Saving picturebox WITH backgroundimage to file

Question

is there any way to save a picturebox (Windows Forms) with it Backgroundimage to a file? I tried to store the picturebox.Image into a bitmap but its only the image itself, not the backgroundimage too.

You can combine two images using graphics or bitmap. There is a good example provided here

Bitmap

 using (var bitmap = new Bitmap(@"Images\in.jpg"))
    using (var watermark = new Bitmap(@"Images\watermark.png"))
    {
        //Make the watermark semitransparent.
        watermark.Channels.ScaleAlpha(0.8F);
    
        //Watermark image
        bitmap.Draw(watermark, 10, bitmap.Height - watermark.Height - 40, CombineMode.Alpha);
    
        //Save the resulting image
        bitmap.Save(@"Images\Output\out.jpg");
}

Graphics:

using (var bitmap = new Bitmap(@"Images\in.jpg"))
    using (var watermark = new Bitmap(@"Images\watermark.png"))
    {
        //Make the watermark semitransparent.
        watermark.Channels.ScaleAlpha(0.8F);
    
        //Watermark an image.
        using (var graphics = bitmap.GetGraphics())
        {
            graphics.DrawImage(watermark, 10, bitmap.Height - watermark.Height - 40, CombineMode.Alpha);
            //Save the resulting image
            bitmap.Save(@"Images\Output\out.jpg");
        }
    }
