Oh good! That works well. Thank you very much, Glynn. I had it backwards.
Hopefully my experience here can be of some help. The man page section for
--transform is a bit misleading. For example:
> The final device coordinates of the pixel are then calculated with the
so-called homogenic division

I implemented a transformation matrix to pinch the top of my screen 100px
on each side. My hope is for the resulting image to be an isosceles
trapezoid (trapezium) with the smaller base on top, larger base on bottom
filling the width of the screen, and with no part of the image missing or
drawn off
