    End Sub

The above example requires a textbox and picturebox controls on the form. Code creates the objects of the Fontconverter and Font classes. We initialize the graphics object from the CreateGraphics() method and in the last we are using the Graphics.DrawString() method to draw the text of the textbox control on the picturebox.

    1. textSize is the object of the SizeF class that represents the ordered pair of the width and height (typically width and height of the rectangle).

      So you can also use the last line as :

      g.DrawString(txtText.Text, myFont, myForeBrush, _

      New RectangleF(0, 0, textSize))
