Example

Here we paint a blue rounded rectangle on the bitmap, which is auto sized. We also set the size of the corners to 32 pixels - the default is 16.

Note that the bitmap size is set to 250x250 because we center the image (25 + 200 + 25 = 250). Size the bitmap manually if this is not what you want.

[C#]using (Bitmap bm = new Bitmap(500, 500)) {
  using (Graphics gr = Graphics.FromImage(bm))
    gr.FillRoundRectangle(Brushes.Blue, new RectangleF(50, 50, 400, 400), new SizeF(64, 64));
  bm.Save(Server.MapPath("IG8_Graphics_FillRoundRectangle.png"));
}
