- All Implemented Interfaces:
    org.apache.batik.bridge.TextPainter

      public class PSTextPainter
      extends NativeTextPainter

  Renders the attributed character iterator of a `TextNode`. This class draws the text directly using PostScript text operators so the text is not drawn using shapes which makes the PS files larger.

  The text runs are split into smaller text runs that can be bundles in single calls of the xshow, yshow or xyshow operators. For outline text, the charpath operator is used.
