Abstract
A method of determining a coverage area of a pixel covered by a scalable path definition for a character, is disclosed. An edge direction for each edge of the scalable path definition intersecting the pixel is received. A fragment area is determined for each of the intersecting edges, each of the fragment areas representing an area of the pixel located to a side of a corresponding edge. The side of the corresponding edge is selected according to a direction of the corresponding edge. The coverage area of the pixel is determined based on a sum of the fragment areas, the sum of the fragment areas having a value greater than a total area of the pixel.
