Subject: Re: [DOTNET-WINFORMS] From Graphics to Image

SORRY TO INTERRUPT....
 but there seems to be some misunderstanding..

set the image property of the picture box to the image after editing the
image

  Bitmap bmp = new Bitmap(pictureBox1.Width, pictureBox1.Height);
            Graphics g = Graphics.FromImage(bmp);
            g.Clear(Color.Blue);
            pictureBox1.Image = bmp;
            pictureBox1.Refresh();

The first part is right, but if "g" is the Graphics object obtained
via Graphics.FromImage(b), then g.DrawImage won't paint the image on
the screen. Instead, it can be used to paint a different image on the
graphics object (which in turn paints on "b").

To show the image on the screen, you can use a PictureBox or a Paint
event's PaintEventArgs.Graphics.DrawImage().
