public interface BufferedImageOp
This interface describes single-input/single-output
operations performed on BufferedImage objects.
It is implemented by AffineTransformOp,
ConvolveOp, ColorConvertOp, RescaleOp,
and LookupOp. These objects can be passed into
a BufferedImageFilter to operate on a
BufferedImage in the
ImageProducer-ImageFilter-ImageConsumer paradigm.
Classes that implement this interface must specify whether or not they allow in-place filtering-- filter operations where the source object is equal to the destination object.
This interface cannot be used to describe more sophisticated operations such as those that take multiple sources. Note that this restriction also means that the values of the destination pixels prior to the operation are not used as input to the filter operation.

BufferedImage filter(BufferedImage src,
BufferedImage dest)
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.
src - The BufferedImage to be filtereddest - The BufferedImage in which to store the results$
BufferedImage.
IllegalArgumentException - If the source and/or destination
image is not compatible with the types of images allowed by the class
implementing this filter.Rectangle2D getBounds2D(BufferedImage src)
IllegalArgumentException may be thrown if the source
image is incompatible with the types of images allowed
by the class implementing this filter.
src - The BufferedImage to be filtered
Rectangle2D representing the destination
image's bounding box.
BufferedImage createCompatibleDestImage(BufferedImage src,
ColorModel destCM)
IllegalArgumentException may be thrown if the source
image is incompatible with the types of images allowed
by the class implementing this filter.
src - The BufferedImage to be filtereddestCM - ColorModel of the destination. If null,
the ColorModel of the source is used.
Point2D getPoint2D(Point2D srcPt,
Point2D dstPt)
dstPt is specified, it
is used to hold the return value.
srcPt - the Point2D that represents the point in
the source imagedstPt - The Point2D in which to store the result
Point2D in the destination image that
corresponds to the specified point in the source image.RenderingHints getRenderingHints()
RenderingHints object for this
BufferedImageOp. Returns
null if no hints have been set.
