Question

I am trying to use the graphics object to load an image in and then rotate it (either portrait or landscape) and then display it in a panel (not a picture box).

How would I load the graphics in the panel? Also what would be the simplest way to do a landscape or portrait rotation on the graphics object?

GDI must be used to rotate and work with the image, I need a way to get the Graphics object into the panel.

Answer 1

Use the Paint event of the Panel:

    private void panel1_Paint(object sender, PaintEventArgs e)
    {
        int angle = 90;
        Graphics g = e.Graphics;
        Image i = new Bitmap(@"C:\Jellyfish.jpg");
        g.TranslateTransform((float)i.Width / 2, (float)i.Height / 2);
        g.RotateTransform(angle);
        g.TranslateTransform(-(float)i.Width / 2, -(float)i.Height / 2);
        g.DrawImage(i, new Point(0,0));

    }
