Abstract
A method includes logically organizing rasterized image data into a first matrix of pixel tiles and individually rotating each pixel tile so as to generate a corresponding pixel tile of a second matrix representing an orthogonal representation of the first matrix. Each pixel tile represents a set of buffer lines of a frame buffer storing rasterized image data. The pixel tile is rotated by accessing and storing each buffer line of pixel data in a set of tile buffers such that the pixel data for each pixel in the same column position of an adjacent row is stored in a different tile buffer so that the set of tile buffers can be individually accessed to obtain pixel data for a set of pixels in the same column position in adjacent rows. This obtained pixel data is written to a second frame buffer as a row of pixel data for the corresponding pixel tile of the second matrix.
