Functions
WlzGreyValueWSpace *	WlzGreyValueMakeWSp (WlzObject *obj, WlzErrorNum *dstErrNum)
	Creates a grey value work space from the given object. The resulting grey value work space should be freed using WlzGreyValueFreeWSp(). More...
void	WlzGreyValueFreeWSp (WlzGreyValueWSpace *gVWSp)
	Free's the given grey value work space created by WlzGreyValueMakeWSp(). More...
void	WlzGreyValueGet (WlzGreyValueWSpace *gVWSp, double plane, double line, double kol)
	Gets a single grey value/pointer for the given point from the object with which the given work space was initialised. When the object has a non-scalar value table then only the first value will be returned, however when the value is not background all values can be accessed via the grey pointer. More...
void	WlzGreyValueGetCon (WlzGreyValueWSpace *gVWSp, double plane, double line, double kol)
	Gets the four/eight connected grey values/pointers for the given point which lie at: More...
WlzGreyType	WlzGreyValueGetGreyType (WlzGreyValueWSpace *gVWSp, WlzErrorNum *dstErr)
	Access function to get the object's grey type. More...
int	WlzGreyValueGetI (WlzGreyValueWSpace *gVWSp, double plane, double line, double kol)
	Gets a single grey value for the given point from the object with which the given work space was initialised. More...
double	WlzGreyValueGetD (WlzGreyValueWSpace *gVWSp, double plane, double line, double kol)
	Gets a single grey value for the given point from the object with which the given work space was initialised. More...
void	WlzGreyValueGetDir (WlzGreyValueWSpace *gVWSp, int plane, int line, int kol)
	Gets a single grey value/pointer for the given point from the 3D values and domain in the work space. More...
