[Vv] small vv bug

[Joel Schaerer]

Hi all,

I lost quite some time today because vv does not warn the user when it
doesn't find the raw file attached to an mhd. Instead, it displays garbage.

The function that needs to be fixed is probably vvImageReader::Update.
Unfortunately, I don't know ITK well enough to know immediately what
needs to be done. Any ideas?

itk::ImageIOFactory::CreateImageIO(mInputFilenames[0].c_str(),

  if (!reader) {
    mLastError="Unable to read file.";
  } else {
    reader->SetFileName(mInputFilenames[0]);
    reader->ReadImageInformation();
    if (mInputFilenames.size() > 1)
     
Update(reader->GetNumberOfDimensions()+1,reader->GetComponentTypeAsString(reader->GetComponentType()),type);
    else
     
Update(reader->GetNumberOfDimensions(),reader->GetComponentTypeAsString(reader->GetComponentType()),type);
  }
}
