I had some code which I wrote a while back against IDL 6.0 which would
save an object graphics view to an EPS file. Everything worked just
fine with 6.0. Now when I run the same code with IDL 6.1, I see the
following errors.
% Program caused arithmetic error: Floating underflow
% Program caused arithmetic error: Floating illegal operand
These errors are only present when I use the /VECTOR flag on the
IDLgrClipboard -> Draw command. Of course, I can leave off /VECTOR and
everything works fine, but that's a less than ideal solution since part
of the reason of using EPS was to take advantage of the vector format
(much smaller, much cleaner). Besides the errors, the EPS file created
with /VECTOR is corrupt. When I try to open the EPS with GhostScript, I
see the following error.
Error: /undefined in nan
I haven't yet confirmed what is causing the problem, but it may be
related to the text I'm using. I have been able to successfully create
EPS files of axes and plot data, but without text. As soon as text gets
added, it seems that the arithmetic errors start showing up the the EPS
files become corrupt.
I'll do some more tests to see if I can determine what it is that causes
this problem, but in the meantime, has anyone else seen this or
experienced anything like it? I can't find anything in RSI's techtips
-- the closest was a techtip about corrupt PS files in direct graphics.
