Abstract
Rotation in the storage domain is a one-one function with the domain equal to the range. This permits an image to be rotated in place. Each image size implies at least one garland of closed chains of tiles. Each image includes a spanning set of these garlands. Rotation in place moves each pixel to the next location on its garland. On completion of a garland by return to the initial tile, tiles on the next garland are moved. Image rotation is complete after all the garlands have been traversed. This invention first linearized the two-dimensional tiles sliding into groups of super-pixels at contiguous locations above the image buffer. The tiles are rotated in place. The shuffled tiles are delinearized into rectangular blocks and then re-pitched if needed.
