[vtkusers] how to save loaded image slices into a matrix.

[Dongqing Chen]

Dear All:

   Some code patches are listed below. 

    Now the volume is loaded into the memory, how can save it to a 3D matrix? I can not find the member function to finish this task either from vtkPNMReader or vtkImageReader2 class.

// Load  Segmented Volume
    readerSegmented = vtkPNMReader::New();
    readerSegmented->SetDataExtent(0, N1-1, 0, N2-1, 1, m_Slices);
    readerSegmented->SetDataSpacing(m_X, m_Y, m_Z);
    readerSegmented->SetFilePrefix (SourcePath);
    readerSegmented->SetFilePattern("%s.%03d.pgm");   

where: N1 is the width, and N2 is the height for each slice. 

  I want to save all the loaded segmented volume into, say: SegVolume[N1][N2][m_Slices].

Best Wishes,
