-<dl><dt><a name="ScreenFinder-GetNext">GetNext</a>(self)</dt><dd><tt>Gets the next screen image.

-

-Returns:

-  A numpy matrix containing the screen surrounded by the number of border

-  pixels specified in initialization, and the location of the detected

-  screen corners in the current frame, if a screen is found. The returned

-  screen is guaranteed to be the same size at each frame.

-  'None' and 'None' if no screen was found on the current frame.
