Examples of java.awt.image.LookupOp.filter()

java.awt.image.LookupOp.filter()
Performs a lookup operation on a BufferedImage. If the color model in the source image is not the same as that in the destination image, the pixels will be converted in the destination. If the destination image is null, a BufferedImage will be created with an appropriate ColorModel. An IllegalArgumentException might be thrown if the number of arrays in the LookupTable does not meet the restrictions stated in the class comment above, or if the source image has an IndexColorModel. @param src the BufferedImage to be filtered @param dst the BufferedImage in which to store the results of the filter operation @return the filtered BufferedImage. @throws IllegalArgumentException if the number of arrays in theLookupTable does not meet the restrictions described in the class comments, or if the source image has an IndexColorModel.
