Examples

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.

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( units );
 Rectangle bmpRectangle = Rectangle::Round( bmpRectangleF );
 formGraphics->DrawRectangle( Pens::Blue, bmpRectangle );
 delete formGraphics;
}

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();
}

Private Sub Button2_Click(ByVal sender As System.Object, _
 ByVal e As System.EventArgs) Handles Button2.Click

 Dim bitmap1 As Bitmap = Bitmap.FromHicon(SystemIcons.Hand.Handle)
 Dim formGraphics As Graphics = Me.CreateGraphics()
 Dim units As GraphicsUnit = GraphicsUnit.Point
 Dim bmpRectangleF As RectangleF = bitmap1.GetBounds(units)
 Dim bmpRectangle As Rectangle = Rectangle.Round(bmpRectangleF)
 formGraphics.DrawRectangle(Pens.Blue, bmpRectangle)
 formGraphics.Dispose()
End Sub
