Jmol 11.2 uses PNG compression 2 only Jmol 11.3 uses PNG compression 0 by default (that's a bug I will fix -- it is intended to be 2) but the -q switch intended for JPG quality is also setting PNG compression level. The acceptable range is 0 - 9, so it's just the wrong default value.
The command line switch -q should set this: -q 1 -q 2 -q 9 09/10/2007 09:28 PM 750,678 t.png # default 09/10/2007 09:28 PM 35,003 t0.png # -q0 09/10/2007 09:28 PM 36,268 t1.png # -q1 09/10/2007 09:27 PM 29,781 t9.png # -q9 So that appears to be working. All are gorgeous. Bob Michal Bozon wrote: >I have an additional question on this topic: non-interactively generated PNG >images are uncompressed.
