[Matplotlib-users] Problem generating postscript
Hi again
regarding my last post, I still have pb generating simple eps files.
Now I turned on usetex to True and I get the message given below. If
anyone can help me with this, it would be great since I am now stuck
with this.
Reminder: the pb occurs when I save a figure (savefig) in postscript
format (.eps), after plotting a number of small thumbnail images (using
pcolormesh and contour).
cheers
Eric

Re: [Matplotlib-users] Problem generating postscript
This is a kind of bug that is quite hard to trace unless we can
reproduce the error.
As far as I know, there has been a report that matplotlib does not
work well with GPL Ghostscript 8.63. And I'm not sure if it is
related.
http://old.nabble.com/Segmentation-fault-with-EPS-output-on-matplotlib-%3D0.98.5.2-to25257581.html#a25334270
So, see if using xpdf as a distiller works.
Regards,
-JJ

Hi thanks a lot for the quick tip. But no xpdf does not do it (I had tried it). Just to be consistent below is an account of my config (may not help much).
