SYNOPSIS

make_mask [-s] [-1 .. -8] [-a] > outfile  

DESCRIPTION

make_mask creates an edge detector mask of a specified size for detecting edges at a variety of angles. This file can then be used as input to the HIPS program mask. The mask program performs a convolution of the image and this mask. For symmetric masks, odd numbers should be used. The default is -1 -3 -5 -7.
