#include <itkImageIORegion.h>

Detailed Description

An ImageIORegion represents a structured region of data.

ImageIORegion is an class that represents some structured portion or piece of an Image. The ImageIORegion is represented with an index and a size in each of the n-dimensions of the image. (The index is the corner of the image, the size is the lengths of the image in each of the topological directions.) ImageIORegion is not templated over dimension, but uses dynamic arrays instead.

The first pixel of an image always have a Zero index. Therefore the index values of ImageIORegion may not directly correspond to those of ImageRegion. When translation between the two is performed one much consider the largest possible region who has a non-zero starting index for the image.

Constructor & Destructor Documentation

◆ ImageIORegion() [1/4]

itk::ImageIORegion::ImageIORegion ( unsigned int dimension )

Constructor. ImageIORegion is a lightweight object that is not reference counted, so the constructor is public.

◆ ImageIORegion() [2/4]

itk::ImageIORegion::ImageIORegion ( )

default

Constructor. ImageIORegion is a lightweight object that is not reference counted, so the constructor is public. Default dimension is 2.

◆ ~ImageIORegion()

itk::ImageIORegion::~ImageIORegion ( )

override

Destructor. ImageIORegion is a lightweight object that is not reference counted, so the destructor is public.

◆ ImageIORegion() [3/4]

itk::ImageIORegion::ImageIORegion ( const Self & )

default

Copy constructor. ImageIORegion is a lightweight object that is not reference counted, so the copy constructor is public.

◆ ImageIORegion() [4/4]

itk::ImageIORegion::ImageIORegion ( Self && )

default

Move-constructor. Fast and non-throwing.
