Here is the caller graph for this function:

◆ init()

void BARE2D::Font::init	(	const char *	fontFile,
		int	size
	)

Creates font resources.

Parameters

fontFile	The file to load the font from. Should be .ttf
size	The size of the font (in points). This is basically just the quality of the font loaded. Has nothing to do with rendered size.
