Class SVGGC

java.lang.Object
  org.eclipse.tptp.platform.report.igc.svg.internal.SVGGC

All Implemented Interfaces:

IGC

public class SVGGC

extends java.lang.Object

implements IGC

Test for SVG implementation on IGC.... Special feature added on SVG: - fillRect(int,int,int,int) and fillRect(Rect) support GradientBrush. Note: SVG use clockwise angle whereas IGC uses counter-clockwise angle !.
