Abstract
A system and method for rotating a source image by a first non-zero angle is provided. The method includes: defining a template for the source image, the template representing a rotation of the source image about an axis of the source image by second angle, where the second angle is the negative of the first non-zero angle; determining overlap between the template and the source image; separating the template into a plurality of strips covering at least the area of overlap; and for each strip: indentifying an initial pixel in the source image within the strip and storing the image data of the initial pixel; storing the image data of all remaining pixels within both the strip and the overlap in a database format in which the all remaining pixels is defined by a Y and X offset from the initial pixel.
