public interface GlyphSubstitution

The GlyphSubstitution interface is implemented by a glyph substitution subtable that supports the determination of glyph substitution information based on script and language of the corresponding character content.

  • Method Details

    • substitute

      boolean substitute(GlyphSubstitutionState ss)
      Perform glyph substitution at the current index, mutating the substitution state object as required. Only the context associated with the current index is processed.
      Parameters:
      ss - glyph substitution state object
      Returns:
      true if the glyph subtable was applied, meaning that the current context matches the associated input context glyph coverage table
