I'm trying to create a marker from a bitmap, which can be done with SymbolFactory.ConstructMarkerFromFileAsync(). Is there a way to do the same thing with an in-memory bitmap instead of a file? Either a Stream or a System.Drawing.Bitmap object would be fine. For now I'm just writing the image to a temporary file and reading it from there, but that's just kind of dirty and hackish in my opinion. A minor detail, I know, but it irritates me when SDKs operate on files instead of streams!
