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
MGP Series 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
the size (in kBytes) of the image bitmap file and the resolution. The following table shows
examples of the number of images you can store based on resolution.
Resolution 640 x 480 800 x 600 1024 x 768 1280 x 1024 1400 x 1050 1600 x 1200 1080p
Image Size (kB) 900.00 1406.25 2304.00 3804.00 4306.64 5625.00 6075.00
Total Images 16 11 6 4 3 2 2
To calculate the size of a bitmap file for any image of any specified size, use this formula:
file size (in kilobytes) = ( horizontal x vertical x 3) + 54 ( file header ID )
