Abstract:
1. A computer-implemented method for determining fill styles for pixels in a scan line, the scan line comprising a first pixel having at least one edge, a second pixel without any edges, a third pixel having at least one edge, and a fourth pixel without any edges, the first, the second, the third, and the fourth pixels comprising being along a scan direction of the scan line, the method comprising: for each edge in the first pixel: for each edge that touches the bottom border of the first pixel, incrementing a first fill style parameter by a difference between a right fill style and a left fill style of the edge, wherein the leftmost fill style in the scan line is set to null; incrementing a second fill style parameter by the first fill style parameter of the first pixel; filling the second pixel with a first fill style equal to the second fill style parameter; for each edge in the third pixel, incrementing the second fill style parameter by the third fill style parameter of the third pixel; filling the fourth pixel with a second fill style equal to the second fill style parameter; and displaying the second and the fourth pixels on a display device to a user.
