The viewer is a very simple application for now (any help for its
development is welcome). It doesn't let you choose the region of
interest nor the pixel format.
You have to use the command line for now.
You can get the current walues using:
arv-tool-0.2 control PixelFormat Width Height
And set them using:
arv-tool-0.2 control PixelFormat=Mono8 Width=1616 Height=1216
