dumpInfo()

void dumpInfo

(

)

Dump information about this font to the console.

exportStrip()

void exportStrip	(	const char *	fileName,

		U32	kerning
	)

Export to an image strip for image processing.

forcePlatformFont()

void forcePlatformFont ( PlatformFont *  pf )

inline

Override existing platform font if any with a new one from an external source. This is primarily used in font processing tools to enable trickery (ie, putting characters from multiple fonts in a single GFT) and should be used with caution!

	)

Import an image strip generated with exportStrip, make sure parameters match!

isAlphaOnly()
