Detailed Description

template<unsigned int VImageDimension>
class itk::ImageRegion< VImageDimension >

An image region represents a structured region of data.

ImageRegion is an class that represents some structured portion or piece of an Image. The ImageRegion 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.)

template<unsigned int VImageDimension>
itk::ImageRegion< VImageDimension >::~ImageRegion ( )
default

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

◆ ImageRegion() [2/4]
