1. A method for the detection of antialiased pixels within rasterized image data, comprising the steps of: storing, in a scanline buffer memory, a predefined number of scanlines of data including data for a target pixel position; storing, in a tag buffer memory, a plurality of binary antialiasing tags, including at least a previously estimated tag for the target pixel position; and generating, as a function of the pixel data for the target pixel and subsequent neighboring pixels and the previously estimated tag for the target pixel position, an antialiasing tag for the target pixel position.
