[u liu]

hi,my dear vtkusers,
    i am a newbie in the vtk,recently i had a question.
  the idea:
            i draw a  polygon myself ,the size is 380*261;the format is BMP.
                the name of picture is named like this 
                   yu01.bmp,yu02.bmp............
               the picture is exsit in the E:\bmp1\,
            now  i want to read it and  reconstruction.
  the code :
            vtkBMPReader *v8=vtkBMPReader::New();
          v8->SetFilePrefix("E:\\bmp1\\yu");
         v8->SetFilePattern("%s%2d.bmp");
        v8->SetDataExtent(0,379,0,260,1,13);
        v8->SetDataSpacing(1,1,1);
        v8->Update();
         vtkPolyDataMapper *ctmapper=vtkPolyDataMapper::New();
       ctmapper->SetInputConnection(v8->GetOutputPort());
      vtkActor *ctactor=vtkActor::New();
     ctactor->SetMapper(ctmapper);
     vtkRenderer *ctren=vtkRenderer::New();
     ctren->AddActor(ctactor);
    ctren->SetBackground(0.1,0.1,0.1);
    vtkRenderWindow *ctrenwin=vtkRenderWindow::New();
   ctrenwin->AddRenderer(ctren);
      ctrenwin->Delete();
   ctren->Delete();
 ctactor->Delete();
ctmapper->Delete ();
v8->Delete();
   
  the error:  
  ERROR: In ..\..\VTK\IO\vtkBMPReader.cxx, line 95
vtkBMPReader (017D6E70): Unable to open file E:\bmp1\yu 1.bmp
