member this.DpiX : single
Public ReadOnly Property DpiX As Single

Property Value

The value, in dots per inch, for the horizontal resolution supported by this Graphics.


The following method shows the use of the DpiX and DpiY properties. This example is designed for use with a Windows Form. To run this example, paste it into a form that contains a ListBox named listBox1 and call this method from the form's constructor.

   void PopulateListBoxWithGraphicsResolution()
      Graphics^ boxGraphics = listBox1->CreateGraphics();

      // Graphics* formGraphics = this->CreateGraphics();
      listBox1->Items->Add( String::Format( "ListBox horizontal resolution: {0}", boxGraphics->DpiX ) );
      listBox1->Items->Add( String::Format( "ListBox vertical resolution: {0}", boxGraphics->DpiY ) );
      delete boxGraphics;
private void PopulateListBoxWithGraphicsResolution()
    Graphics boxGraphics = listBox1.CreateGraphics();
    Graphics formGraphics = this.CreateGraphics();

    listBox1.Items.Add("ListBox horizontal resolution: " 
        + boxGraphics.DpiX);
    listBox1.Items.Add("ListBox vertical resolution: " 
        + boxGraphics.DpiY);

Private Sub PopulateListBoxWithGraphicsResolution()
    Dim boxGraphics As Graphics = listBox1.CreateGraphics()
    Dim formGraphics As Graphics = Me.CreateGraphics()

    listBox1.Items.Add("ListBox horizontal resolution: " _
        & boxGraphics.DpiX)
    listBox1.Items.Add("ListBox vertical resolution: " _
        & boxGraphics.DpiY)

End Sub
