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
chapter 4, “Software Configuration and Control”) and the MGP 464 Web pages (see
chapter 5, “HTML Configuration and Control”).

Memory space for background files
The MGP 464 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 kB) of the image bitmap file and the resolution. The
following table shows 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)
Saving a background to memory
To save the current image to memory for use as a background,
1
. Press Menu repeatedly until the Background Capture screen is displayed.
2 . Press Next repeatedly until the Save Background to Memory submenu screen
is displayed.
3 . Rotate either Adjust knob to select a background file name (bkg01.bmp
through bkg16.bmp) with which to save the image.
N You can save the background image only under one of the file names on this
menu (you cannot make up a different name for it). However, images loaded via
the Windows-based control software (IP Link File Manager) or via the MGP 464
Web pages may be given any desired file names. See chapter 4, “Software
Configuration and Control,” for information on using the Windows-based
software, and chapter 5, “HTML Configuration and Control,” for information
on using the Web pages.
If you do not want to save the image, select None on the LCD screen, then
press Next. The Recall Background submenu screen is displayed.
