06474c3e	2013-04-13T18:53:28	[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.

03b3da8b	2010-03-02T13:00:55	Improve CFF string (especially glyphname) lookup performance. We do this by avoiding memory allocation and file I/O. This is Savannah patch #7104. * src/cff/cfftypes.h: Include PS cmaps service and FT_INTERNAL_POSTSCRIPT_HINTS_H. (CFF_SubFontRec): Remove `num_local_subrs'. (CFF_FontRec): Add `num_strings', `strings', and `string_pool' fields. Remove `string_index' and `num_global_subrs' fields.

[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.
