Interface java.awt.image.BufferedImageOp

public interface BufferedImageOp
This is an interface that describes single-input/single-output operations performed on BufferedImage objects. This is implemented by such classes as AffineTransformOp, ConvolveOp, BandCombineOp, and LookupOp. These objects can be passed into a BufferedImageFilter to operate on a BufferedImage in the ImageProducer-ImageFilter-ImageConsumer paradigm. This interface cannot be used to describe more sophisticated Ops such as ones that take multiple sources. Each class implementing this interface will specify whether or not it will allow an in-place filtering operation (i.e. source object equal to the destination object). Note that the restriction to single-input operations means that the values of destination pixels prior to the operation are not used as input to the filter operation.

Method Index

o createCompatibleDestImage(BufferedImage, ColorModel)
Creates an empty destination image with the correct size and number of components.
o filter(BufferedImage, BufferedImage)
Perform a single-input/single-output operation on a BufferedImage.
o getDestBounds(BufferedImage)
Returns the bounding box of the filtered destination image.
o getDestPoint(Point2D, Point2D)
Returns the location of the destination point given a point in the source image.

Methods

o filter 
public abstract BufferedImage filter(BufferedImage src,
                                     BufferedImage dest)
Perform 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 will be performed. If the destination image is null, a BufferedImage with an appropriate ColorModel will be created. The IllegalArgumentException may be thrown if the source and/or destination image is incompatible with the types of images allowed by the subclass implementing this filter.

o getDestBounds 
public abstract Rectangle2D getDestBounds(BufferedImage src)
Returns the bounding box of the filtered destination image. The IllegalArgumentException may be thrown if the source image is incompatible with the types of images allowed by the subclass implementing this filter.

o createCompatibleDestImage 
public abstract BufferedImage createCompatibleDestImage(BufferedImage src,
                                                        ColorModel destCM)
Creates an empty destination image with the correct size and number of components. The IllegalArgumentException may be thrown if the source image is incompatible with the types of images allowed by the subclass implementing this filter.

Parameters:
src - Source image for the filter operation
destCM - ColorModel of the destination. If null, the ColorModel of the source will be used.
o getDestPoint 
public abstract Point2D getDestPoint(Point2D srcPt,
                                     Point2D dstPt)
Returns the location of the destination point given a point in the source image. If dstPt is non-null, it will be used to hold the return value.
