Method Details
-
getType
public int getType()- Specified by:
getType
in classGlyphSubtable
- Returns:
- this subtable's type
-
isCompatible
Determine if a glyph subtable is compatible with this glyph subtable. Two glyph subtables are compatible if the both may appear in a single lookup table.- Overrides:
isCompatible
in classGlyphPositioningSubtable
- Parameters:
subtable
- a glyph subtable to determine compatibility- Returns:
- true if specified subtable is compatible with this glyph subtable, where by compatible is meant that they share the same lookup type
-
position
Perform glyph positioning at the current index, mutating the positioning state object as required. Only the context associated with the current index is processed.- Specified by:
position
in interfaceGlyphPositioning
- Overrides:
position
in classGlyphPositioningSubtable
- 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.
-
getPairValues
Obtain associated pair values.- Parameters:
ci
- coverage indexgi1
- first input glyph indexgi2
- second input glyph index- Returns:
- pair values or null if none applies
