Yes...
I built a Java display program about 5 years ago to view the
ntrans files- with remote access. The code set was pretty easy 
to replicate- so I can look at the zooming issue.

The Nmeta files are in raw coordinates from 0 to 32767, but 
since the lines & text are vector (like postscript), zooming
would be a reasonable option. The advantage to postscript 
is that the PS driver supports image display, where the NC
driver does not.
