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).

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
