An apparatus, program product and method for rotating image data using a block-based approach, wherein for each of a plurality of blocks (122) of image data that define an image (120), a translation vector is applied to the block (122) to translate the block (122) a desired angle of rotation about a rotation point, e.g., to translate an anchor position for the block (122) from a source point to a destination point. In addition, the image data within the block (122) 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 (122) is effectively rotated to the desired position. |
