RasterOp | public interface RasterOp (Code) | | 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.

Method Summary | |
public WritableRaster | createCompatibleDestRaster(Raster src) Creates a zeroed destination Raster with the correct size and number of
bands. | public WritableRaster | filter(Raster src, WritableRaster dest) Performs a single-input/single-output operation from a source Raster
to a destination Raster. | public Rectangle2D | getBounds2D(Raster src) Returns the bounding box of the filtered destination Raster. | public Point2D | getPoint2D(Point2D srcPt, Point2D dstPt) Returns the location of the destination point given a
point in the source Raster. | public RenderingHints | getRenderingHints() Returns the rendering hints for this RasterOp. |
createCompatibleDestRaster | public WritableRaster createCompatibleDestRaster(Raster src)(Code) | | 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.
Parameters: src - the source Raster a WritableRaster that is compatible with src |
filter | public WritableRaster filter(Raster src, WritableRaster dest)(Code) | | 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.
Parameters: src - the source Raster Parameters: dest - the destination WritableRaster a WritableRaster that represents the result ofthe filtering operation. |
getBounds2D | public Rectangle2D getBounds2D(Raster src)(Code) | | 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.
Parameters: src - the source Raster a Rectangle2D that is the bounding box of the Raster resulting from the filteringoperation. |
getPoint2D | public Point2D getPoint2D(Point2D srcPt, Point2D dstPt)(Code) | | 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.
Parameters: srcPt - the source Point2D Parameters: dstPt - the destination Point2D the location of the destination point. |
getRenderingHints | public RenderingHints getRenderingHints()(Code) | | Returns the rendering hints for this RasterOp. Returns
null if no hints have been set.
the RenderingHints object of thisRasterOp . |
