Clip of a rectangular region of 200*120 pixels from the canvas. Then, draw a red rectangle. Only the part of the red rectangle that is inside the clipped area is visible:
Internet Explorer 9, Firefox, Opera, Chrome, and Safari support the clip() method.
Note: Internet Explorer 8 and earlier versions, do not support the <canvas> element.
The clip() method clips a region of any shape and size from the original canvas.
Tip: Once a region is clipped, all future drawing will be limited to the clipped region (no access to other regions on the canvas). You can however save the current canvas region using the save() method before using the clip() method, and restore it (with the restore() method) any time in the future.
