BGTRANSPARENCY

"1" to enable or "0" to disable. Enables terminal transperancy. BGVIEWPORT "1" to enable or "0" to disable. This must be set in conjugation with IMAGEFILE From the Eterm man page: "

This activates a special Eterm mode which is hard to describe in words. Basically, imagine the effect you get with pseudo-transparency, where the desktop background moves through the Eterm window as you move the window, so that it always aligns with the desktop image. Now, imagine the same effect, but the image used isn't the desktop image but any pixmap you choose. The image is scaled or tiled up to the size of the desktop, and dragging the Eterm around the screen reveals different portions of the image as you move, much like a small viewport window in a ship or submarine does. The effect is especially keen if you open several Eterms in this mode with the same image."

Eterm only.
