Bob has set up a new interface between the data model and the Jmol renderer, which allows him to define other types of export too. One of this is a POV-Ray export, which allows creating of high quality images for paper. Jmol has had POV-Ray export for a long time now, but never included the secondary structures or other more recent visual featues. PyMOL is well-known for its POV-Ray feature, and often used to create publication quality protein prints. The script command to create a POV-Ray input file takes the output image size as parameters:

write povray 400 600   # width 400, height 600

Here’s a screenshot of a protein with surface:

And here a MO of water:

Note the shading. More examples are available here.
