I think you're right. I think the options for image processing on the client side are currently limited to VML ( http://en.wikipedia.org/wiki/Vml http://en.wikipedia.org/wiki/Vml ) for IE or for Safari/Firefox/Opera, SVG or Canvas ( http://en.wikipedia.org/wiki/Canvas_ http://en.wikipedia.org/wiki/Canvas_(HTML_element) ) and from the little bit of tinkering I've done with both, I don't think you can read the values of pixels of image buffers with any of those options. If anyone can disprove this I'd be very glad to hear it. You can with Flash or Java applets but both of those ideas have other problems as well. It certainly would be useful if it were possible. I've also been trying to figure out how to control a scanner from in the browser. I'd like to have something on a page which would scan a document, display the image in the browser, and upload it to a server. I was hoping I could do it with Flash, because Flash does have a TWAIN interface, but I've not been able to get Flash to recognize scanner devices, only cameras. I'm starting to think applets may be the answer to that, but that seems like a long road to start on. Does anyone have any ideas about controlling scanners within browsers?
