Werner Lemberg fa437d8d3c [cff] Provide metrics variation service interface (#50196).
Only now I've got an OTF with an HVAR table for testing...

Werner Lemberg 5018477f4e Minor. 2014-12-07 08:17:12 +01:00
Werner Lemberg ffee64afb8 Better tracing of loaded glyphs.
Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").

* src/cff/cffdrivr.c (cff_glyph_load): Ditto.
* src/cff/cffgload.c (cff_decoder_prepare): Improve tracing
messages.

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.

* devel/ftoption.h, include/freetype/config/ftoption.h
(CFF_CONFIG_OPTION_OLD_ENGINE): New macro.

* src/cff/cffdrivr.c (cff_property_set), src/cff/cffgload.c
(CFF_Operator, cff_argument_counts, cff_builder_add_point,
cff_operator_seac, cff_decoder_parse_charstrings, cff_slot_load),
src/cff/cffgload.h, src/cff/cffobjs.c (cff_driver_init): Use
CFF_CONFIG_OPTION_OLD_ENGINE to guard the affected code.

* docs/CHANGES: Updated.

Werner Lemberg f6aa089f12 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code. 2013-05-10 07:58:47 +02:00
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.

Werner Lemberg fc185ef41a Add framework for CFF properties.
* include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7):
New macro.

* src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H.
(cff_property_set, cff_property_get): New function, still empty.
Define `cff_service_properties' service.
Update `cff_services'.

* src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H.
(CFF_SERVICE_PROPERTIES_GET): New macro.
CffModulePIC: Add `cff_service_properties'.

Werner Lemberg e3c9301581 */*: Use FT_Err_Ok only.
This is a purely mechanical conversion.
