0N/A * This interface describes single-input/single-output
0N/A * operations performed on Raster objects. It is implemented by such
0N/A * classes as AffineTransformOp, ConvolveOp, and LookupOp. The Source
0N/A * and Destination objects must contain the appropriate number
0N/A * of bands for the particular classes implementing this interface.
0N/A * Otherwise, an exception is thrown. This interface cannot be used to
0N/A * describe more sophisticated Ops such as ones that take multiple sources.
0N/A * Each class implementing this interface will specify whether or not it
0N/A * will allow an in-place filtering operation (i.e. source object equal
0N/A * to the destination object). Note that the restriction to single-input
0N/A * operations means that the values of destination pixels prior to the
0N/A * operation are not used as input to the filter operation.
