Re: idt&ncgm_to_png

Dear Ryoko Oda,

It sounds like you built NCAR Graphics from source, but it may not
have built "ictrans". As for your characters not appearing, this is
probably because in a PS file, you are plotting on a white background,
but the characters are still white.

What I recommend is going straight to a PS file, rather than an NCGM
and then a PS file. Try this:

   ncargex -W ps cpex08

This should create a file "cpex08.ps" file that has the black
background and white text.

If you want to keep using an NCGM, then you can swap the black
background and white foreground with this:

   ctrans -d ps.color cpex08.ncgm | pswhite > cpex08.ps

This way you will be able to see the characters, and, you won't
get that black box, which can be undesirable for output like
white paper.
