Taking the screenshot itself is relatively straightforward. Once the scene has been rendered, the Direct3D device offers a GetRenderTarget function that returns a pointer to a Direct3D surface with the current scene. Using a SurfaceToBitmap function, the RenderTarget can be converted to a Bitmap object, which can then be saved as either a JPEG or PNG to disk. Below is an example of the code involved:
Bitmap screenshot = Funcs.SurfaceToBitmap(device.GetRenderTarget(0));
screenshot.Save(Frame.ToString() + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
screenshot.Dispose();
