Interface RasterOp
- AffineTransformOp, BandCombineOp, ColorConvertOp, ComponentDataBlitOp, ConvolveOp, LookupOp, RescaleOp
An operation that is performed on one raster (the source) producing a new
raster (the destination).
createCompatibleDestRaster
public WritableRaster createCompatibleDestRaster(Raster src)
Returns a raster that can be used by this RasterOp as the
destination raster when operating on the specified source raster.
- A new writable raster that can be used as the destination raster.
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
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).
src - the source raster.dest - the destination raster (null permitted).
getBounds2D
public Rectangle2D getBounds2D(Raster src)
Returns the bounds of the destination raster on the basis of this
RasterOp being applied to the specified source raster.
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.
srcPoint - the source point.destPoint - the destination point (null permitted).
