DM8148. Display full HD image on display with smaller resolution

Hello TI' teams,

please let me known what is the best and simplest way for display ROI from captured HD image (1920x1080@30p) ,

means display the central portion of the source image with high resolution without scaling on display with resolution smaller, exact as on image below.

where is:

RED rectangle - display 1280x1024

BLUE tectangle - captured image: 1920x1080

I need display central portion of the captured frame without scaling, center of the HD image must be placed exactly on center of the display.

Is this possible generally?

Is SwMs link window position offset supports negative value?

I'm working with latest version of DVR-RDK and don't see any appropriated API's or link commands.

I would be very grateful for any help or advice.
