Re: Ways to output image to standard out

NCL is not versatile with stdin and stout. Believe me, I have tried.
How about just using a temp file and doing what is needed in the
shell? Untested pseudo code:

setenv TEMPNAME image.$PID.png
ncl prog.ncl >& /dev/null
   wks = gsn_open_wks("png","$TEMPNAME")
cat $TEMPNAME # this line puts PNG contents to stout
rm $TEMPNAME
