<p>It is an object to provide a figure drawing and processing device and a processing method that prevent painting out a common side of neighboring figures twice, so as to precisely draw a contour line of an arbitrary closed polygon. The figure drawing and processing device and the processing method are comprised of a means (2) that increases or decreases the number of pixels by one pixel up to the final painting-out pixel on a scanning line, a means (3) that increases the number of scanning lines for drawing by one, and a means (4) that outputs drawing pixel data under control of the means (1) and (3). The figure drawing and processing device and the processing method are further comprised of a stencil buffer (5) that holds intermediate stage figure data sequentially drawn, a means (6) that holds a plurality of sequential pixel data, a means (7) that detects a transit state of a data value in the means (6), and a means (8) that carries out an inversion/a non-inversion of a logical operation result of output data of the means (4) and data in the means (6) and reads it in a buffer (5).</p> |
