All known Subclasses: com.xoetrope.batik.ext.awt.RadialGradientPaint, com.xoetrope.batik.ext.awt.LinearGradientPaint,
| MultipleGradientPaint | | abstract public class MultipleGradientPaint implements Paint(Code) | | 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.
