Extron electronic Multi-Graphic Processor MGP 464 Manual De Usuario

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”).

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.
