What do you mean by default range? Who's default range?

Why would IDLgrImage only "accept and handle" 1 to 1000?
If you set up your view so that it is only 1000 units wide, your image will
be clipped at the edge. If you set the dimension of your image to 1000
units wide your image will be scaled.
Can you give us some details?

No worries. As far as I can tell, most of us in this group are already
confused ;)
