Description

canvas.toDataURL("image/png") works very well on chrome and firefox but for IE it does not work. When canvas.toDataURL("image/png") gets called a Security error gets thrown.

Contributor guide

Research direction
Investigate why IE throws a security error when calling canvas.toDataURL. Check if the canvas has been tainted by drawing an image from a different origin. Verify that images are served with proper CORS headers and crossOrigin attribute is set. For IE, ensure cross domain access is enabled.
