A method for filling a region inside a closed loop line of a pattern with pixel data having values identical to those of pixel data forming the loop line. One pixel datum of a pixel to be processed is extracted from the image memory, together with pixel data of its neighboring pixels by scanning the image memory at least one time. A logical operation is performed to decide whether or not a value of said one pixel datum should be changed to a value of the pixel datum identical to those of the pixel data forming the loop line. In the logical operation, values of the pixel data of the neighboring pixels are used in addition to the value of said one pixel datum. A result of the logical operation is stored in a related storage region of the image memory in place of said one pixel datum. |
