I have raytracing that is 200x200 and I want to extract just the upper right 
20x20 pixel corner. I thought
+W200 +H200 +SC180 +ER20
would do the trick but the result is still a 200x200 file with all but my
desired square blackened out. But I don't want a 200x200 file. I want a
20x20 file that has that upper right corner and nothing else. Is there some
way to do this without resorting to manual cropping with an external
graphics program?
Thanx,
Apchar
