Source Processing Commands
SetClip
Function Specifies the source to be placed on the target display and sets the magnification
to be applied.
Format SetClip=<channel>,<top left horizontal position>,<top left vertical position>,
<bottom right horizontal position>,<bottom right vertical position>,0\r
Arguments <channel> is the input channel number:
0 = Input 1 (RGB)
1 = Input 2 (RGB)
2 = Input 3 (VIDEO / S-VIDEO)
3 = Input 4 (VIDEO)
The four <…position> values are measured in pixels and define the boundary of
the selected source on the target display. The source is magnified to fit the
specified area. To make the source fill the target display area, this will always be
relative to the output mode resolution. For example, on a 2×2 display using XGA
(1024×768) screens:
<top left horizontal position> = 0
<top left vertical position> = 0
<bottom right horizontal position> = (2 × 1024) – 1 = 2047
<bottom right vertical position> = (2 × 768) – 1 = 1535
Example SetClip=2,0,0,2047,1535,0\r
Places source input 3 on a 2×2 display using XGA display devices.
