Constructor & Destructor Documentation

Font()

Font	(	const std::string &	filename,
		unsigned int	size,
		float	strokePercentage = 0
	)

Creates a font from filename in size px.

You may set strokePercentage to a positive or negative % value to increase or decrease the font size, without actually changing the position/size of the individual characters. This can be used to draw an outlined text by e.g. first drawing with a 5% stroke and then printing the same text with 0% (or even a negative stroke) over it.

Example: To increase the size of each character by 2px for a Font with a size of 20px, you would pass 10.f for strokePercentage.
