Re: [matplotlib-devel] pdf output
This seems to be a cross platform bug and unrelated to fonts -- at least
I am able to reproduce it on Linux.
There was a small typo in the recently added support for non-rectangular
clip paths. Fixed in r3829.
(Jouni -- you may want to review this and verify that my change is correct.)
Cheers,
Mike

I used the following:

pylab.rc('pdf',compression=0)
plyab.plot([1,2,3],[1,2,3])
pylab.savefig('simple.pdf')
See attached.
Do you know what set of fonts are getting embedded? If their not in the
mpl set, it's possible they haven't been tested.
Should be the standard set, but I haven't verified.

Re: [matplotlib-devel] pdf output
I'm not sure yet how to fix the problem, but in the sample I sent
earlier if I change:
5 0 obj
/Length 11 0 R
endobj
to
5 0 obj
/Length 1239
endobj
then both gv and acroread can process the file without error.

Re: [matplotlib-devel] pdf output
Did r3829 not work for you? (Or did you miss that in my earlier post?) I don't think anything related to Lengths has changed recently, and it did work at one point...

Re: [matplotlib-devel] pdf output
Has anyone worked with postscript files on windows? I don't know if this is
related, but when I do a savefig('foo.ps',dpi=150) on plot generated by
pcolormesh, I find that ghostview gives the error:
DSC Error at line 518:
%%Page: 1 1
This %%Page: line occured in the trailer, which is not legal.
EPS files should be encapsulated in %%BeginDocument/%%EndDocument
It is possible that an EPS file was incorrectly encapsulated
and that we have been confused by the %%Trailer in an EPS file.
This was running with the latest version from SVN. I looked in the file and
could not find a BeginDocument error.
Thanks,
William
