ABSTRACT:
A computer program product for inputting a desired soft edge into a digital mask comprises a computer readable storage medium having a computer program stored thereon for performing the steps of selecting the desired profile having a predetermined hard-edge position and transition width; selecting a distance from the hard-edge position to a boundary of the transition width for forming a kernel distance; determining a minimum distance to the hard edge for each pixel within the kernel distance from the hard edge; substituting values from the desired profile for each pixel within the kernel distance from the hard edge using the minimum distance of the pixel from the hard edge.
