Class GlyfTable

java.lang.Object
org.docx4j.fonts.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.

  • Method Details

    • 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.

    • isComposite

      public boolean isComposite​(int indexInOriginal) throws java.io.IOException
      Throws:
      java.io.IOException

    • retrieveComposedGlyphs

      public java.util.Set<java.lang.Integer> retrieveComposedGlyphs​(int indexInOriginal) throws java.io.IOException
      Reads a composite glyph at a given index and retrieves all the glyph indices of contingent composed glyphs.
      Parameters:
      indexInOriginal - the glyph index of the composite glyph
      Returns:
      the set of glyph indices this glyph composes
      Throws:
      java.io.IOException - an I/O error
