Hi Zhao,

Check the bit-depth of the BMP.  Try loading an 8 or 24-bit BMP.

Hi,all
    I  am a new user of VTK. The enviroment is MSVC + VTK+ ITK for
win2000.
    In MSVC, I write the following code:

    vtkBMPReader* reader = vtkBMPReader::New();
    reader->SetFileName(BMP file path);
    vtkImageViewer* viewer = vtkImageViewer::New();
    viewer->SetInput(reader->GetOutput());
    viewer->SetSize(256,256);
    viewer->Render();

  After executing,it show a black window,not display image. why?
  can someone tell me the reason and how to corect it?
Thank u!!


Regards,
