Class TtfTableLOCA

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

All Implemented Interfaces:

XtfGlyphName, XtfTable, XMLWriterConvertible

public class TtfTableLOCA
extends AbstractXtfTable
implements XtfTable, XMLWriterConvertible

The 'loca' table stores the offsets to the locations of the glyphs in the font relative to the beginning of the 'glyf' table. Its purpose is to provide quick access to the data for a particular character.

Glyph Index	Offset	Glyph length
0	0	100
1	100	150
2	250
	..	..	..
n-1	1170	120
extra	1290

'loca' short version

Type	Name	Description
uint16	offsets[n]	The actual local offset divided by 2 is stored. The value of n is the number of glyphs in the font + 1. The number of glyphs in the font is found in the maximum profile table.

'loca' long version

Type	Name	Description
uint32	offsets[n]	The actual local offset is stored. The value of n is the number of glyphs in the font + 1. The number of glyphs in the font is found in the maximum profile table.
