Werner Lemberg 2429dc3d7c Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option.
This controls whether the old FreeType CFF engine gets compiled into
FreeType.  It is now disabled by default.

Werner Lemberg 06474c3e5b [cff] Add a new Type 2 interpreter and hinter.
This work, written by Dave Arnold <darnold@adobe.com> and fully
integrated into FreeType by me, is a donation by Adobe in
collaboration with Google.  It is vastly superior to the old CFF
engine, and it will replace it soon.  Right now, it is still off by
default, and you have to explicitly select it using the new
`hinting-engine' property of the cff driver.

For convenience, (most of) the new files are committed separately.

* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
* include/freetype/ftcffdrv.h: New file to access CFF driver
properties.
* include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error
code.
* include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',
and `cf2interp'.

* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
and `no_stem_darkening'.
* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.

* src/cff/cff.c: Include new files.
* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
`hinting-engine' and `no-stem-darkening' properties (only the Adobe
engine listens to them).
* src/cff/cffgload.c: Include `cf2ft.h'.
(cff_decoder_prepare): Initialize `current_subfont'.
(cff_build_add_point): Handle Adobe engine which uses 16.16
coordinates.
(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
separately.
Choose rendering engine based on `hinting_engine' property.
* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
engine.
* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
(cff_driver_init): Set default property values.

* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.

* src/cff/cf2*.*: New files, containing the Adobe engine.
2013-04-13 18:53:28 +02:00
Werner Lemberg 89f5064765 */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
FT_Err_XXX and friends are no longer directly used in the source
code.
2013-03-14 17:50:49 +01:00
Werner Lemberg e3c9301581 */*: Use FT_Err_Ok only.
This is a purely mechanical conversion.
2013-03-14 11:21:17 +01:00
Werner Lemberg 059bc335ce */*: Use `FT_THROW'.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.
2013-03-14 10:27:35 +01:00

index handling to load both pure CFFs with multiple subfonts and
OTCs (with multiple faces where each face holds exactly one
subfont).
* src/cff/cffobjs.c (cff_face_init): Updated.

Too serious check of errors by `FT_CMap_New' since 2010-07-04
is fixed. Reported by Tor Andersson.

minimum character code passed by a legacy rogue client by...
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
This.  It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
undefined (thus the rogue client compatibility is not required).

selection or synthesis of Unicode cmap subtable when the charmap
index exceeds FT_MAX_CHARMAP_CACHEABLE.

earlier one.
(find_variant_selector_charmap): When UVS charmap is found after
FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
(FT_Select_Charmap): When a charmap matching with requested
encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Set_Charmap): When a charmap matching with requested
charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Get_Charmap_Index): When a requested charmap is found
after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
index.

Suzuki, Toshiya (鈴木俊哉) 0c0db3eb48 * src/cff/cffobjs.c: replace 0x4F54544FL by TTAG_OTTO 2008-09-18 04:36:56 +00:00
Werner Lemberg bd48d35bf8 Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set. 2008-07-16 07:05:11 +00:00
Werner Lemberg 3d2f06f399 Handle CID-keyed fonts wrapped in a SFNT (with cmaps) correctly.
* src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
Invert sids table only if `pure_cff' is set.
* src/cff/cffload.h: Udpated.

* src/cff/cffobjs.c (cff_face_init): Updated.
2008-07-16 06:13:34 +00:00
Werner Lemberg 5b631d894c * src/cff/cffobjs.c (cff_face_init): Compute final
`dict->units_per_em' value before assigning it to
`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are be
scaled incorrectly if the font matrix is non-standard.  This fixes
Savannah bug #23630.

* docs/CHANGES: Updated.
2008-06-19 16:23:43 +00:00
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 048b756389 * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
integer part is zero.
2008-04-13 05:55:36 +00:00
Werner Lemberg 210d61894b Fix support for subsetted CID-keyed CFFs.
* include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
FT_IS_CID_KEYED): New macros.

* src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
maximum CID value in CID-keyed CFFs.
Handle FT_FACE_FLAG_CID_KEYED flag.

* docs/CHANGES: Document it.


Fix CFF font matrix calculation and improve precision.

* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
part is zero.
(cff_parse_font_matrix): Simplify computation of `units_per_em';
this prevents overflow also.


Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.

* src/cid/cidriver.c: Include FT_SERVICE_CID_H.
(cid_get_ros): New function.
(cid_service_cid_info): New service structure.
(cid_services): Register it.
2008-04-01 05:55:48 +00:00
Werner Lemberg 1e1b6dff54 * src/pfr/pfrcmap.c: Include pfrerror.h.
* src/autofit/afindic.c: Add some external declarations to pacify
`make multi' compilation.

* src/cid/cidgload.c (cid_load_glyph): Pacify compiler.

* src/cff/cffdrivr.c (cff_ps_get_font_info), src/cff/cffobjs.c
(cff_strcpy), include/freetype/internal/ftmemory.h (FT_MEM_STRDUP),
src/autofit/aflatin.c (af_latin_hints_compute_edges),
src/autofit/afcjk.c (af_cjk_hints_compute_edges), src/sfnt/ttmtx.c
(tt_face_get_metrics), src/base/ftobjs.c (open_face)
[FT_CONFIG_OPTION_INCREMENTAL]: Fix compilation with C++ compiler.

* docs/release: Mention test compilation targets.

Werner Lemberg 442bfb8913 Formatting, copyright years, s/memcpy/ft_memcpy/. 2007-02-12 21:44:10 +00:00
David Turner c0f9c4aadd introduce ft_mem_dup, ft_mem_strdup and ft_mem_strcpyn, and the corresponding
macros to use them (e.g. FT_STRDUP, FT_DUP and FT_STRCPYN)

modify the code to use them instead of raw mallocs/strcpy
2007-02-12 14:55:03 +00:00
Werner Lemberg 8c4120d0a3 Fix various compiler warnings.
* src/truetype/ttdriver.c (tt_size_select), src/cff/cffobjs.h,
src/cff/cffobjs.c (cff_size_request), src/type42/t42objs.h:
s/index/strike_index/.
