deleting part of an image?Started by:Arp, 02/28/2010 04:44PM
Hi!

Is there a task which lets me manipulate
parts of an image without trimming it?
for example, I want to to set all pixel
values in a the section 100:200,100:200
to 0.

I tried imcopy, but I think that only
allows me to copy a section.
thx.

bpmedit is missing from the image.tv

The good news is that there may not be
many (if any) of these omissions left in
IRAF proper. These menus are rather
accurate considering they aren't
generated on the fly.
