I make canned animations using ictrans -d xwd -resolution -e ' k plot' gmeta >frame.k
for k from 1 to desired frame mumber. THe xwd format is an x window dump
which can either be converted with gnu convert or (since I am not allowed
to use gnu stuff in operations .. site policy) the image can be read
directly from the frame.k file (read resolution size bytes backwards
from the end of the frame.k file). I then do optional manipulations
on the pixels (mode zero everything else 255 is a common one to prepare
for B&W fax generation) and save the results.
You can put the header for a raster format you are familiar with
onto the raw image and then display it or use xwdto$whatever in
gnu convert.
