gradient
Description
Convert a mono image to an RGB gradient image for better visibility. If the "insetinto" input has an image AND there is a valid ROI in the mono image, the image will be inset into the RGB of the insetinto image. NOTE: if you change the "insetinto" image's RGB mapping you may need to "run all" to see the the change reflected.
