Detailed Description

template<unsigned int VDimension>
class itk::SlowPolyLineParametricPath< VDimension >

Represent a path of line segments through ND Space.

This class is intended to represent parametric paths through an image, where the paths are composed of line segments. Each line segment traverses one unit of input. A classic application of this class is the representation of contours in 2D images, especially when the contours only need to be approximately correct. Another use of a path is to guide the movement of an iterator through an image.

virtual OffsetType itk::SlowPolyLineParametricPath< VDimension >::IncrementInput ( InputType &  input ) const

virtual

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 bounds checking.

This is a fairly slow, iterative algorithm that numerically converges to the next index along the path, in a vertex-connected (8-connected in 2D) fashion. When possible, children of this class should overload this function with something more efficient.

WARNING: This default implementation REQUIRES that the ND endpoint of the path be either unique or coincident only with the startpoint, since it uses the endpoint as a stopping condition.
