I think the security concern is that a rogue Silverlight app could request images from sites the browser has authenticated on (your bank?), and read those pixels and send the bits up to a rogue server.
I can see the pretext (or is it context?). But the rogue SL application can also request the same Jpg as a byte stream from said bank, and send the Jpg as a byte stream to a rogue server?
Visit http://www.tagxedo.com, a Silverlight-based word cloud generator. If you like it, please help me spread the word!
I'm pretty sure this is _not_ possible in SL3 Beta. Because we do not have Pixel access after calling Render(). But maybe by final RTW (sorry I kept saying RTM, I should really be saying RTW!)
I know this topic is old, but I made a library for manipulating images: [url]http://imagetools.codeplex.com[/url], you can save your writeable bitmap with my library as png, jpeg or bmp, just as you want
