org.apache.flex.forks.batik.gvt.text.TextSpanLayout
Class that performs layout of attributed text strings into glyph sets paintable by TextPainter instances. Similar to java.awt.font.TextLayout in function and purpose. Note that while this utility interface is provided for the convenience of TextPainter implementations, conforming TextPainters are not required to use this class. @see java.awt.font.TextLayout @see org.apache.flex.forks.batik.gvt.TextPainter @author Bill Haneman @version $Id: TextSpanLayout.java,v 1.18 2005/03/27 08:58:35 cam Exp $
