this file is
no longer used if FreeType is built with GNU make.

* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
Other minor updates.

* modules.txt: Removed.  Contents included in `modules.cfg'.


* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.

* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
[FT_STRICT_ALIASING]: Implement.

Wu, Chia-I (吳佳一) 98d802b83a * include/freetype/internal/t1types.h (AFM_FontInfo),
src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox',
`Ascender', and `Descender' from an AFM.

* src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.

* include/freetype/freetype.h (FT_FaceRec): Mention that fields may be
changed after file attachment.
2006-01-31 07:01:24 +00:00

Werner Lemberg f6a25503c5 * devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.

* src/autofit/module.mk (add_autofit_module), src/bdf/module.mk
(add_bdf_module), src/type42/module.mk (add_type42_driver): Fix
whitespace.

* src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv
renderer classes.

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

Wu, Chia-I (吳佳一) bcc438b15e * include/freetype/freetype.h (FT_Select_Size): Rename the second
argument from `idx' to `strike_index'.
(FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of
this enum.

* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,
FT_REQUEST_HEIGHT): New macros to get the width and height of a
request, in fractional pixels.

* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
FT_Request_Metrics): New base functions to set the font metrics.  They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.

* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL.  That is, drivers
should set the metrics themselves.
(FT_Match_Size): Round before matching.  This was what we did and it
does cause some problems without rounding.

* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
(tt_size_select): Set the font metrics.
s/index/strike_index/.
The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected.  This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.

* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
(tt_size_request): Set the font metrics.
Call cff_size_select/tt_size_select when some strike is matched.

(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.

* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
advertised metrics in `available_sizes' are different from those
actually used.

        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.

Wu, Chia-I (吳佳一) a0911343ee Major update to distinguish between unsorted and overlapped segments
for cmap format 4.  For overlapped but sorted segments, which is
previously considered unsorted, we still use binary search.

* src/sfnt/ttcmap.h (struct  TT_CMapRec_): Replace `unsorted' by
`flags'.
(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.

* src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.
(struct TT_CMap4Rec_): Remove `old_charcode' and `table_length'.
(tt_cmap4_reset): Removed.
(tt_cmap4_init): Updated accordingly.
(tt_cmap4_next): Updated accordingly.
Take care of overlapped segments.
(tt_cmap4_validate): Make sure the subtable is large enough.
Do not check glyph_ids because some fonts set the length wrongly.
Also, when all segments have offset 0, glyph_ids is always invalid. It
does not cause any problem so far only because the check misses
equality.
Distinguish between unsorted and overlapped segments.
(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions to
do "charcode => glyph index" by linear/binary search.
(tt_cmap4_char_index, tt_cmap4_char_next): Use
tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.

Werner Lemberg 8eacad6daa * freetype2/src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a
font to have no `head' table if tables `SING' and `META' are
present; this is to support `SING Glyphlet'.

`SING Glyphlet' is an extension to OpenType developed by Adobe
primarily to facilitate adding supplemental glyphs to an OpenType
font (with emphasis on, but not necessariy limited to, gaiji to a
CJK font).  A SING Glyphlet Font is an OpenType font that contains
the outline(s), either in a `glyf' or `CFF' table, for a glyph;
`cmap', `BASE', and `GSUB' tables are present with the same format
and functionaliy as a regular OpenType font; there are no `name',
`head', `OS/2', and `post' tables; there are two new tables, `SING'
which contains details about the glyphlet, and `META' which contains
metadata.

Further information on the SING Glyphlet format can be found at:

  http://www.adobe.com/products/indesign/sing_gaiji.html

* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New
