The filteringapproach rasterizes the image at normal display resolution, then smooths the image's edges with image-processing techniques that examine a pixel's neighbors to blend a new color. This is generally faster, but degrages the image more than super-sampling. This procedure is computationally similar to the Photoshop "smooth" function.
