I don't usually stir the turd and I have to admit that I while I may
disagree on certain points, I respect the direction that RSI has taken IDL.
My mistake was to assume that since support for reading HDF5 files was added
in 5.6, that writing support would be soon to follow.

I have looked into this, and I also looked into the Java versions in hopes
of using the IDL->Java bridge but the former would be a project unto itself
and the latter approach is plagued by a lack of documentation/examples on
the IDL side.


Have you considered implementing your own home grown anti-aliasing routines
to smooth out those direct graphics fonts (if it is in fact the jaggies that
you despise). I posted some example code a while back...


Thanks for the info.
