     -v i    repeat vertically i times, default 1.
     -a i    repeat i times perpendicular to smallest dimension;
             default 10; and 1 time perpendicular to the largest dimension;
             overrides -h and 0v.
     -l i    limit size in repeat direction to i; default 256; only applies
             if -a is in force.
     -p s    prefix to prepend to image name, default "rep_".  Can
             be empty string, in which case the input image is
             overwritten.
