Exceptions

Exception	Condition
InvalidCallException	The method call is invalid. For example, a method's parameter might contain an invalid value.

Remarks

This method does not render text to the device; the DrawText method must still be called to render the text. However, preloading text into video memory causes DrawText to use substantially fewer CPU resources.
