[vtkusers] Save images of a volume in 1: 1

[Jose Barreto]

I'm using a vtkVolume to display a DICOM volume.

How should I proceed to save the image generated by this vtkVolume ensuring
its size in 1: 1? And if possible with a dpi of 300?

I saw the way to save is to be ...

Void UCModulo3D::WindowToJPG(vtkRenderWindow * rw, const char * filename)
{
	vtkWindowToImageFilter * filter = vtkWindowToImageFilter::New();
	filter->SetInput(rw);	
	filter->Update();

	vtkSmartPointer<vtkMetaImageWriter> writer =
vtkSmartPointer<vtkMetaImageWriter>::New();
	writer->SetFileName(filename);
	writer->SetInputData(filter->GetOutput());
	writer->Write();
	writer->Delete();
	filter->Delete();
}

But in this way the size is taken into consideration the vtkrenderwindo
size.
