Can I use getImageData(), in the place of .toDataURL()? If yes, please give me way for using this, because .toDataURL() is generating an error for IE 7/8.
If you are using excanvas to support canvas in IE7/8 then
"ExCanvas does not support any of the ImageData functions (createImageData, getImageData, putImageData)."
Please see the discussion at the following link
