Background Capture Menu
The Background Capture menu allows you to capture the image currently on the output
screen and save it as a bitmap (.bmp) file with one of 16 designated image names. You can
then recall the image and use it as a background.
Background Capture also can be done via the Windows-based control software (see the
Windows-based Control Program help file).

Memory space for background files
The MGP Pro has 16 MB of user storage space that can be used for saved backgrounds
and uploaded user web pages. The number of images that you can save depends on

examples of the number of images you can store based on resolution.
