without remoting, and using string param only, encode the image as jpeg or png (depending on your requirement) . then convert it to base64 string which you can pass to the serlvet via post (or get, whatever) . Then decode at the backend accordingly as a jpeg file or png file which is you can make available to the user. This is not the fastest solution performance-wise but it does get the job done expecially for snapshots.

Since I don't think this can be done for instance saving to the desktop, I thought the next best solution would be to send the image to say a new browser window, possibly via a servlet? But I'm not sure how to do this or if this is the best solution. Any ideas or examples of how this should be done? Here is a little snippet of the method I use to encode the image into a byteArray: private function saveImage(e: ImageUpdateEvent ):void { var comp:UIComponent = e.comp; var imageSnap:ImageSnap shot = ImageSnapshot. captureImage( comp); var imageByteArray: ByteArray = imageSnap.data as ByteArray; imgSave.saveImage( imageByteArray, e.name+"-img. png"); }
