Html Codes: Canvas- Clipping, Effective Way for Drawing and Filling
HTML5 Canvas has effective feature for using the specific region of the context as the usable area, called Clipping. The benefit is that it can be used as a way for drawing or filling a defined part of an object or text, not its whole; so it is not important where and what you draw, the part that is inside the clipping region is shown. In the code below we have used HTML5 Canvas Clipping feature for filling part of a text and part of a triangle. Note that, for having more than one clipping region, you can save the current state of the context before call clip function and then restore it again. And be aware that we have made the clipping region visible for showing what has been done, but you can hide it if it isn't necessary to have more beautiful 2D graphics.
