filter
public WritableRaster filter(Raster src,
WritableRaster dest) Performs an operation on the source raster, returning the result in a
writable raster. If
dest is
null, a new
WritableRaster will be created by calling the
RasterOp.createCompatibleDestRaster(Raster) method. If
dest
is not
null, the result is written to
dest then
returned (this avoids creating a new
WritableRaster each
time this method is called).
- filter in interface RasterOp
src - the source raster.dest - the destination raster (null permitted).
getPoint2D
public Point2D getPoint2D(Point2D srcPoint,
Point2D destPoint) Returns the point on the destination raster that corresponds to the given
point on the source raster.
- getPoint2D in interface RasterOp
srcPoint - the source point.destPoint - the destination point (null permitted).
