Interface java.awt.image.BufferedImageOp
- Implementing Classes:
- LookupOp, AffineTransformOp, ThresholdOp, RescaleOp, ColorConvertOp, ConvolveOp
- 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.

filter
public 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.
getDestBounds
public 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.
createCompatibleDestImage
public 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.
getDestPoint
public 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.
