java.awt.image.BufferedImageOp.filter()

Performs a single-input/single-output operation on a BufferedImage. 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. @param src The BufferedImage to be filtered @param dest The BufferedImage in which to store the results$ @return The filtered BufferedImage. @throws IllegalArgumentException If the source and/or destinationimage is not compatible with the types of images allowed by the class implementing this filter.
