javax.media.jai.operator .BandMergeDescriptor

BandMergeDescriptor

public class BandMergeDescriptor extends OperationDescriptorImpl (Code)

An OperationDescriptor describing the "BandMerge" operation.

The BandMerge operation takes two or more rendered or renderable images, and performs "BandMerge" on every pixel. Each source image should be non-null. The number of bands of the destination image is the sum of those of all source images.

Intuitively, "BandMerge" stacks all the bands of source images in the order given in a ParameterBlock. If image1 has three bands and image2 has one band, the bandmerged image has 4 bands. Three grayscale images can be used to merge into an RGB image in this way. The destination image bound is the intersection of the source image bounds. If the sources don't intersect, the destination will have a width and height of 0.
