endLayer()

Restores the global draw functions rect() etc. so that they operate on the canvas again, instead of the Graphics created by or passed as an argument to beginLayer(). This function also draws the Graphics onto the canvas – although this behavior can be suppressed.

Syntax:

endLayer()

Restores the global draw functions, and draws the Graphics onto the canvas unless the argument to enterGraphics() was a Graphics.

endLayer(x, y, [width, height])

Restores the global draw functions, and draws the Graphics onto the canvas.

endLayer(false)

Restores the global draw functions. Does not draw the Graphics onto the canvas.
