Remove Watermark, after initializing it in the canvas.

[ahmad6242]

Hello Everyone.
Just wondering after i place the Watermark using the Code below.

var newImage = new Image()
 newImage.src = e.target.result;
lc.setWatermarkImage(newImage);

Now i just want it to be removed, Can i achieve this somehow. Please help.
if i put empty src image like this it did not affect anything at all, it just keeps the old watermark...

var newImage = new Image()
lc.setWatermarkImage(newImage);
