Class TtfTablePOST

java.lang.Object
  org.extex.font.format.xtf.tables.AbstractXtfTable
      org.extex.font.format.xtf.tables.TtfTablePOST

All Implemented Interfaces:

XtfGlyphName, XtfTable, XMLWriterConvertible

public class TtfTablePOST
extends AbstractXtfTable
implements XtfTable, XMLWriterConvertible

The 'post' table contains information needed to use a TrueType font on a PostScript printer. It contains the data needed for the FontInfo dictionary entry as well as the PostScript names for all of the glyphs in the font. It also contains memory usage information needed by the PostScript driver for memory management.

Type	Name	Description
Fixed	Format Type	0x00010000 for format 1.0, 0x00020000 for format 2.0, and so on
Fixed	italicAngle	Italic angle in counter-clockwise degrees from the vertical. Zero for upright text, negative for text that leans to the right (forward)
FWord	underlinePosition	Suggested values for the underline position (negative values indicate below baseline).
FWord	underlineThickness	Suggested values for the underline thickness.
ULONG	isFixedPitch	Set to 0 if the font is proportionally spaced, non-zero if the font is not proportionally spaced (i.e. monospaced).
ULONG	minMemType42	Minimum memory usage when a TrueType font is downloaded.
ULONG	maxMemType42	Maximum memory usage when a TrueType font is downloaded.
ULONG	minMemType1	Minimum memory usage when a TrueType font is downloaded as a Type 1 font.
ULONG	maxMemType1	Maximum memory usage when a TrueType font is downloaded as a Type 1 font.

Format 2

Type	Name	Description
uint16	numberOfGlyphs	number of glyphs
uint16	glyphNameIndex[numberOfGlyphs]	Ordinal number of this glyph in 'post' string tables. This is not an offset.
Pascal string	names[numberNewGlyphs]	glyph names with length bytes [variable] (a Pascal string)

Format 3

This version is used by OpenType fonts with TrueType or CFF data. The version makes it possible to create a special font that is not burdened with a large 'post' table set of glyph names.

This version specifies that no PostScript name information is provided for the glyphs in this font file. The printing behavior of this version on PostScript printers is unspecified, except that it should not result in a fatal or unrecoverable error. Some drivers may print nothing, other drivers may attempt to print using a default naming scheme.
