Definition

Namespace:

System.Drawing

Assembly:

System.Drawing.Common.dll

Package:

System.Drawing.Common v8.0.0

Source:

Image.cs

Gets the bounds of the image in the specified unit.

public:
 System::Drawing::RectangleF GetBounds(System::Drawing::GraphicsUnit % pageUnit);

public System.Drawing.RectangleF GetBounds (ref System.Drawing.GraphicsUnit pageUnit);

member this.GetBounds : GraphicsUnit -> System.Drawing.RectangleF

Public Function GetBounds (ByRef pageUnit As GraphicsUnit) As RectangleF

Parameters

pageUnit

GraphicsUnit

One of the GraphicsUnit values indicating the unit of measure for the bounding rectangle.

Returns

RectangleF

The RectangleF that represents the bounds of the image, in the specified unit.

Examples

The following code example demonstrates how to load a bitmap from an Icon handle, using the GraphicsUnit enumeration, and how to use 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
