A computer program product for creating a soft edge in digital images comprises a computer readable storage medium having a computer program stored thereon for performing the steps of independently receiving a transition width that indicates the width of the soft edge from a computer interface; independently receiving a desired position of a hard-edged boundary from the computer interface; receiving a function of the soft edge which uniquely corresponds a pixel value to a scaled pixel location in the digital image from the computer interface; and calculating an absolute profile of the soft edge, which uniquely corresponds a pixel value to a pixel location in the digital image, from the received transition width, position of the hard-edged boundary and function.
