ABSTRACT:
An image processing apparatus for drawing the inside of an image area which is expressed by vector data has reversal and painting means for sequentially reversing write dots (data) along the storage direction in correspondence to one outline which is specified by vector data, for writing the reversed write dots into an image memory, and for painting the inside of an image area like a closed figure in the image memory. Thus, the area in a closed figure can be painted at a high speed using an apparatus which has a simple construction. The optimum reversal and painting method can be selectively switched in accordance with the attribute data of an image area to be painted, so that the optimum. painting process can be executed at a high precision and at a high speed.
