Constructor & Destructor Documentation

BRotatedRect	(	const BRect &	rBounds,
		const double	dAngle,
		const double	dHeight
	)

Constructs a BRotatedRect and calculates the four points associated with the rectangle's corners.

This routine assumes that the rectangle has been rotated around its upper-left corner.

Parameters:

	rBounds	The minimum bounding rectangle for the rotated rectangle.
	dAngle	The angle by which the rectangle has been rotated, in radians.
	dHeight	The length of the side of the rotated rectangle connecting the upper-left corner to the lower-left corner.
