示例1: GetEmHeight_Example
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));
