Abstract
A processor unit that can be used in a handheld device and configured for anti-aliasing of a vector graphics image, and including a counter value calculator configured to calculate, for one edge at a time and pixel-by-pixel, counter values for each pixel in a rasterization direction, a counter value recorder configured to store the calculated counter values in an edge buffer, and a pixel coverage value calculator configured to calculate pixel coverage values based on the stored counter values. The calculated pixel coverage values can be utilized for anti-aliasing the vector graphics image, while rasterizing the vector graphics image.
