Class AWTEllipseRenderer

java.lang.Object
  jfig.objects.AWTEllipseRenderer

All Implemented Interfaces:

FigRenderer

public class AWTEllipseRenderer

extends java.lang.Object

implements FigRenderer

AWT 1.1 renderer for FIG circle and ellipse objects. In order to render as many FIG object attributes as possible, we don't call the AWT drawEllipse method, which also does not support rotated ellipses. Instead, we use a polyline approximation to the circle and ellipse, which allows us to at least suppport either thick (>1 pixel wide) line styles, or dash/dotted line style. As circles and ellipses are usually rare objects, this should not be a performance problem.
