Abstract
A system includes a first computing device that includes a memory configured to store instructions. The first computing device also includes a processor to execute the instructions to perform a method that includes receiving data representing a collection of line segments that represent a glyph. The method also includes, for each line segment, defining a cell that substantially encapsulates the line segment. At least one side of the cell is defined by bisecting an angle defined by the line segment and an adjacent line segment. The method also includes determining a value for a portion of the defined cell based upon the distance between the portion of the cell and the corresponding line segment.
