Hi,
If the image viewer itself is interpolating and you don't want this,
then I recommend
you use the -s option to generate a scaled up version of the image
(with many image
pixels per original voxel) as that should make it look better. Also
make sure you use
the -n option to avoid interpolation by slicer itself.
As for the edges, that is very strange if you have only specified a
single input image
file. You should run a command like:
slicer inputimage -s 4 -u -a outputimagefilename
Note that -a, and not -A, gives you just three views.
If you are still having trouble with this then please send us the
exact command
that you are running.
All the best,
Mark
