, RescaleOp
public interface BufferedImageOp
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.
Modifier and Type | Method | Description |
---|---|---|
BufferedImage |
createCompatibleDestImage |
Creates a zeroed destination image with the correct size and number of bands. |
BufferedImage |
filter |
Performs a single-input/single-output operation on a BufferedImage . |
Rectangle2D |
getBounds2D |
Returns the bounding box of the filtered destination image. |
Point2D |
getPoint2D |
Returns the location of the corresponding destination point given a point in the source image. |
RenderingHints |
getRenderingHints() |
Returns the rendering hints for this 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.
