That's exactly it. I have had problems installing cairo correctly on the Mac, so I think the easiest solution is to install aggdraw on your mac: - Download a distribution here: https://bitbucket.org/2degrees/aggdraw-64bits/downloads/aggdraw-1.1-64bits.tar.gz - extract the tarball somewhere - edit setup.py and set FREETYPE_ROOT to "/usr/X11" - set CFLAGS by runnig: export CFLAGS="-arch x86_64 -fpermissive" - build the package: python setup.py build - install the package: python setup.py install after you do this, the rdkit rendering should automatically use aggdraw and the quality should be a lot higher. I hope this helps, -greg ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
