ABSTRACT:
A system for generating and applying alpha values is discussed. Different sets of alpha values are generated and stored for each color component of a set of image data associated with a foreground object. A graphics-processing engine processes the foreground object with respect to a background object to be displayed in the same location. Red components of the foreground object are blended with red components of the background object using red-specific alpha values. Blue components of the foreground object are blended with blue components of the background object using blue-specific alpha values and green components of the foreground object are blended with green components of the background object using green-specific alpha values.
