Detailed Description

template<unsigned int VDimension = 2>
class itk::Size< VDimension >

Represent the size (bounds) of a n-dimensional image.

Size is a class to represent multi-dimensional array bounds, templated over the dimension. Insight assumes that the first element of Size is the fastest moving index.

For the sake of efficiency, Size does not define a default constructor, a copy constructor, or an operator=. We rely on the compiler to provide efficient bitwise copies.

Size is an "aggregate" class. Its data is public (m_Size) allowing for fast and convenient instantiations/assignments.

The following syntax for assigning a size is allowed/suggested: Size<3> size = {256, 256, 20};
