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.This work was originally authored by Glenn Adams (gadams@apache.org).

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
