Detailed Description

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

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

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

For efficiency sake, 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 convienent instantiations/assignments.

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

template<unsigned int VDimension = 2>
void itk::Size< VDimension >::Fill (  SizeValueType    value )  [inline]
 

Set one value for the index in all dimensions. Useful for initializing an offset to zero.

Definition at line 184 of file itkSize.h.

template<unsigned int VDimension = 2>
SizeValueType itk::Size< VDimension >::GetElement (  unsigned long    element )  const [inline]

Member Data Documentation

template<unsigned int VDimension = 2>
SizeValueType itk::Size< VDimension >::m_Size[VDimension]
 

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}};

The doubled braces {{ and }} are required to prevent `gcc -Wall' (and perhaps other compilers) from complaining about a partly bracketed initializer.
