[vtkusers] vtkImageData from a DLL

[Dženan Zukić]

You may be compiling the dll and the app using different compiler settings,
such as threading model and/or debug mode. You should check that first.
Also different compiler versions (VS2008 and VS2010) use different runtime
libraries, so that might be mixed up too.

> MyDllClass* myDllObj = new MyDllClass();
> myDllObj->readImage();
> myDllObj->doProcessing();
>
> myViewer->SetInput( mydllObj->getOutput()) // no problem
>
>
> vtkImageData* result  = NULL;
>
> result = myViewer->GetInput();
>
> // result is still NULL
>
>
> It works fine if I include this function in my application, i.e. if I
> allocate the memory for this object within my application.
>
> I would be happy if someone could point out what the problem might be.
