Is there a way to open an image in paint.net from a memory stream (or something similar) and when saved, send it back as a memory stream? I want to use paint.net as an external editor for images in a winforms c# application but the images are stored in a database and instead of saving them to disk and pick them up when changed I would like to find a more elegant way to edit them. And of course because paint.net is a very good editor.
