Abstract
Methods and systems are provided for producing a rotated textured tile on a display device. An unrotated textured tile is identified. A supertile that contains repeated adjacent copies of at least part of the unrotated tile is produced. The supertile is rotated through an arbitrary angle. A period in X and a period in Y are selected. To select a period, a pixel-wide window is moved along the axis, and pixels in the window are measured against pixels in a reference location until a match of acceptable accuracy is found. If no match is found then one or more parameters are perturbed and the sliding-comparison process repeats.
