public void compose(java.awt.image.Raster src, java.awt.image.Raster dstIn, java.awt.image.WritableRaster dstOut)
Composes the two source {@link Raster} objects and places 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(java.awt.image.ColorModel, java.awt.image.ColorModel, 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
