DuckLink Screen Capture (AKA: DuckCapture) comes with four capture modes that make screen capture easy! Capture a window on your screen, region of your screen, or the contents of a tall web page that scrolls. Don’t waste time cropping your captures. DuckCapture exactly what you need.
Capture Modes make it easy: in addition to full screen capture, the other three useful modes:
Capture a window
Get just the window, not the stuff behind or around it.
Capture a region
Draw a Box on the screen and capture whatever is inside.
