[vtkusers] vtkImageViewer's

[Mathieu Malaterre]

May I suggest you reread the FAQ:
http://catb.org/~esr/faqs/smart-questions.html#prune

Thanks.

As for your question vtkImageViewer and vtkImageViewer2 from a user
point of view are very different object. vtkImageViewer will display
2D images (glDrawPixels), while vtkImageViewer2 will display texture.
There basically no reason to use vtkImageViewer IMHO, since texture on
any hardware accelerate card will be just as fast (if not faster) as
glDrawPixels.

In GDCM, I chose to use vtkImageViewer2, since vtkImageViewer would
not handle Spacing of my images. However there is a slight issue with
Window Level implementation in vtkImageViewer2, so I had to create
this vtkImageColorViewer. I believe there is post in vtk-dev which
explains why I could not directly 'fix' vtkImageViewer2.
