java.lang.Object java.awt.image.ImageFilter java.awt.image.BufferedImageFilter
public class BufferedImageFilter
The BufferedImageFilter
class subclasses an
ImageFilter
to provide a simple means of
using a single-source/single-destination image operator
(BufferedImageOp
) to filter a BufferedImage
in the Image Producer/Consumer/Observer
paradigm. Examples of these image operators are: ConvolveOp
,
AffineTransformOp
and LookupOp
.

being filtered. Developers using this class to retrieve pixels from
an image should avoid calling this method directly since that
operation could result in problems with retrieving the requested
pixels.
