Synopsis

WlzBSplineDistance [-h]  -d<dst> [-e<tol>] [-s <x>,<y>[,<z>]] [-t <ref>]
                   [<in object>]

Options

-h	Help, prints usage message.
-d	Distance from reference parametric coordinate (required).
-e	Tolerance for distances (default 0.01).
-s	Step size (default 1.0,1.0,1.0).
-t	Reference parametric coordinate along the B-spline curve (default 0.0).

Description: Computes the parametric coordinate at a given distance from a reference parametric coordinate. The step size may be used to compute the spline distances for non-unit pixel/poxel sizes. The parametric coordinate is written as a floating point number to the standard output. By default the input object is read from stdin.

Example

WlzBSplineDistance -d 20.0 spline.wlz

Prints out the parametric coordinate at the distance 20.0 from the start of the B-spline read from the file spline.wlz to the standard output.
