[PyMOL] transparent background

[Douglas Kojetin]

Hi All-

Is it possible to create an image in PyMOL with a transparent 
background (without having to feed it through a second program, such as 
the ImageMagick suite)?

rant:  MS PowerPoint has the ability to make images transparent, 
however Apple's Keynote does not -- a missing feature that's likely to 
make me switch back from switching (presentation software; I'm not 
giving up OS X).

Thanks,
Doug
