Inheritance diagram for itk::Path< TInput, TOutput, VDimension >: Collaboration diagram for itk::Path< TInput, TOutput, VDimension >:Represent a path through ND Space.
This base class is intended to represent a path through an image. As a path, it maps a 1D parameter (such as time or arc length, etc) to an index (or possibly an offset or a point) in ND space. This mapping is done via the abstract Evaluate() method, which must be overridden in all instantiable subclasses. The only geometric requirement for a gerneral path is that it be continuous. A path may be open or closed, and may cross itself several times. A classic application of this class is the representation of contours in 2D images using chaincodes or freeman codes. Another use of a path is to guide the movement of an iterator through an image.
| TInput | Type of the 1D parameter of the path, e.g. unsigned int or double. |
| TOutput | Type of the path location at the given input, e.g. itk::Offset< VDimension > or itk::ContinuousIndex< VDimension > |
| VDimension | Dimension of the path. |

Where does the path end (what is the last valid input value)? This value is sometimes used by IncrementInput() to go to the end of a path.
Reimplemented in itk::OrthogonallyCorrected2DParametricPath, itk::PolyLineParametricPath< VDimension >, itk::HilbertPath< TIndexValue, VDimension >, itk::ChainCodePath< VDimension >, and itk::ChainCodePath< 2 >.

Evaluate the path at specified location along the path. Return data is the path's "natural" format.
Implemented in itk::ChainCodePath< VDimension >, and itk::ChainCodePath< 2 >.

Like Evaluate(), except always returns an index

Run-time type information (and related methods).

Increment the input variable passed by reference such that the ND index of the path moves to its next vertex-connected (8-connected in 2D) neighbor. Return the Index-space offset of the path from its prior input to its new input. If the path is unable to increment, input is not changed and an offset of Zero is returned. Children are not required to implement general bounds checking, but are required to return an offset of zero when trying to increment from the final valid input value.
Implemented in itk::ChainCodePath< VDimension >, and itk::ChainCodePath< 2 >.

Where does the path begin? For most types of paths, the path will begin at zero. This value can be overridden in children, and is necessary for iterators to know how to go to the beginning of a path.
