Claim 6:
7. The computer-implemented method of claim 1, wherein utilizing the one or more sub pixel subregions to determine the combined area of sub pixel subregions for each pixel comprises:
generating, by the one or more processors, one or more paths, based on navigating along each edge of the pixel, starting with the edge where a current point is located, in a pre-determined direction, toward a next vertex of the pixel, until each sub pixel subregion is counted, the navigating comprises:
determining, by the one or more processors, if any of the sub pixel subregions are uncounted;
based on determining that at least one sub pixel subregion is uncounted, generating a path comprising contiguous points comprising the at least one sub pixel subregion, the generating comprising:
appending, by the one or more processors, a last coordinate of the uncounted sub pixel subregion to the path, where the last coordinate comprises a current point;
determining, by the one or more processors, an edge of the pixel where the current point is located;
navigating, by the one or more processors, in the predetermined direction toward the next vertex;
based on the navigating, determining, by the one or more processors, if a starting point to a segment of another uncounted sub pixel subregion is on the edge before the next vertex;
based on determining that no starting point is on the edge before the vertex, adding coordinates of the next vertex to the path and continuing the navigating in the predetermined direction toward the next vertex; and
based on determining that there is a starting point to a segment of another uncounted sub pixel subregion on the edge before the vertex, navigating through the pixel along a segment to an intersection between a point of the contiguous points comprising the other uncounted sub pixel subregion and an edge of the pixel, adding the contiguous points to the path, marking the other uncounted sub pixel subregion as counted, and progressing from the intersection in the pre-determined direction to another vertex.
