Detailed Description

Stores the coordinates and the rotation of shapes in the plane.

This class stores coordinates in the plane and a rotation angle. Thus, it can be used to describe the position of shapes in the plane. Note that the members exponential() and logarithm() are similar but not exactly the same as in the class ShapeInterface.

Constructor & Destructor Documentation

imaging::Position2d::Position2d	(	const ublas::fixed_vector< float_t, 2 > &	center,
		float_t	rotation
	)

Constructs a Position2d object from center and rotation.

Member Function Documentation

void imaging::Position2d::assign	(	const ublas::fixed_vector< float_t, 2 > &	center,
		float_t	rotation
	)

Assigns center and rotation to the object.

const ublas::fixed_vector<float_t, 2>& imaging::Position2d::center

(

)

const [inline]

Returns the center of the position.

float_t imaging::Position2d::rotation

(

)

const [inline]

Returns the rotation of the position.

void imaging::Position2d::set_center

(

const ublas::fixed_vector< float_t, 2 > &

center

)

[inline]

Sets the center of the position.

void imaging::Position2d::set_rotation

(

float_t

rotation

)

[inline]

Sets the rotation of the position.

void imaging::Position2d::exponential	(	ublas::vector< float_t >::const_iterator &	vector,
		Position2d &	shape
	)			const

Computes the exponential of the data at the current position of the iterator vector and stores it in shape.

References _center, and _rotation.

void imaging::Position2d::logarithm	(	const Position2d &	shape,
		ublas::vector< float_t >::iterator &	vector
	)			const

Computes the logarithm of shape and stores it at the current position of the iterator vector.

References _center, and _rotation.

size_t imaging::Position2d::dimension

(

)

const [inline]

Returns the data dimension of a position, i.e. 3.
