I have an image that I want to print out on a very large scale and get
decent printing resolution, and I also hope to print a few scenes on
polyhedra cutouts (just for fun). All that is secondary. My real
question is if my image size is, say 800 by 600, and I want to render
rows 20 through 80 and columns 200 by 300 (or any subregion, really) I
get a final image size of 800 by 600 pixels, most of it blank, with only
rows 20 through 80 and columns 200 by 300 filled in.
Is it possible to get POV-Ray to give me an image 61 pixels high and 101
pixels across when rendering like this?

Isn't this done by using the +sc +sr +ec +er commands?

DOH! Just researching this and I learn about the bit-depth switch! Reading
the docs is a good thing! :)

DOH! again! :) You mean output a cropped image? I don't think so.

Yeah, that was the gist of it. If the image is (for example) 1000 by 1000
pixels, and I tell it to render a subset, the final image is still 1000 by 1000
pixels. If I had the memory available to me, I'd render the huge scene file and
then find another cheap way to print it.

Why not just "point_at" and zoom in?

I'm worried about deforming the image by doing that. Now I have been thinking
about doing that and putting the individual images on a half sphere so if you
put your face in it you would get more of an effect of being immersed into the
scene, but it wouldn't make anything pop out in real 3D.
