[vtkusers] Bug in vtkBMPReader ?

[Steve Boyd]

Hi,

It seems to me that the method SetFileNameSliceOffset() is not working
properly.  As an example, I want to read in the following series of
bmps:

  Al300.bmp
  Al301.bmp
  ...
  Al310.bmp

  I set extent to [1,256,1,256,300,310] and then run the following code
snippet:

  vtkBMPReader *bmps = vtkBMPReader::New();
    bmps->SetFilePrefix(filename);
    bmps->SetFileNameSliceOffset(300);
    bmps->SetFileNameSliceSpacing(1);
    bmps->SetFilePattern("%s%.3d.bmp");
    bmps->SetDataExtent(extent);
    bmps->SetDataSpacing(el_size_mm);
    bmps->Allow8BitBMPOn();

  As a check that the file name was properly arranged with
SetFilePattern(), I do a check:

    bmps->ComputeInternalFileName(300);
    cout << "filename: " << bmps->GetInternalFileName() << endl;

  The output of this in my command window is:

  >> filename: D:\Al600.bmp 

  Something is work as I think it should read "D:\Al300.bmp", no?

Thanks,

Steve
