Description

What I am trying to do is hash an image. Unfortunately (using SDK 1.4.1.1 and iOS 3.2) it does not appear that there is any way to access the raw data (in an array of bytes or as a string etc). So the built in MD5 digest function throws an error, and other javascript based hashing algorithms are not useful either.

For the Blob object, access to the raw data should be provided.

Thank you.

Cannot reproduce SDK 2.2.0.014b86f on iPhone Sim 5.1. Test code:

   var image = Ti.UI.createImageView({
   	image:'images/chat.png'
   });
   	Ti.API.info(Ti.Utils.md5HexDigest(image.toBlob()));
