Abstract
A method of generating a mask overlay for a display corresponding to a touch path, the method including receiving touch path data including touch points corresponding to the touch path, generating vertex points of a vertex array corresponding to the touch points, generating a polygon for a set of the vertex points to define edges of the touch path, determining start and stop edges of the polygon for a row of pixels, generating a list of bin offset values corresponding to the row and including bin offsets for indicating the edges by incrementing a bin offset for each of the start edges, and by decrementing a subsequent bin offset for each of the stop edges, generating an accumulator value corresponding to each of the pixels, determining whether the accumulator values are greater than or equal to zero, and generating the mask overlay by determining whether respective accumulator values is greater than zero.
