GlyphDescription

public class GlyfCompositeDescript
extends GlyfDescript

Glyph description for composite glyphs. Composite glyphs are made up of one or more simple glyphs, usually with some sort of transformation applied to each. This class is based on code from Apache Batik a subproject of Apache XMLGraphics. see http://xmlgraphics.apache.org/batik/ for further details.

Method Detail

resolve

public void resolve()

Resolve all parts of an composite glyph.

Specified by:

resolve in interface GlyphDescription

Overrides:

resolve in class GlyfDescript

getEndPtOfContours

Parameters:

i - the given point

Returns:

the y coordinate value for the given point

isComposite
