[vtkusers] Texture Mapping Image Quality

[Patrick Lowry]

To All:

The texture mapping capabilities of VTK are amazing but I noticed image 
quality loss from the original TIFF.  Texture mapping done by a commercial 
program I have does not suffer the same quality loss.  The essence of the 
image part of the TCL script are shown below.  Any ideas on preventing 
image quality loss?

Thanks in advance.
