Detailed Description

template<long N = 2>
struct Euclid::Fits::Region< N >

A n-D rectangle region, defined by its front and back positions (both inclusive), or front position and shape.

Like Position, this class stores no pixel values, but coordinates.

Static Public Member Functions
static Region< N >	fromShape (Position< N > frontPosition, Position< N > shape)
	Create a region from a front position and shape.
static Region< N >	whole ()
	Create an unlimited region. More...

Public Member Functions
long	dimension () const
	Get the number of dimensions.
Position< N >	shape () const
	Compute the region shape.
long	size () const
	Compute the region size, i.e. number of pixels.

Public Attributes
Position< N >	back
	The back position in the region.
Position< N >	front
	The front position in the region.
