[Insight-users] Grafting a C++ array onto a VectorImage filter output

[Ramón Casero Cañas]

Hi all,

Grafting a C++ array (in this case from Matlab) onto a normal 128x128 
image is
quite straightforward. First we allocate memory for the array


   mxArray *p = (mxArray *)mxCreateNumericArray(ndim,
					  dims,
					  mxUINT8_CLASS,
					  mxREAL);

Later we get a pointer to this array

   // pointer to the Matlab output buffer
   uint8_T *imOutp =  (uint8_T *)mxGetData(p);

and graft it onto the ITK filter output

   const bool filterWillDeleteTheBuffer = false;
   this->filter->GetOutput(0)->GetPixelContainer()
      ->SetImportPointer(imOutp,
   	       128*128,
   	       filterWillDeleteTheBuffer);


But how can this be done if the output of the filter is a VectorImage, 
e.g. the third output of the DanielssonDistanceMapImageFilter?

Best regards,

Ramon.
