Name
Canvas.getContext( ): return a context for drawing on the canvas
Synopsis
CanvasRenderingContext2D getContext(StringcontextID)Arguments
-
contextID This argument specifies the type of drawing you want to do with the canvas. Currently the only valid value is “2d”, which specifies two-dimensional drawing and causes this method to return a context object that exports a 2-D drawing API.
Returns
A CanvasRenderingContext2D object with which you can draw into the Canvas element.
Description
Returns a context representing the type of context to use in drawing. The intent is to provide different contexts for different drawing types (2-D, 3-D). Currently, the only one supported is “2d”, which returns a CanvasRenderingContext2D object that implements most of the methods used by a canvas.
