If there is one more column in the matrix than the number of bands, there is an implied 1 at the end of the vector of band samples representing a pixel. The height of the matrix must be equal to the number of bands in the destination. <p> For example, a 3-banded <CODE>Raster</CODE> might have the following transformation applied to each pixel in order to invert the second band of the <CODE>Raster</CODE>. <pre> [ 1.0 0.0 0.0 0.0 ] [ b1 ] [ 0.0 -1.0 0.0 255.0 ] x [ b2 ] [ 0.0 0.0 1.0 0.0 ] [ b3 ] [ 1 ] </pre> <p> Note that the source and destination
