The present system provides circuitry to enable pixel signals, which represent information that is stored in a first section of memory (and which information defines an image, or images to be viewed on a CRT display) to be transferred to a different section of memory and in the course of the transferral be: expanded or reduced in number; and/or rotated, by arbitrary angles from the original orientation of the image; and/or have the holes, i.e. missing pixels, which occur because of the rotation by the arbitrary angles, filled in. |
