Summary
Constants
FLAG_ARGS_ARE_XY_VALUES
If this is set, the arguments are signed xy values; otherwise, they are unsigned point numbers.
FLAG_ARG_1_AND_2_ARE_WORDS
If this is set, the arguments are 16-bit (uint16 or int16); otherwise, they are bytes (uint8 or int8).
FLAG_MORE_COMPONENTS
Indicates at least one more glyph after this one.
FLAG_OVERLAP_COMPOUND
If set, the components of the compound glyph overlap. Use of this flag is not required in OpenType— that is, it is valid to have components overlap without having this flag set. It may affect behaviors in some platforms, however.
FLAG_ROUND_XY_TO_GRID
For the xy values if the preceding is true.
FLAG_SCALED_COMPONENT_OFFSET
The composite is designed to have the component offset scaled.
FLAG_UNSCALED_COMPONENT_OFFSET
The composite is designed not to have the component offset scaled.
FLAG_USE_MY_METRICS
If set, this forces the aw and lsb (and rsb) for the composite to be equal to those from this original glyph. This works for hinted and unhinted characters.
FLAG_WE_HAVE_AN_X_AND_Y_SCALE
The x direction will use a different scale from the y direction.
FLAG_WE_HAVE_A_SCALE
This indicates that there is a simple scale for the component. Otherwise, scale = 1.0.
FLAG_WE_HAVE_A_TWO_BY_TWO
There is a 2 by 2 transformation that will be used to scale the component.
FLAG_WE_HAVE_INSTRUCTIONS
Following the last component are instructions for the composite character.
Properties
$_length
The glyph description length
