Note : If you are using one of the 3D bitmaps (as opposed to a standard 3D test pattern) you will have to make
sure that the 3D bitmap you use matches your selection of 3D formats and timing (resolution). In the example
above, a 3D Frame Packing bitmap is selected for 1280 x 720. Therefore you have to make sure that you
select that specific timing (i.e. 1280 x 720) and that specific 3D format structure (Frame Packing).
4.6 How to Scroll or Pan a Bitmap Pattern
This subsection describes how to scroll bitmaps on your 780C.
Note : The bitmap images are RGB and will not display properly on the 3G-SDI output.
4.6.1 Guidelines for Scrolling Bitmaps
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 780C 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 780C.
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 780C.
4.6.2 Procedures for Scrolling Bitmaps
Use the following procedure to scroll your bitmaps.
1. Touch select the desired bitmap image, e.g. Zone Plate image from the list of video patterns.
