[vtk-developers] RE: Wrapping GetBounds-like functions

[Ken Martin]

Hey Chris,

The function must have a signature such as:

float *GetSomething() or int *GetSomething() etc...

and be listed in VTK/Wrapping/hints, there are many examples in the
hints file to help you get the hang of it.

Thanks
Ken
