The region of interest is specified as an inset between screen edge and RoE on each side, expressed as a fractional value (between 0 and 0.5).
For instance, to have an area that occupies the middle 80% horizontal area and 50% vertical area, you would specify the region of interest as follows:
{ left: 0.1, right: 0.1, top: 0.25, bottom: 0.25 } Copy
{ left: 0.1, right: 0.1, top: 0.25, bottom: 0.25 }
(10% width inset on each side, 25% height inset on each side)
Bottom inset, relative [0 .. 0.5]
0.25 Copy
0.25
Left inset, relative [0 .. 0.5].
0.1 Copy
0.1
Right inset, relative [0 .. 0.5].
Top inset, relative [0 .. 0.5].
