Hello,
I am using Matplotlib version 0.99.1.1.
I have a simple problem: when outputting to PDF or SVG, alpha blending
does not work for the lines drawn by "contour". However, alpha blending
does work for the regions given by "contourf".
Both work when outputting to PNG.
My Python script (and data file) and example output (PDF, SVG, PNG) are
posted here:

Thank you!
Regards,
Sourav

You are right, this is a real bug, verified in svn. Since the agg backend works correctly and the pdf and svg backends do not, it appears to be essentially a bug in those backends. I am calling this to Jouni's attention, since he is the pdf backend expert; but in case neither he nor anyone else can get to it right away, if you have not seen any other response within a day, please file a bug report on the tracker so this doesn't get lost. If you do so, please use a simple and completely self-contained script to illustrate the problem.
Thank you.
Eric
