Constants

FLAG_ARGS_ARE_XY_VALUES

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_ARGS_ARE_XY_VALUES = 2

If this is set, the arguments are signed xy values; otherwise, they are unsigned point numbers.

FLAG_ARG_1_AND_2_ARE_WORDS

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_ARG_1_AND_2_ARE_WORDS = 1

If this is set, the arguments are 16-bit (uint16 or int16); otherwise, they are bytes (uint8 or int8).

FLAG_MORE_COMPONENTS

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_MORE_COMPONENTS = 32

Indicates at least one more glyph after this one.

FLAG_OVERLAP_COMPOUND

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_OVERLAP_COMPOUND = 1024

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

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_ROUND_XY_TO_GRID = 4

For the xy values if the preceding is true.

FLAG_SCALED_COMPONENT_OFFSET

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_SCALED_COMPONENT_OFFSET = 2048

The composite is designed to have the component offset scaled.

FLAG_UNSCALED_COMPONENT_OFFSET

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_UNSCALED_COMPONENT_OFFSET = 4096

The composite is designed not to have the component offset scaled.

FLAG_USE_MY_METRICS

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_USE_MY_METRICS = 512

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

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_WE_HAVE_AN_X_AND_Y_SCALE = 64

The x direction will use a different scale from the y direction.

FLAG_WE_HAVE_A_SCALE

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_WE_HAVE_A_SCALE = 8

This indicates that there is a simple scale for the component. Otherwise, scale = 1.0.

FLAG_WE_HAVE_A_TWO_BY_TWO

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_WE_HAVE_A_TWO_BY_TWO = 128

There is a 2 by 2 transformation that will be used to scale the component.

FLAG_WE_HAVE_INSTRUCTIONS

public const int SetaPDF_Core_Font_TrueType_Table_GlyphData_Description_Composite::FLAG_WE_HAVE_INSTRUCTIONS = 256

Following the last component are instructions for the composite character.
