Functions
WlzObject *	WlzProfileLine (WlzObject *gObj, WlzIVertex3 sPos, WlzIVertex3 ePos, WlzErrorNum *dstErr)
	Creates a new 2D Woolz object with a single line which is the profile from the given start position to the given end position. Empty objects are allowed and in this case a new empty object is returned. In other cases (where there is no error) the returned object will always be a 2D spatial domain object (WLZ_2D_DOMAINOBJ) which has an interval domain and where the given object has values a rectangular value table. These will have a single line with the pixel at 0,0. When the line segment between the given points does not intersect the given object a spatial domain object is still returned but it will have no intervals and it may be necessary to call WlzIsEmpty().

WlzIntervalDomain *	WlzProfileLineIDom (WlzObject *gObj, WlzIVertex3 sPos, WlzIVertex3 ePos, WlzErrorNum *dstErr)
	Creates a new 2D Woolz interval domain with a single line which is the profile from the given start position to the given end position for the given spatial domain object. More...
