Interface java.awt.image.RasterOp
- All Known Implementing Classes:
- LookupOp, RescaleOp, ColorConvertOp, BandCombineOp, ConvolveOp, AffineTransformOp
- public abstract interface RasterOp
This interface describes single-input/single-output
operations performed on Raster objects. It is implemented by such
classes as AffineTransformOp, ConvolveOp, and LookupOp. The Source
and Destination objects must contain the appropriate number
of bands for the particular classes implementing this interface.
Otherwise, an exception is thrown. 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 WritableRaster filter(Raster src,
WritableRaster dest)
- Performs a single-input/single-output operation from a source Raster
to a destination Raster. If the destination Raster is null, a
new Raster will be created. The IllegalArgumentException may be thrown
if the source and/or destination Raster is incompatible with the types
of Rasters allowed by the class implementing this filter.
getBounds2D
public Rectangle2D getBounds2D(Raster src)
- Returns the bounding box of the filtered destination Raster.
The IllegalArgumentException may be thrown if the source Raster
is incompatible with the types of Rasters allowed
by the class implementing this filter.
createCompatibleDestRaster
public WritableRaster createCompatibleDestRaster(Raster src)
- Creates a zeroed destination Raster with the correct size and number of
bands.
The IllegalArgumentException may be thrown if the source Raster
is incompatible with the types of Rasters allowed
by the class implementing this filter.
getPoint2D
public Point2D getPoint2D(Point2D srcPt,
Point2D dstPt)
- Returns the location of the destination point given a
point in the source Raster. If dstPt is non-null, it
will be used to hold the return value.
getRenderingHints
public RenderingHints getRenderingHints()
- Returns the rendering hints for this RasterOp. Returns
null if no hints have been set.
