| java.awt.image.BufferedImageOp
All known Subclasses: java.awt.image.RescaleOp, java.awt.image.ConvolveOp, java.awt.image.AffineTransformOp, java.awt.image.LookupOp,
| BufferedImageOp | | public interface BufferedImageOp (Code) | | This interface describes single-input/single-output
operations performed on 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.

| createCompatibleDestImage | | public BufferedImage createCompatibleDestImage(BufferedImage src, ColorModel destCM)(Code) | | Creates a zeroed destination image with the correct size and number of
bands.
An IllegalArgumentException may be thrown if the source
image is incompatible with the types of images allowed
by the class implementing this filter.
Parameters:
src - The BufferedImage to be filtered
Parameters:
destCM - ColorModel of the destination. If null,the ColorModel of the source is used. The zeroed destination image. |
| filter | | public BufferedImage filter(BufferedImage src, BufferedImage dest)(Code) | | Performs 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 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.
Parameters:
src - The BufferedImage to be filtered
Parameters:
dest - The BufferedImage in which to store the results$ The filtered BufferedImage.
throws:
IllegalArgumentException - If the source and/or destinationimage is not compatible with the types of images allowed by the classimplementing this filter. |
| getBounds2D | | public Rectangle2D getBounds2D(BufferedImage src)(Code) | | Returns the bounding box of the filtered destination image.
An IllegalArgumentException may be thrown if the source
image is incompatible with the types of images allowed
by the class implementing this filter.
Parameters:
src - The BufferedImage to be filtered The Rectangle2D representing the destinationimage's bounding box. |
| getPoint2D | | public Point2D getPoint2D(Point2D srcPt, Point2D dstPt)(Code) | | Returns the location of the corresponding destination point given a
point in the source image. If dstPt is specified, it
is used to hold the return value.
Parameters:
srcPt - the Point2D that represents the point inthe source image
Parameters:
dstPt - The Point2D in which to store the result The Point2D in the destination image thatcorresponds to the specified point in the source image. |
| getRenderingHints | | public RenderingHints getRenderingHints()(Code) | | Returns the rendering hints for this operation.
The RenderingHints object for thisBufferedImageOp. Returnsnull if no hints have been set. |
