Class GlyfTable

java.lang.Object
  org.apache.fop.fonts.truetype.GlyfTable

public class GlyfTable
extends java.lang.Object

This "glyf" table in a TrueType font file contains information that describes the glyphs. This class is responsible for creating a subset of the "glyf" table given a set of glyph indices.

Field Summary

protected java.util.Set<java.lang.Integer>	composedGlyphs All the glyphs that are composed, but do not appear in the subset.
protected java.util.Map<java.lang.Integer,java.lang.Integer>	subset

Constructor Summary

protected

GlyfTable(FontFileReader in, OFMtxEntry[] metrics, OFDirTabEntry dirTableEntry, java.util.Map<java.lang.Integer,java.lang.Integer> glyphs)

Method Summary

protected void	addAllComposedGlyphsToSubset() Adds to the subset, all the glyphs that are composed by a glyph, but do not appear themselves in the subset.
protected void	populateGlyphsWithComposites() Populates the map of subset glyphs with all the glyphs that compose the glyphs in the subset.

Constructor Detail

GlyfTable

protected GlyfTable(FontFileReader in,
                    OFMtxEntry[] metrics,
                    OFDirTabEntry dirTableEntry,
                    java.util.Map<java.lang.Integer,java.lang.Integer> glyphs)
             throws java.io.IOException

Throws:

java.io.IOException

Method Detail

populateGlyphsWithComposites

protected void populateGlyphsWithComposites()
                                     throws java.io.IOException

Populates the map of subset glyphs with all the glyphs that compose the glyphs in the subset. This also re-maps the indices of composed glyphs to their new index in the subset font.

Throws:

java.io.IOException - an I/O error

addAllComposedGlyphsToSubset

protected void addAllComposedGlyphsToSubset()

Adds to the subset, all the glyphs that are composed by a glyph, but do not appear themselves in the subset.
