Detailed Description

template<unsigned int VOffsetDimension = 2>
class itk::Offset< VOffsetDimension >

Represent the offset between two n-dimensional indexes in a n-dimensional image.

Offset is a templated class to represent a multi-dimensional offset, i.e. (i,j,k,...). Offset is templated over the dimension of the space.

Member Function Documentation

template<unsigned int VOffsetDimension = 2>
void itk::Offset< VOffsetDimension >::Fill (  OffsetValueType    value )  [inline]
 

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

Definition at line 160 of file itkOffset.h.

template<unsigned int VOffsetDimension>
Offset< VOffsetDimension > itk::Offset< VOffsetDimension >::GetBasisOffset (  unsigned int    dim )  [static]
 

Return a basis vector of the form [0, ..., 0, 1, 0, ... 0] where the "1" is positioned in the location specified by the parameter "dim". Valid values of "dim" are 0, ..., VOffsetDimension-1.

Member Data Documentation

template<unsigned int VOffsetDimension = 2>
OffsetValueType itk::Offset< VOffsetDimension >::m_Offset[VOffsetDimension]
 

Offset is an "aggregate" class. Its data is public (m_Offset) allowing for fast and convienent instantiations/assignments.

The following syntax for assigning an index is allowed/suggested: Offset<3> index = {5, 2, 7};
