bug report: path omitted in rendering to pdf

23 Jun 2015


      Hi, all,
I'm a happy, long-time user of inkscape. Thanks for all your efforts over the years
on this wonderful open-source project.
This email is to report a bug in pdf rendering, which occurs in both the stable
version and, as shown below, in the version compiled from the latest sources.
$ /usr/local/bin/inkscape --version
Inkscape 0.91+devel r14210 (Jun 22 2015)
$ /usr/local/bin/inkscape --export-pdf=b.pdf b.svg
$ ls -l b.pdf
-rw-r--r-- 1 bcrowell bcrowell 857 Jun 23 05:42 b.pdf
The file b.svg, which I've pasted into this email below, contains a single object,
which is a moderately complex filled path. When I export to pdf, the resulting file
does not contain any rendering of the object (as you can see from its small size in
the listing above). Rendering to a bitmap works correctly, and rendering of filled
paths does normally work, of course. The bug seems to depend on something specific
about this particular path. I don't know whether this is a bug in inkscape or in
cairo. The version of cairo on my system appears to be 1.13.0, based on the existence
of this file:
  /var/cache/apt/archives/libcairo2_1.13.0~20140204-0ubuntu1.1_amd64.deb
Regards,
Ben
