Base64 encode and image in Adobe Air

Question

Hi there

I am writing an adobe air app in html/javascript and I am trying to base64 encode an image so I can add it to and XML RPC request. I have tried many methods and nothing seems to work.

I see that actionscript has a Base64Encoder class that look like it would work, is there any way to utilize this in javascript?

Thanks,

Jordan

Thanks @some for the link.

I used the btoa() function to base64 encode image data like this:

var loader = new air.URLLoader(); loader.dataFormat = air.URLLoaderDataFormat.BINARY; loader.addEventListener(air.Event.COMPLETE,function(e){ var base64image = btoa(loader.data); }); var req = new air.URLRequest('file://your_path_here'); loader.load(req);

I was trying to upload an image using metaWeblog.newMediaObject, but it turns out that the data doesn't need to be base64 encoded, so the binary value was all that was needed.
