[vtkusers] about the BMP slices Read & 3D Rendering

[#YAN RI AN#]

Dear VTK-Users:
I also met the same problem when I read a stack of 512x512x256 *.BMP head slice files.(33 slices)
The XY boundary size of the files is 220.2mm X 220.2mm. 
Actually the images are grayscale 8 bit CT  Head Slices.
I wanted to read the stack of slices and 3D Reconstruction.
Could you share some vtk source code about the process of  tiff and jpeg Slices.
I thinked we met the similar problem.
there is my source code:
  vtkImageReader *reader=vtkImageReader::New();
  reader->SetFilePrefix("g:/00head/head/h");
  reader->SetDataByteOrderToLittleEndian();
  reader->SetDataExtent(0,63,0,63,1,33);//
   reader->SetDataSpacing(1,1,1);
  reader->SetDataMask(0x7ff);

    vtkMarchingContourFilter *iso=vtkMarchingContourFilter::New();
    iso->SetInput(reader->GetOutput());
    iso->SetValue(0,255);//Scalar between 0~255 in 8 Bits.

  vtkPolyDataMapper *isoMapper=vtkPolyDataMapper::New();
  isoMapper->SetInput(iso->GetOutput());
  isoMapper->ScalarVisibilityOff();
