Re: [PyMOL] Getting a dashed line through a transparent surface

Hi John,

There's a limit to what PyMOL can do by itself, but it sounds like
composition might be the easiest approach.  First, render the image
without the dashed line:

ray

save background.png

Then, disable everything but the dashed line and then render it alone
with opaque_background disabled:

unset opaque_background

ray

save foreground.png

Then combine the two images externally using something like GIMP,
Photoshop, or even PowerPoint.

cheers,
Warren
