The following code example demonstrates how to load a bitmap from an Icon handle, using the GraphicsUnit enumeration, and the use of the Round method to draw the rectangle bounds of a bitmap.
This example is designed to be used with Windows Forms. Create a form that contains a button named Button2. Paste the code into the form and associate this method with the button's Click event.
private void Button2_Click(System.Object sender, System.EventArgs e) { Bitmap bitmap1 = Bitmap.FromHicon(SystemIcons.Hand.Handle); Graphics formGraphics = this.CreateGraphics(); GraphicsUnit units = GraphicsUnit.Point; RectangleF bmpRectangleF = bitmap1.GetBounds(ref units); Rectangle bmpRectangle = Rectangle.Round(bmpRectangleF); formGraphics.DrawRectangle(Pens.Blue, bmpRectangle); formGraphics.Dispose(); }
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
