What is disclosed is a novel system and method for performing spatial gamut mapping on a received input color image having a plurality of pixels. The structure includes a substrate having first and second surfaces. Replies associated with commands originating from a first processor are buffered by the RAID controller in a first reply queue, and replies associated with commands originating from a second processor are buffered in a second reply queue. The bushing includes a proximal axis of alignment in alignment with the central position of the tray and a distal axis of alignment that is co-linear to the longitudinal axis of the stem. The device is made up of a button elastically supported by the lever in such a way as to be able to provide, with the lever in the maximum opening position, a locking engagement between the lever and the external casing. The fixing pieces are disposed on the sides of the frame and make the frame easily attachable and detachable.
