[vtkusers] vtkConnectivityFilter --> source code

[Michnay Balázs]

Dear Goodwin Lawlor and other VTK users,
Thanks for the quick reply. Here's the source code which might be 
helpful to see what's going wrong...
The code is very simple, which might be the reason of it being out of 
function.

void CAnalyzeItView::OnConnectivityfilter() 
{
// TODO: Add your command handler code here

CAnalyzeItDoc* pDoc = GetDocument();

//m_idataThresh is a binary vtkImageData, it's a result of a 
vtkImageThreshold
pDoc->m_connectivity->SetInput(pDoc->m_idataThresh);
//Do I need this?
pDoc->m_connectivity->ScalarConnectivityOff();
pDoc->m_connectivity->ColorRegionsOn();
pDoc->m_connectivity->SetExtractionModeToAllRegions();
pDoc->m_connectivity->Update();

//This always returns 1:
AfxMessageBox(pDoc->m_connectivity->GetExtractionModeAsString());	
}

I'm sure I'm not setting important member variables and might not be 
calling the right methods, I'm a bit puzzled...

If I need this to get connected regions extracted from which I can build 
a volume, please post a sample C++ code how to do it or if I don't 
need this to get the volume built please give me some hints (source 
codes would be extremely helpful).
Goodwin Lawlor, thanks for your tips I'll look into those.

Thanks for your help in advance, I really appreciate it,

All the best,

 MB
