Abstract

An apparatus, method, system, and article of manufacture provide the ability to process image data in a computer system. A user-operable representation of at least one image-processing function is configured with an adjustable opacity. The user-operable representation is created and processed as a three-dimensional object. The opacity of the representation is adjusted in response to user input. The representation is ten blended with image data to generate blended image data that is output to a display.
