Jens Claudius 9950adcc11 * freetype2/include/freetype/internal/psaux.h: (enum T1_TokenType_):
add T1_TOKEN_TYPE_KEY. (struct T1_FieldRec_) add `dict'. Add macros
T1_FIELD_DICT_FONTDICT and  T1_FIELD_DICT_PRIVATE. Change T1_NEW_XXX and
T1_FIELD_XXX macros to take the dictionary where the PS keywords is
expected as an additional argument.

* freetype2/src/cid/cidload.c: (T1_FieldRec): Adjust invocations
of T1_FIELD_XXX.

* freetype2/src/cid/cidtoken.h: Adjust invocations of T1_FIELD_XXX.

* freetype2/src/psaux/psobjs.c: Add macro FT_COMPONENT for tracing.
(ps_parser_to_token): Report a PostScript key as T1_TOKEN_TYPE_KEY
instead as T1_TOKEN_TYPE_ANY. (ps_parser_load_field): Make sure a token
that should be a string or name is a string or name indeed. Avoid
memory leak if a keyword has been already encountered and its value
is overwritten.

* freetype2/src/type1/t1load.c: (T1_FieldRec): Adjust invocations of
T1_FIELD_XXX. (parse_dict): Ignore keywords that occur in the wrong
dictionary (e.g., in Private instead of FontDict).

* freetype2/src/type1/t1tokens.h: Adjust invocations of T1_FIELD_XXX.

Werner Lemberg c011f4cba1 The Type 1 parser now skips over top-level procedures as required
for a `Simplified Parser'.  This makes the parser more robust as it
doesn't poke around in PostScript code.  Additionally, it makes the
FontDirectory hackery in src/type1/t1load.c unnecessary.

* src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
(skip_literal_string): Add FT_Error as return value.
Handle escapes better.
(skip_string): Add FT_Error as return value.
Don't set `parser->error' but return error code directly.
(skip_procedure): New function.
(ps_parser_skip_PS_token): Handle procedures.
Update code.
(ps_parser_to_token): Update code.
(ps_parser_load_field_table): Handle bbox entries also.

* src/type1/t1load.c (parse_dict): Remove FontDirectory hackery.
Add commented-out code for synthetic fonts.

        src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

David Turner c13e75fb1b * src/base/ftutil.c: ft_mem_alloc and related functions now return an
error if a negative size is passed in parameters.

    * src/cache/ftccache.c: make ftc_node_destroy FT_BASE_DEF, it needs to
    be exported for rogue clients

    * src/pshinter/pshglob.c: prevent problems with malformed fonts which
    have an odd number of blue values (these are broken according to the
    specs).

    * src/cff/cffload.c, src/type1/t1load.c: modify the loaders to force
    even-ness of 'num_blue_values'. Also change the CFF loader so that
    invalid entries in index files are ignored.

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.

documentation of `outline' field.

* src/sfnt/sfobjc.s: Inckude FT_INTERNAL_DEBUG_H.

* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
2006-02-15 06:05:52 +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.
2006-01-31 20:17:42 +00:00

(cid_face_init), src/pfr/pfrobjs.c (pfr_face_init), src/type1/t1objs.c
(T1_Face_Init): Set face->height to
MAX(1.2 * units_per_EM, ascender - descender).

`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 7596fd3a46 * src/*/module.mk (.PHONY): Add. 2006-01-28 16:29:29 +00:00
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 !!
2006-01-27 12:11:22 +00:00
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.

* src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c,
src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c,
src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c:
Set the font metrics.
s/index/strike_index/.

* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
files were committed.  Just a catch-up.
(PS_Conv_ToFixed): Remove the `goto'.
(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.
