You mean something like this?

    vtkPNGReader* reader = vtkPNGReader::New();
    reader->SetFileName("Test.png");
    reader->Update();

    vtkImageData* imagedata = reader->GetOutput();

    vtkXMLImageDataWriter* writer = vtkXMLImageDataWriter::New();
    writer->SetInput(imagedata);
    writer->SetFileName("Test.vti");
    writer->Update();

What I don't understand is how to actually load this resulting file in
Paraview. If I open it like I normally do vtp files, it opens in a separate
window rather than in the normal "model space" where everything else opens.
Anyone know how to open it as if it was a slice of a volume data set?

Thanks,

David
