Class BandCombineOp
- RasterOp
Filter Raster pixels by applying a matrix.
BandCombineOp applies a matrix to each pixel to produce new pixel values.
The width of the matrix must be the same or one more than the number of
bands in the source Raster. If one more, the pixels in the source are
assumed to contain an implicit 1.0 at the end.
The rows of the matrix are multiplied by the pixel to produce the values
for the destination. Therefore the destination Raster must contain the
same number of bands as the number of rows in the filter matrix.
This Op assumes that samples are integers; floating point sample types will
be rounded to their nearest integer value during filtering.

filter
public WritableRaster filter(Raster src,
WritableRaster dest)
Filter Raster pixels through a matrix. Applies the Op matrix to source
pixes to produce dest pixels. Each row of the matrix is multiplied by the
src pixel components to produce the dest pixel. If matrix is one more than
the number of bands in the src, the last element is implicitly multiplied
by 1, i.e. added to the sum for that dest component. If dest is null, a
suitable Raster is created. This implementation uses
createCompatibleDestRaster.
