Functions
WlzErrorNum	WlzMeshFreeTransform (WlzMeshTransform *mesh)
	Free's the given mesh transform. More...

WlzMeshTransform *	WlzMeshTransformNew (unsigned int nNode, unsigned int nElem, WlzErrorNum *dstErr)
	Creates a mesh transform data structure with the nodes, elements and displacements allocated and initialized to zero. More...

WlzMeshTransform *	WlzMeshTransformAdapt (WlzMeshTransform gMesh, double minArea, WlzErrorNum dstErr)
	Adapts the given mesh transform so that each of the elements in the displaced mesh has an area greater than the given minimum. More...

WlzMeshTransform *	WlzMeshTransformCopy (WlzMeshTransform gMesh, WlzErrorNum dstErr)
	Copies the given mesh transform. The copied mesh will have any zombie elements squeezed out. More...

WlzMeshTransform *	WlzMeshFromObj (WlzObject srcObj, WlzMeshGenMethod method, double minDist, double maxDist, WlzErrorNum dstErr)
	Creates a mesh transform for the given object with all mesh displacements zero. More...

WlzObject *	WlzMeshTransformObj (WlzObject srcObj, WlzMeshTransform gMesh, WlzInterpolationType interp, WlzErrorNum *dstErr)
	Transforms a woolz object using a the given mesh transform. More...

WlzMeshTransform *	WlzMeshTransformFromCPts (WlzObject obj, WlzFnType basisFnType, int polyOrder, int nSPts, WlzDVertex2 sPts, int nDPts, WlzDVertex2 dPts, WlzMeshGenMethod meshGenMtd, double meshMinDist, double meshMaxDist, WlzErrorNum dstErr)
	Computes a mesh transform for the given object and a set of control points using both an affine and a basis function transform to set the mesh displacements. More...

WlzErrorNum	WlzMeshAffineProduct (WlzMeshTransform mTr, WlzAffineTransform aTr, int order)
	Computes the product of the given affine and mesh transforms in place, ie the mesh transform has it's displacements overwritten. More...

WlzErrorNum	WlzMeshTransformVerify (WlzMeshTransform mesh, int dispFlg, int badElm, WlzMeshError *dstErrMsk)
	Checks that the given mesh transform is valid. More...

double	WlzClassValCon4 (double *g, double p, double q)
	Interpolate pixel value using maximum probability. More...

WlzMeshTransform *	WlzMeshFromObjBox (WlzObject srcObj, WlzIBox2 dstBox, int boxDilation, WlzErrorNum *dstErr)
	Creates a mesh transform for the given object where the mesh has just two elements which enclose the objects bounding box. All mesh displacements are zero. More...

WlzDVertex2	WlzMeshTransformVtx (WlzDVertex2 vtx, WlzMeshTransform mesh, WlzErrorNum dstErr)
	Transform the vertex using the given mesh transform. More...
