saving ellipse to image [message #80905]

Hi guys,
I'm trying to make an image in idl containing an ellipse that i can then do a bunch of stuff to. I did a bit of digging and found the tvellipse command...but that doesn't give me an image array (which i want), just puts the ellipse in a graphics window. So I'm wondering, is there some way that I can be sneaky and save this graphics window to a .tiff file or such so I can then read in this awesome image array that I'm looking for? Or maybe I am going about this in a very roundabout way and there is something simpler available? All the image save commands that I'm familiar with require that I already have an array to save :(

This is my example code for a random ellipse: tvellipse, 5,70,30,100, /FILL
