[vtkusers] Screenshots

[Pan, Tony C (Research)]

JPEG uses lossy compression, so quality degradation should be expected.  You can try one of the other
image formats, like BMP, PNM, or TIFF.  PNG format is lossy, but it might give you better quality
than JPEG.

Hi all
I'm using 

	vtkWindowToImageFilter* l_w2if= vtkWindowToImageFilter::New();
	l_w2if->SetInput(RenderWindow);
	
	vtkJPEGWriter* l_wr= vtkJPEGWriter::New();
	l_wr->SetInput(l_w2if->GetOutput());
         l_wr->SetQuality(100);
	l_wr->SetFileName("screenshot.jpg");
	l_wr->Write();

to do screenshots. However, the quality is not as good as the image rendered on the screen. Any help
or ideas would be highly appreciated.

Gregi
