Example

[Visual Basic, C#] The following example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a FontFamily object.
  • Gets the em square height for that font family.
  • Draws the value of the em height to the screen as text.
[Visual Basic] 
Public Sub GetEmHeight_Example(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
        
[C#] 
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));
