clip

clip

clip Unsets the clipping region (draws to the full screen)

clip x y width height Sets the clipping region

Parameters

• x, y : coordinates of the top left of the clipping region
• width : width of the clipping region in pixels
• height : height of the clipping region in pixels

Description

This function limits drawing to a clipping region or 'viewport' defined by x,y, width, and height. Any pixels falling outside of this area will not be drawn.

Calling clip() with no parameters will reset the drawing area to the entire screen.
