Martin,
I can't remember if you mean
(a) "restore from a few minutes ago within this session" or
(b) "restore from a previous session using data saved on the server"
So I will use this opportunity to discuss different ways to save the state,
some of which are very new and only a couple of us are aware of.
(a) "restore from a few minutes ago within this session"
This is trivial. All within Jmol. This works for all versions of Jmol:
:
save state xxx
restore state xxx
(b) "restore from a previous session using data saved on the server" and
using 12.3:
Option 1. Slicker-than-ice new method
WITHIN Jmol we will post the entire state to the server, including all
necessary files to restore the state, in PNGJ format. That is, Jmol
basically does its own AJAX to deliver a PNGJ file to its server. You can
do this with the signed or unsigned applet. The load command is used so
that we can confirm that the upload was successful.
print load("myserverurl.xxxx/xxxx?POST?_PNGJ_")
That is really the slickest way to go, because you get an image that you
can check. You have to have a server-side app that can accept a post. The
variable will be server POST variable will be "_PNGJ_" and it's value will
be a base64-encoded image. Server should return something like "OK". If
this is your interest, talk with me, because I just realized we could
easily just send the entire state in binary format and make this one step
simpler. I like this option because on the server you get an image that
can be delivered straight back to a client either as an image or as a Jmol
model. This option is Jmol 12.3.30-only. Use the files in
http://chemapps.stolaf.edu/jmol/Jmol-12.zip
Option 2: Just the state to server, no files:
If you know the files are always available (remote or from your site) and
you do not want to save a full PNGJ state, you can just use this to save
the Jmol state script:
print load("myserverurl/saveJmolState.php?POST?state=" +
getProperty("stateInfo"))
For either of these options you would have to figure out how to restore the
state from your server using something like this within Jmol:
script "myserverurl/restoreJmolState.php?....."
and have the server either return the state script or the PNGJ file.
