You CAN export an image from the applet, but you have to have the right
browser. (Does not work in MSIE.) That is, it is not a general solution
for the general user, but any web page developer can certainly take
"snapshots" of the model for use in other applications. This was
discussed earlier on this list, but I can't access the list archives
right now.
The command from the console or via JavaScript is
getproperty image
The result is a base-64 encoded JPEG image that looks like this:
/9j/4AAQSkZJRgABAAAAAQABAAD//gBBSl...
Pop that into an <img> tag using Firefox or Opera (not MSIE), and you
have an image that you can copy into your clipboard and do anything you
would do with a JPG. The JavaScript required to create the tag looks
like this:
var image = jmolGetPropertyAsString("image")
document.getElementById("someDiv").innerHTML ='<img
src="data:image/jpeg;base64,'+image+'">'
This is implemented in
<http://www.stolaf.edu/academics/chemapps/jmol/docs/examples-11/new.htm>.
Just under the applet, click on the word "image" or the word "stereo".
The stereo image can be generated by:
var width = 350
var height = 350
var s = '<table cellpadding="0" cellspacing="0"><tr>'
+'<td><img width="WIDTH" height="HEIGHT"
src="data:image/jpeg;base64,IMAGE"></td>'
+'<td><img width="WIDTH" height="HEIGHT"
src="data:image/jpeg;base64,IMAGE"></td>'
+'</tr></table>'
s.replace(/WIDTH/g,width)
s.replace(/HEIGHT/g,height)
var angle = 2.5
jmolScriptWait("rotate y " + (-angle))
s = s.replace(/IMAGE/,jmolGetPropertyAsString("image"))
jmolScriptWait("rotate y "+ (2 * angle))
s = s.replace(/IMAGE/,jmolGetPropertyAsString("image"))
jmolScriptWait("rotate y " + (-angle))
document.getElementById("someDiv").innerHTML =s
In that web page this sort of code is run within a pop-up window that is
running the jmol.js commands on the applet in the opener page. So you
will see "opener." in front of all the jmol commands. Those pop-ups are
getimage.htm and getstereo.htm in that directory.
