Detailed Description

Defines lower and upper valid indices.

Is part of the basic characteristic of each Data instance. Encapsulates a start and end index. Size and Dimension are directly extracted from Extent.

Constructor & Destructor Documentation

Extent() [1/6]

Extent

(

)

default constructor

Extent() [2/6]

Extent

(

const Extent &

r

)

copy constructor

Extent() [3/6]

Extent	(	const Point &	p1,
		const Point &	p2
	)

initialize with start and end point

Extent() [4/6]

Extent

(

const Size &

s

)

initialize with Size

The extent will go from -(size-1)/2 to (size-1)/2 for odd sizes, and from -(size/2-1) to size/2 for even images

not explicit on purpose, facilitates easier creation code

Extent() [5/6]

Extent	(	const Size &	size,
		const Point &	center
	)

initialize with center point and size

Extent() [6/6]

Extent	(	const Point &	start,
		const Size &	size
	)

initialize with Size and start point
