[vtkusers] Help with vtkJPEGWriter and PostScriptWriter

[Dlwh at aol.com]

I'm having trouble with the vtk Image Writers...

Here's the code i'm attempting now...

  vtkJPEGWriter * Writer; 
      // = vtkJPEGWriter::New() doesn't work
      // Says it's undefined
    Writer->SetFileName(output_filename);
    Writer->SetInput(vtkImageData::SafeDownCast(data) );
    Writer->Write();
Here is the error i get:

scatter_main.o(.text+0xdde): undefined reference to vtkImageWriter::SetFileName(char const*)'  

I am including the ImageWriter headers (among others) yet it says that it's undefined, am i missing something?

Thanks,
David Hall
