SciFigs::SciFigsGlobal::SciFigsGlobal ( )

You must create this object to initialize the library. Application must be created before calling this function.

void SciFigs::SciFigsGlobal::footprint	(	QPainter &	p,
		double	dotpercm,
		int	w,
		int	h
	)		`[static]`

Draw a small footprint (for all produced images). w and h are the width and height of the print area. dotpercm is the resolution of the medium.

void SciFigs::SciFigsGlobal::initPlugins	(	QSettings *	reg,
		bool	debug
	)		`[static]`

After first installion, make sure that the plugin path point to lib install directory so that all plugins provided with installation package are directly available.

Add current directory and install lib directory to search paths and search for plugins
