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.

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

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 198 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.
