Get frame buffer region size

[jovcem]

How to get the region numbers (210;752;560;100 from the right image (frame buffer)?
When using the function from the picture I get different set of coordinates.

The coordinates you get are pixels from the screen edge.
They will work just fine if you pass them back to the function to create the region again.
You'll need to get the image plane extents, and do simple math, to get the absolute pixel value.

To add to this - in Update 2 we fixed this function and now it returns what you see on screen.
