Add two images or an image and a constant. Combine three SingleBand images to create a TripleBand image.
Typical use is to generate a gray-scale version of a color image.
Pass one band of a TripleBand image and discard the other two bands. Compare two images based on conditional tests, generating a bitmap result. Map image data into a specific integer range by either clipping or scaling. Convert intensity values into color-map indexes which store the mapped intensity values. Can be used to implement effects such as blurring, embossing and sharpening.
