java.lang.Object
  org.extex.font.format.xtf.tables.TtfTableCMAP.Format
      org.extex.font.format.xtf.tables.TtfTableCMAP.Format6

All Implemented Interfaces:

XMLWriterConvertible

Enclosing class:

TtfTableCMAP

public class TtfTableCMAP.Format6
extends TtfTableCMAP.Format

Format 6 is used to map 16-bit, 2-byte, characters to glyph indexes. It is sometimes called the trimmed table mapping. It should be used when character codes for a font fall into a single contiguous range. This results in what is termed adense mapping. Two-byte fonts that are not densely mapped (due to their multiple contiguous ranges) should use Format 4.

Type	Name	Description
USHORT	format	Format number is set to 6.
USHORT	length	Length in bytes.
USHORT	version	Version number (starts at 0)
USHORT	firstCode	First character code of subrange.
USHORT	entryCount	Number of character codes in subrange.
USHORT	glyphIdArray [entryCount]	Array of glyph index values for character codes in the range.

Method Summary
