While dragging a little bit into canvas, I successfully upload into a canvas a cropped clip of the image of a djvu page into it.source, just to crash into a DOM exception "The canvas has been tainted by cross-origin data" while attempting do access to pixel data with both getImageData() and toDataURL() methods.
Again, it seems a CORS issue.
Am I wrong? Is there some doc about this issue?
