 public interface BufferedImageOpThis interface describes single-input/single-output operations performed onBufferedImageobjects. It is implemented byAffineTransformOp,ConvolveOp,ColorConvertOp,RescaleOp, andLookupOp. These objects can be passed into aBufferedImageFilterto operate on aBufferedImagein 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.

Method Detail- 
filterBufferedImage filter(BufferedImage src, BufferedImage dest) Performs a single-input/single-output operation on aBufferedImage. 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, aBufferedImagewith an appropriateColorModelis created.An IllegalArgumentExceptionmay be thrown if the source and/or destination image is incompatible with the types of images $ allowed by the class implementing this filter.- Parameters:
- src- The- BufferedImageto be filtered
- dest- The- BufferedImagein which to store the results$
- Returns:
- The filtered BufferedImage.
- Throws:
- IllegalArgumentException- If the source and/or destination image is not compatible with the types of images allowed by the class implementing this filter.
 
 - 
getBounds2DRectangle2D getBounds2D(BufferedImage src) Returns the bounding box of the filtered destination image. AnIllegalArgumentExceptionmay be thrown if the source image is incompatible with the types of images allowed by the class implementing this filter.- Parameters:
- src- The- BufferedImageto be filtered
- Returns:
- The Rectangle2Drepresenting the destination image's bounding box.
 
 - 
createCompatibleDestImageBufferedImage createCompatibleDestImage(BufferedImage src, ColorModel destCM) Creates a zeroed destination image with the correct size and number of bands. AnIllegalArgumentExceptionmay be thrown if the source image is incompatible with the types of images allowed by the class implementing this filter.- Parameters:
- src- The- BufferedImageto be filtered
- destCM-- ColorModelof the destination. If null, the- ColorModelof the source is used.
- Returns:
- The zeroed destination image.
 
 - 
getPoint2DPoint2D getPoint2D(Point2D srcPt, Point2D dstPt) Returns the location of the corresponding destination point given a point in the source image. IfdstPtis specified, it is used to hold the return value.- Parameters:
- srcPt- the- Point2Dthat represents the point in the source image
- dstPt- The- Point2Din which to store the result
- Returns:
- The Point2Din the destination image that corresponds to the specified point in the source image.
 
 - 
getRenderingHintsRenderingHints getRenderingHints() Returns the rendering hints for this operation.- Returns:
- The RenderingHintsobject for thisBufferedImageOp. Returns null if no hints have been set.
