* * Creates a GWTCanvas element. Element type depends on deferred binding. * Default is CANVAS HTML5 DOM element. In the case of IE it should be VML. * * <p> * Different coordinate spaces and pixel spaces will cause aliased scaling. * Use <code>scale(double,double)</code> and consistent coordinate and pixel * spaces for better results. * </p> * * @param coordX the size of the coordinate space in the x direction * @param coordY the size of the coordinate space in the y direction * @param pixelX the CSS width in pixels of the canvas element * @param pixelY the CSS height in pixels of the canvas element

Method Details

init(self, coordX=300, coordY=150, pixelX=300, pixelY=150, **kwargs)
(Constructor)

* Impl Instance. Compiler should statify all the methods, so we * do not end up with duplicate code for each canvas instance.

Overrides: object.__init__

Instance Variable Details

coordHeight

* * Sets the coordinate space of the Canvas. * <p> * This will erase the canvas contents! * </p> * * @param width the size of the x component of the coordinate space * @param height the size of the y component of the coordinate space

coordWidth

* * Set the current Fill Style to the specified color gradient. * * @param grad {@link CanvasGradient}
