Is this a new sweepstakes entry? Can I try?

First -- plot up a graph of anything you like in a window with the axes
defined however you want, with the ranges just so...

THEN: tvscl, imagearray, xoff=xxx, yoff=yyy

...such that your image just fills the plot window. This is a hack way
of doing it, but if I needed it done NOW, and I was only doing it once,
that's probably how I would approach it. I haven't checked, but there's
probably a graphics keyword you can use to specify just how many pixels
long and high your axes will be. You can then tvrd() your composite
image.

Good luck,
