Detailed Description

Subclass of RegionShape used for drawing text.

Text uses RegionShape's label property.

Constructor & Destructor Documentation

RSText::RSText	(	double	x,
		double	y,
		const String &	text,
		MDirection::Types	worldSys,
		double	angle = 0
	)

World Constructor.

x, y, and angle must both be 1) using the same world system as defined by worldSystem, and 2) in unit RegionShape::UNIT. Angle is counterclockwise, and the base is the east vector.

RSText::RSText	(	double	x,
		double	y,
		const String &	text,
		double	angle = 0
	)

Pixel Constructor.

Angle is counterclockwise.
