Security Error #2

Open ghost opened 13 years ago

Hi there,

I am working with nude.js to scan a series of images from Flickr. Now everything goes just fine up to the point where I call nude.scan. With that line I get the following security error in Chrome:

Uncaught Error: SECURITY_ERR: DOM Exception 18

And in Firefox:

Security error" code: "1000 http://www.local.com/labs/nude/js/nude.min.js Line 1

Searched around a bit and found an entry on Stackoverflow that mentions the following: "Error 1000 usually means you are trying to change something in the DOM which is not allowed." - http://goo.gl/zP1kl

I have tried running this via just plain http://localhost as well as mapped a domain name www.local.com to 127.0.0.1 using the hosts file but, in both cases I get the security error.

Also created a Fiddle you can check out here: http://jsfiddle.net/ossreleasefeed/Crzz3/

This error is because you cannot call getImageData() on a canvas that contains an image form another domain. I don't know how to bypass this security error but is really silly since I cannot scan images from other sites.

I thought as much, would be awesome to find a way to do this cross domain. I will do some experimentation and let you know if I find something.

Use --allow-file-access-from-files flag on launching chrome. Eg on linux terminal: google-chrome --allow-file-access-from-files.

Hopefully not too late :D
