Dear list, I've been using the following pcomb routine to fill in the perimeter corners of a square, 1200x1200 fisheye image with black to cover up the light spill inside the lens body and around the perimeter of the lens element:
pcomb -e 's(x):x*x;m=if(xmax*ymax/4-s(x-xmax/2)-s(y-ymax/2),1,0);ro=m*ri(1);go=m*gi(1);bo=m*bi(1)' input.hdr > output.hdr In order to maintain the absolute pixel values, which are much lower in the resultant 'output.hdr', would I need to use 'ra_xyze' piped into pcomb? I've tried various iterations but keep getting "illegal output resolution." As always thanks!
