Examples of java.awt.MultipleGradientPaint

java.awt.MultipleGradientPaint
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 {@code LinearGradientPaint} and {@code RadialGradientPaint}. @author Nicholas Talian, Vincent Hardy, Jim Graham, Jerry Evans @since 1.6
