Detailed Description

The GlsRuntimeFontBase class provides a specific font face for use within the GL Studio. The font face is determined at construction time by the parameters passed in by the creator of the GlsFontBase instance. Specific instances should be wrapped in a singleton object wrapper, as there is no reason to have more than one instance of the exact same face (meaning font family, style, and point size.)

Once instanced, a GlsFontRenderer object can be used to render characters in Open GL at specific locations and with several different text effects.

Constructor & Destructor Documentation

GlsRuntimeFontBase	(	const char *	family,
		const char *	style,
		const unsigned int	ptSize,
		const char *	fontPath,
		const unsigned int	maxCharWidth,
		const unsigned int	maxCharHeight,
		const unsigned int	descender
	)

Class Constructor

Parameters

family	the family name of the font.
style	the style name of the font.
ptSize	the point size of the font.
fontPath	the path and filename of the font file to load.
maxCharWidth	the maximum width of the largest character.
maxCharHeight	the maximum height of the largest character.
descender	the maximum descender of the largest character.

~GlsRuntimeFontBase ( )

protected

Class Destructor. This is protected so that no one can delete a font except via the font manager GlsFontMan. It is not virtual because we want to avoid calling destructors on unloaded font code, and it is not needed.
