ABSTRACT:
An apparatus, program product and method for rotating image data using a block-based approach, wherein for each of a plurality of blocks of image data that define an image, a translation vector is applied to the block to translate the block a desired angle of rotation about a rotation point, e.g., to translate an anchor position for the block from a source point to a destination point. In addition, the image data within the block is rotated according to the desired angle of rotation, such that when the rotated image data is stored at the destination point of the block, the image data within the block is effectively rotated to the desired position.
