Class SVGMultipleGradientPaint

  • All Implemented Interfaces:
    java.awt.Paint, java.awt.Transparency
    Direct Known Subclasses:
    SVGRadialGradientPaint
    public abstract class SVGMultipleGradientPaint
extends java.lang.Object
implements java.awt.Paint
    This is the superclass for Paints which use a multiple color gradient to fill in their raster. It provides storage for variables and enumerated values common to LinearGradientPaint and RadialGradientPaint.
    Since:
    1.6
