ABSTRACT OF THE DISCLOSURE A method for rotating an image by 90 degrees includes the steps of: storing the image in a raster format arranged in r rows by c columns, im- age information in each row being stored in a num- ber of bytes, each byte having b bits, there being c/b bytes in each row of the raster format; moving a block of the image into a temporary storage, there being n rows by m columns in the block; sep- arating each image block into groups of bytes of rotatable size; determining for each group if all bits are the same value; rotating each group that does not have all bits the same value; storing each rotated group in an output area of the raster storage; repeating the above steps for all remain- ing blocks of the image.
