public abstract BufferedImage filter(BufferedImage src,
BufferedImage dest)
java.awt.image.BufferedImageOpBufferedImage.
If the color models for the two images do not match, a color
conversion into the destination color model is performed.
If the destination image is null,
a BufferedImage with an appropriate ColorModel
is created.
An IllegalArgumentException may be thrown if the source
and/or destination image is incompatible with the types of images $
allowed by the class implementing this filter.
