I think it's a bug in Debian, we switched on prior=1 for batch files
(see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560412) which
appears to have been ill-advised.

If I add prior=0 to your script, it duly crashes with an out-of-memory
error while trying to render 4000x2325 here - if I half your output
image, I get a png, but it seems to be empty...

[PyMOL] PyMOL 1.7.2 on Ubuntu 15.04

2015-06-13 Thread Brenton Horne
Hi,

In response to an error I reported here about POV-Ray rendering giving
blank PNGs I decided to get rid of my source installation of PyMOL 1.7.6
and go with the 1.7.2 version found in the Ubuntu repository. So I ran this
script:

set ray_opaque_background, 1
png Trimethoprim_img0003.png, dpi=500, ray=1, width = 4000, height = 2325

to render a structure of Trimethoprim I had loaded. While the rendering was
somewhat better than that generated on 1.7.6, as it wasn't blank, it was
far from perfect as the output image Trimethoprim_img0003.png was 1146px by
668px in size, not the 4000px by 2325px I specified in this script. Anyone
know of any difference in 1.7.2 that would explain this besides a bug in
the Deb package available for Ubuntu?
