C Language Development Kit/Functions/GetFontSize

Description	Returns the width and the height of a character of the current font, measured in pixels.
Syntax	void getfontsize(unsigned int * height, unsigned int * width);
Arguments	unsigned int * height The height of the characters in the current font, measured in pixels. unsigned int * width The width of the characters in the current font, measured in pixels.
Returns	None
Remarks	This function is useful when you want to know how many characters fit on a line, or how many lines fit on the display. This information is necessary when you build a menu system that can be used for different font sizes. This function is not available on the DWT7133.
