[PyMOL] Generating stereo figures using contrib.stpng()

[Peter H. <pet...@mo...>]

Hi Warren,

i have just updated the stpng() function that generates stereo figures. the 
function can be called with

contrib.stpng('filename.ext')

it supports a wide range of image formats, which are chosen by the extension 
of the image file (ie. .png .tif .ps .pdf .gif .jpg etc...).

contrib.stpng() requires the Python Image Library (PIL) to merge the left and 
right images, but the last part of the code can be commented out on systems 
that dont have PIL installed. in that case left and right images are still 
generated 'filename_left.png, filename_right.png', but not merged.

the function has been tested with the binary version of pymol_0.78 rh7.2 and 
python2.1 on a Linux system (SuSE7.3) .

The function is installed by replacing pymol/modules/pymol/contrib.py with 
the attached file and please ensure that PIL (ie. 
/usr/lib/python/site-packages/PIL) is included in your python path. 


cheers

peter
