◆ hb_subset_input_t
hb_subset_input_t:
Things that change based on the input. Characters to keep, etc.
Definition at line 41 of file hb-subset.h.
◆ hb_subset_plan_t
hb_subset_plan_t:
Contains information about how the subset operation will be executed. Such as mappings from the old glyph ids to the new ones in the subset.
Definition at line 50 of file hb-subset.h.
◆ hb_subset_flags_t
hb_subset_flags_t: @HB_SUBSET_FLAGS_DEFAULT: all flags at their default value of false. @HB_SUBSET_FLAGS_NO_HINTING: If set hinting instructions will be dropped in the produced subset. Otherwise hinting instructions will be retained. @HB_SUBSET_FLAGS_RETAIN_GIDS: If set glyph indices will not be modified in the produced subset. If glyphs are dropped their indices will be retained as an empty glyph. @HB_SUBSET_FLAGS_DESUBROUTINIZE: If set and subsetting a CFF font the subsetter will attempt to remove subroutines from the CFF glyphs. @HB_SUBSET_FLAGS_NAME_LEGACY: If set non-unicode name records will be retained in the subset. @HB_SUBSET_FLAGS_SET_OVERLAPS_FLAG: If set the subsetter will set the OVERLAP_SIMPLE flag on each simple glyph. @HB_SUBSET_FLAGS_PASSTHROUGH_UNRECOGNIZED: If set the subsetter will not drop unrecognized tables and instead pass them through untouched. @HB_SUBSET_FLAGS_NOTDEF_OUTLINE: If set the notdef glyph outline will be retained in the final subset. @HB_SUBSET_FLAGS_GLYPH_NAMES: If set the PS glyph names will be retained in the final subset. @HB_SUBSET_FLAGS_NO_PRUNE_UNICODE_RANGES: If set then the unicode ranges in OS/2 will not be recalculated. @HB_SUBSET_FLAGS_NO_LAYOUT_CLOSURE: If set don't perform glyph closure on layout substitution rules (GSUB). Since: 7.2.0. @HB_SUBSET_FLAGS_OPTIMIZE_IUP_DELTAS: If set perform IUP delta optimization on the remaining gvar table's deltas. Since: 8.5.0 @HB_SUBSET_FLAGS_IFTB_REQUIREMENTS: If set enforce requirements on the output subset to allow it to be used with incremental font transfer IFTB patches. Primarily, this forces all outline data to use long (32 bit) offsets. Since: EXPERIMENTAL
List of boolean properties that can be configured on the subset input.
Since: 2.9.0
