SetMap
Function Defines the region of the magnified image to be displayed by a specified output.
Format SetMap=<output number>,<top left horizontal position>,<top left vertical position>,
<horizontal size>,<vertical size>,0\r
Arguments <output number> is the output channel number:
0 = Output 1
1 = Output 2
2 = Output 3
3 = Output 4
The two <…position> and two <…size> values are measured in pixels and define
the boundary of the selected output on the target display. These are measured
relative to the source Clip (see SetClip). The <…size> values should always
match the screen resolution of each output (see SetOpMode).
Example SetMap=0,0,0,1024,768,0\r
SetMap=1,0,1024,1024,768,0\r
SetMap=2,0,768,1024,768,0\r
SetMap=3,1024,768,1024,768,0\r
Maps the outputs to a 2×2 target display using XGA display devices.
