4.7 How to Pan (Scroll) a Bitmap Image
This subsection describes how to pan bitmap test patterns on your 780B.
4.7.1 Guidelines for Panning Bitmaps
There are two ways you can animate a bitmap image: 1) image shifting (scrolling) 2) panning. Here are the
rules and capabilities:

In order to scroll a bitmap the name of the b
itmap 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.

You can pan bitmaps whose resolution is lower than the active format but only within the range of the
excess space in the raster. You cannot pan the standard test patterns in the 780B.
4.7.2 Procedures for Panning Bitmaps
Use the following procedure to pan your custom bitmaps.
1. Select by double touching, the desired bitmap image, e.g. Zone Plate image from the list of video patterns
(shown below).
