This interface defines the set of calls that pipeline objects can use to pass on responsibility for performing various image copy commands. There are 3 types of image copies handled by this class: - copyImage: These methods simply copy the pixels from the src to dest, either from (0, 0) (implicit) or from a given (sx, sy) location. - scaleImage: These methods copy from src to dest while scaling the source image. The src and dest rectangles are used to specify the scale. - copyImageBg: These methods behave the same as the copyImage methods except they substitute the given background color for any transparent pixels. - scaleImageBg: These methods behave the same as the scaleImage methods except they substitute the given background color for any transparent pixels. - transformImage....
