Yeah, you can't do this unless CORS is enabled on the remote server. It's a security issue.
The solution is to enable CORS on the remote server. Sorry about that!
Ooh or actually in this case, you can start a local fileserver and then use that instead of file://
. Last I checked, this is how Cordova is getting around security issues with WKWebView (which is pretty broken when it comes to loading local file://
URLs).
In my Cordova app I am testing WKWebView, which implements much stricter CORS checks than UIWebView.
I capture a photo from the Cordova camera plugin (which outputs a file:// uri) then load that into an Image object, if I then pass that image object to blobUtil.imgSrcToBlob I get a DOM Exception 18.
This all works correctly using UIWebView.
I guess this is because the file system does not attach CORS headers and so the blobUtil cannot call canvas.toDataURL
