- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class BandMergeDescriptor
- extends OperationDescriptorImpl
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.
