There are two ways you can animate (move) a bitmap image: 1) image shifting (scrolling); 2) panning. You can
shift or scroll a bitmap image that you have imported into the 780B by modifying the X and Y parameters or by
dragging and panning. When you use the X and Y parameters, you are limited to linear scrolling. With panning
you can move the image in non-linear motions.
You can only scroll bitmaps whose overall pixel resolution is smaller than the resolution of the active format and
you can only scroll them within the bounds of the resolution of the active format. You cannot scroll the standard
test patterns in the 780B.
In order to scroll a bitmap the name of the bitmap has to be "zp.bmp." But you can scroll any bitmap. You just
have to make sure that you have named it "zp.bmp" (without the quotes). The zone plate bitmap is the only
bitmap that comes standard with the 780B.
