Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a FontFamily.

  • Gets the em square height for that font family.

  • Draws the value of the em height to the screen as text.

public:
   void GetEmHeight_Example( PaintEventArgs^ e )
   {
      // Create a FontFamily object.
      FontFamily^ emFontFamily = gcnew FontFamily( "arial" );

      // Get the em height of the font family in design units.
      int emHeight = emFontFamily->GetEmHeight( FontStyle::Regular );

      // Draw the result as a string to the screen.
      e->Graphics->DrawString( String::Format( "emFontFamily.GetEmHeight() returns {0}.", emHeight ),
            gcnew System::Drawing::Font( emFontFamily,16 ), Brushes::Black, PointF(0,0) );
   }
public void GetEmHeight_Example(PaintEventArgs e)
{
    // Create a FontFamily object.
    FontFamily emFontFamily = new FontFamily("arial");
             
    // Get the em height of the font family in design units.
    int emHeight = emFontFamily.GetEmHeight(FontStyle.Regular);
             
    // Draw the result as a string to the screen.
    e.Graphics.DrawString(
        "emFontFamily.GetEmHeight() returns " + emHeight.ToString() + ".",
        new Font(emFontFamily, 16),
        Brushes.Black,
        new PointF(0, 0));
}
Public Sub GetEmHeight_Example(ByVal e As PaintEventArgs)

    ' Create a FontFamily object.
    Dim emFontFamily As New FontFamily("arial")

    ' Get the em height of the font family in design units.
    Dim emHeight As Integer = _
    emFontFamily.GetEmHeight(FontStyle.Regular)

    ' Draw the result as a string to the screen.
    e.Graphics.DrawString("emFontFamily.GetEmHeight() returns " & _
    emHeight.ToString() + ".", New Font(emFontFamily, 16), _
    Brushes.Black, New PointF(0, 0))
End Sub

Remarks

Em square is a typography term that refers to the rectangle occupied by the font's widest letter, traditionally the letter M.
