Once a canvas render extension is created, a Lua canvas object can be accessed using the gre.get_canvas call. In this documentation the object returned from the gre.get_canvas functions will be identified as a CANVAS object. Methods associated with the CANVAS object must be invoked using the Lua colon (:) notation for example CANVAS:stroke_rect
