Abstract: A method includes receiving instructions to render an image comprising content defined by a two-dimensional (2D) primitive; determining a portion of the 2D primitive covering a tile of multiple tiles of the image; generating an edge definition to represent an edge of the portion of the 2D primitive; and for each row of pixels within at least a portion of the tile containing the portion of the 2D primitive: identifying, based on the edge definition, a left-most pixel and right-most pixel in the row that intersect the edge; identifying, based on the left-most pixel and the right-most pixel, a set of first pixels in the row intersecting the edge; determining, for each first pixel in the set, a coverage weight indicating a proportion of the first pixel covered by the 2D primitive; and determining color information for the set of first pixels based on the associated coverage weights.
