We don't have a quick reference for the scripting api yet - I'm hoping
that is something that will be put together in the next few months.
Are you using Jalview's command line mode for writing PNG files ? (I
presume so - if not see
http://www.jalview.org/help/html/features/clarguments.html ) - in which
case, you can specify 1, 2 (sort of), 3, 4 and 5 via a properties file
(see the format menu for the options).
The missing features as far as I can see is that there's no option for
setting the number of columns in wrap mode, and species ordering is not
something that Jalview can do automatically - but you could do it using
a 'sort by annotation', 'sort by features' or 'sort by tree' operation
after loading annotation onto the alignment, but there might be one or
two snags that need straightening out.
Contact me off list with an example alignment and properties file and
I'll take a look.
