If you set the sensor to a very small size (e.g. QQQVGA), then it doesn’t fill the LCD in either dimension. I realize the aspect ratio is wrong and so either black bars or cropping would be required, but you still don’t have to suffer black bars on both axes. That’s a waste of space. Is there a way to instruct the LCD to fill the display with the image? I tried passing ROIs to display, both inside and outside (negative origin and width/height greater than the assigned sensor image) and neither approach worked.
