Examples of ae.java.awt.CompositeContext.compose()

ae.java.awt.CompositeContext.compose()

Composes the two source {@link Raster} objects andplaces the result in the destination {@link WritableRaster}. Note that the destination can be the same object as either the first or second source. Note that dstIn and dstOut must be compatible with the dstColorModel passed to the {@link Composite#createContext(ae.java.awt.image.ColorModel,ae.java.awt.image.ColorModel,ae.java.awt.RenderingHints) createContext}method of the Composite interface. @param src the first source for the compositing operation @param dstIn the second source for the compositing operation @param dstOut the WritableRaster into which theresult of the operation is stored @see Composite
