Method Detail

position
boolean position(GlyphPositioningState ps)
Perform glyph positioning at the current index, mutating the positioning state object as required. Only the context associated with the current index is processed.- Parameters:
ps
- glyph positioning state object- Returns:
- true if the glyph subtable applies, meaning that the current context matches the associated input context glyph coverage table; note that returning true does not mean any position adjustment occurred; it only means that no further glyph subtables for the current lookup table should be applied.
