public class TtfTableGLYF.CompositeDescript
extends TtfTableGLYF.Descript

Compound glyphs are glyphs made up of two or more component glyphs. A compound glyph description begins like a simple glyph description with four words describing the bounding box. It is followed by n component glyph parts. Each component glyph parts consists of a flag entry, two offset entries and from one to four transformation entries.

Type	Name	Description
uint16	flags	Component flag
uint16	glyphIndex	Glyph index of component
int16, uint16, int8 or uint8	argument1	X-offset for component or point number; type depends on bits 0 and 1 in component flags
int16, uint16, int8 or uint8	argument2	Y-offset for component or point number type depends on bits 0 and 1 in component flags
transformation option	One of the transformation options from Table 19

Component flags

Flags	Bit	Description
ARG_1_AND_2_ARE_WORDS	0	If set, the arguments are words; If not set, they are bytes.
ARGS_ARE_XY_VALUES	1	If set, the arguments are xy values; If not set, they are points.
ROUND_XY_TO_GRID	2	If set, round the xy values to grid; if not set do not round xy values to grid (relevant only to bit 1 is set)
WE_HAVE_A_SCALE	3	If set, there is a simple scale for the component. If not set, scale is 1.0.
(this bit is obsolete)	4	(obsolete; set to zero)
MORE_COMPONENTS	5	If set, at least one additional glyph follows this one.
WE_HAVE_AN_X_AND_Y_SCALE	6	If set the x direction will use a different scale than the y direction.
WE_HAVE_A_TWO_BY_TWO	7	If set there is a 2-by-2 transformation that will be used to scale the component.
WE_HAVE_INSTRUCTIONS	8	If set, instructions for the component character follow the last component.
USE_MY_METRICS	9	Use metrics from this component for the compound glyph.
OVERLAP_COMPOUND	10	If set, the components of this compound glyph overlap.
