ABSTRACT:
Upscaling of an anti-aliased graphical element in a raster image includes generating a grid of pixels. Resolution of the grid is higher than resolution of the graphical element. Each pixel in the anti-aliased graphical element corresponds to a group of pixels in the higher resolution grid. The upscaling further includes distributing coverage of each transition pixel in the anti-aliased graphical element to the corresponding pixels in the higher resolution grid. The coverage is distributed unevenly.
