Nico, Jmol 11.3.38 is ready to go. It addresses all of Rolf's findings.
There are now three antialias settings:
antialiasDisplay TRUE/FALSE [default TRUE]
antialiasImages TRUE/FALSE [default FALSE]
antialiasTranslucent TRUE/FALSE [default FALSE]
The third applies to either images or the display. It cleans up
translucent objects. It has no effect unless antialiasDisplay or
antialiasImages is also set TRUE.
Memory requirements are significant, in multiples of (width) * (height)
32-bit integers:
antialias OFF ON-translucent ON+translucent
no translucent 2 8 8
objects
with translucent 4 10 16
objects
Note that no antialising at all is required for POV-Ray output. POV-Ray
will do antialiasing on its own.
Rolf -- really great testing there. The complex combination of text,
draw objects, translucency, POV-Ray, and image writing was just what I
needed. Please check again and see if it isn't all corrected. It's still
possible that the dialog won't work for you, but it does under Windows.
So you might want to do a little debugging yourself in PovraySaver.java
to see what is going wrong there if this persists. I note that in
Windows I get a warning that POV-Ray security doesn't like the loading
of files from any random directory. But it's a simple OK/CANCEL prompt.

please check; certainly working under Windows.

I had not considered translucent objects. Turns out this was a VERY
tricky fix. Originally we thought translucent objects wouldn't need
antialiasing, but my experimentation today suggests that they do. But
that requires substantially more memory allocation. So it's an option.

This was a nasty complex interaction of settings. Should be fixed. But
if not....
