[vtkusers] something about image

[Chen Fu]

Hi!
I didn't have the vtk book in hand and not very clear
by reading the manual doxygened. So hope somebody
could solve my puzzle.
What's the difference between vtkImageViewer and
vtkImageViewer2? 
What's the meaning of ColorWindow/ColorLevel? why
255/127.5 pair will show the normal color we see in
other software?
Is there possible to use imagemagick with vtk to read
and write other image format?
Thank you!!
