Interface BufferedImageOp

Known Implementing Classes:
AffineTransformOp, ColorConvertOp, ConvolveOp, LookupOp, RescaleOp

public interface BufferedImageOp

An operation that is performed on one BufferedImage (the source) producing a new BufferedImage (the destination).

Method Summary

BufferedImage
createCompatibleDestImage(BufferedImage src, ColorModel dstCM)
Returns a new BufferedImage that can be used by this BufferedImageOp as the destination image when filtering the specified source image.
BufferedImage
filter(BufferedImage src, BufferedImage dst)
Performs an operation on the source image, returning the result in a BufferedImage.
Rectangle2D
getBounds2D(BufferedImage src)
Returns the bounds of the destination image on the basis of this BufferedImageOp being applied to the specified source image.
Point2D
getPoint2D(Point2D src, Point2D dst)
Returns the point on the destination image that corresponds to the given point on the source image.
RenderingHints
getRenderingHints()
Returns the rendering hints for this operation.

Method Details

createCompatibleDestImage

public BufferedImage createCompatibleDestImage(BufferedImage src,
                                               ColorModel dstCM)
Returns a new BufferedImage that can be used by this BufferedImageOp as the destination image when filtering the specified source image.
Parameters:
src - the source image.
dstCM - the color model for the destination image.
Returns:
A new image that can be used as the destination image.

filter

public BufferedImage filter(BufferedImage src,
                            BufferedImage dst)
Performs an operation on the source image, returning the result in a BufferedImage. If dest is null, a new BufferedImage will be created by calling the createCompatibleDestImage(BufferedImage,ColorModel) method. If dest is not null, the result is written to dest then returned (this avoids creating a new BufferedImage each time this method is called).
Parameters:
src - the source image.
dst - the destination image (null permitted).
Returns:
The filterd image.

getBounds2D

public Rectangle2D getBounds2D(BufferedImage src)
Returns the bounds of the destination image on the basis of this BufferedImageOp being applied to the specified source image.
Parameters:
src - the source image.
Returns:
The destination bounds.

getPoint2D

public Point2D getPoint2D(Point2D src,
                          Point2D dst)
Returns the point on the destination image that corresponds to the given point on the source image.
Parameters:
src - the source point.
dst - the destination point (null permitted).
Returns:
The destination point.

getRenderingHints

public RenderingHints getRenderingHints()
Returns the rendering hints for this operation.
Returns:
The rendering hints.
