Abstract
A graphic rendering apparatus includes a processing unit and a storage unit. The storage unit is stored with a piece of information. The piece of information defines a virtual area on a display. A pixel of the display overlaps a part of the virtual area, and the part corresponds to a color. The pixel defines a first boundary, a second boundary, a third boundary, and a fourth boundary. The processing unit decides a first coverage rate, a second coverage rate, a third coverage rate, and a fourth coverage rate of the virtual area on the first boundary, the second boundary, the third boundary, and the fourth boundary, respectively. The processing unit decides a display color of the pixel with reference to the color and the first coverage rate, the second coverage rate, the third coverage rate, and the fourth coverage rate.
