Silly me. I've been doing to much Python programming recently -- using
"#" instead of ";" for comments.

Presumably you want to display the image. In that case, use something like
IMDISP which automatically resizes the image to fit the graphics window:

If you want to resize it such that the new dimensions are integer
multiples of the original dimensions, use rebin(). If the new
dimensions are not integer multiples of the original, use congrid().
# Get screen size
size = device, GET_SCREEN_SIZE=resolution
# Resize the original image
new_image = congrid(orig_image, resolution[0], resolution[1])
# Display the new image
window, XSIZE=resolution[0], YSIZE=resolution[1]
tv, new_image

Dear Benard
please have a look at rebin and congrid in the documentation
To get information about your screensize you could use the following
command:
device,get_screen_size=screen_size
screen_size is the size of your screen.
