FileSubmitter in Chrome

[Camaron]

Hello

I am trying to write a Chrome extension that allows to resize an image
before uploading it.
So far I've used Gears to open and scale the image, now I can't add to
the original <input type="file"/> element, since FileSubmitter is only
implemented in IE and Firefox.

Is there any hope for me to set the file of an <input type="file"/> to
the URL of a captured blob by any other means?

You can try to use Gears.XMLHttpRequest to upload the blob.

I can't use XMLHttpRequest since I need to use the original form,
which could be any form from any website.

Yes, you can emulate classic multipart form submissions with Gears.

I've just created GearsUploader project on bitbucket:

Maybe GearsMultipartForm.js is what you need:

Your class is quite elegant. I wrote something similar recently:
