Method and system for forming a rotated image on an imaging element using limited system resources

摘要

The present invention is a method and system for forming a rotated image on an imaging element without requiring vast amounts of physical memory, virtual memory or specialized hardware. Furthermore, the system and technique is efficient and inexpensive to implement. The present invention effects efficient image rotation by decomposing the image into an array of data blocks defined by a plurality of data block columns and a plurality of data block rows. The present invention independently rotates each data block and writes the rotated data block to a temporary image file starting at a corresponding calculated position. The starting position is such that during a post-processing phase a plurality of rotated data blocks are retrieved and easily processed to form at least one complete scan line of pixels. Finally, the imaging element is sequentially exposed by a radiation source to form each scan line on the imaging element, thereby forming a rotated image on the imaging element.
