Abstract: A method for rendering a visual representation of a font glyph, the method comprising computing a set of straight or curved lines, wherein the straight or curved lines correspond to edges of the font glyph, computing a grid of cells overlaying the straight or curved lines, and then rendering each pixel by generating an ellipse, computing a ray that intersects a centre of the ellipse, calculating a coverage value, and using the coverage value to calculate a colour value for each pixel.

Abstract: A method comprising computing a plurality of curved, wherein the curved lines correspond to a boundary of a graphical shape, computing buffers, and subdividing the curved lines to form a plurality of monotonic curved lines, computing a polygon for each curved line, wherein each polygon covers a line segment, calculating a signed distance for each pixel between the pixel and a point on the line segment extending across the relevant polygon that is closest to the pixel, reading from the buffer a stored signed distance for the relevant pixel and if the signed distance is less than the stored signed distance, writing the signed distance to the distance buffer, using the one or more signed distances to calculate one or more blending factors and using the one or more blending factors to blend the polygon thereby rendering the graphical shape.
