Hi,
I'm using OpenBabel 2.3.2 on Mac (installed via homebrew) and on Ubuntu 12.04
(compiled from github tag 2.3.2 with cmake options -DRUN_SWIG=ON and
-DPYTHON_BINDINGS=ON). In both these cases I'm having problems with the png
format(s) from Python. The command line obabel (obabel -:c1ccncc1 -ismi -O
test.png --gen2D) is working great, but when I'm trying to do the same from
pybel there are some problems…
To start with, png2 is not in pybel.outputformats so mol.draw() won't work at
all. If I try to use mol.write("png", "test.png") instead I get a Segmentation
Fault. Finally, through the openbabel module in python
conv.SetInAndOutFormats("smi", "png") yields a string
('\x00\x00\x00\x11tEXtsmiles\x00c1cnccc1\t\n\xce\x88`\x8b') that I suppose is
what would be included in the png created by the png2format and using
conv.SetInAndOutFormats("smi", "png2") returns False, I suppose due to the fact
that png2 can't be loaded.
Any ideas on what can have gone wrong?
Kind regards,
Fredrik
