[vtkusers] Reader object - reading extra information from a file.

[Chris Hughes]

Hi!

I have appended 3 UINTS to the beginning of my raw data, representing
the dimensions of the data. I have been using the reader object in the
following way to read the volume data, but I need to extend this so that
the reader reads the 3 UINTS first, before reading the raw data. Can
anyone point me in the right direction??

  vtkImageReader *reader = vtkImageReader::New();
  reader->SetFileName(fileName);
  reader->SetFileDimensionality(3);
  reader->SetDataExtent(0, xDims-1, 0, yDims-1, 0, zDims-1);
  reader->SetDataOrigin(0, 0, 0);
  reader->SetDataScalarTypeToUnsignedChar();
  reader->SetDataSpacing(xRes, yRes, zRes);
  reader->SetHeaderSize(0);

Thanks!

Chris
