Very nice. On a Mac (10.8.3) with Safari (6.0.2) the generated image is
automatically opened in Preview and when dropped onto Jmol.jar reveals the true
Jmol content.
Firefox, Chrome and Opera work too prompting to open the new file.
The resolution of the image is presumably based on the size of the JSmol
window, which is small in Bob's demonstration page, and so the final resolution
is low. I've used similar image generation methods from very large applets in
the past to create higher quality graphics.
Is there a way of changing the dimensions of the JSmol applet on the fly or by
getting it to track the size of the window? As in
http://chemapps.stolaf.edu/jmol/docs/examples-12/new.htm - new resizable window?
Best regards
Nick

Note the new link "image" under the applet at
http://chemapps.stolaf.edu/jmol/jsmol/jsmol.htm
The PNG image is constructed in JavaScript, encoded as BASE64, and sent to
the server for decoding and sending back as a PNG file. In this case, it's
a PNGJ file, so it serves both as an image and a ZIP file containing the
relevant files. (At least, 7Zip opens it as a ZIP file and MSPaint opens it
as an image). I think you can also use other methods with HTML5 to capture
the image from a canvas, but I'm not sure that works with all browsers.
