[vtkusers] Saving BMP without visualizing them

[Dmitri Danewitz]

Hello!
 
I wrote a program, that visualizes a BMP and then saves it afterwards. But I can't manage to only save the BMP without visualizing it first. What am I doing wrong?
 
Here's how I try to save the vtkRenderer, where my image data is:
 
vtkRendererSource *renSrcBMP = vtkRendererSource::New(); 
  renSrcBMP->SetInput(ren[1]); 
  renSrcBMP->WholeWindowOn(); 
  vtkBMPWriter *bmpWriter = vtkBMPWriter::New(); 
  bmpWriter->SetInput(renSrcBMP->GetOutput()); 
  bmpWriter->SetFileName("d:/Output.bmp"); 
  bmpWriter->Write();
