Synopsis

WlzBSplineLength [-h]  [-s <x>,<y>[,<z>]] [-t [<min>],[<max>]] [<in object>]

Options

-h	Help, prints usage message.
-s	Step size (default 1.0,1.0,1.0).
-t	Parametric range along the B-spline curve (default 0,1).

Description: Computes the length of a path along a spline's curve between a pair of parametric coordinates. The step size may be used to compute the spline length for non-unit pixel/poxel sizes. The length is written as a floating point number to the standard output. By default the input object is read from stdin.

Example

WlzBSplineLength spline.wlz

Prints out the length of the B-spline read from the file spline.wlz to the standard output.
