public 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.

dest - the destination WritableRaster
Returns:
a WritableRaster that represents the result of the filtering operation.
