Re: [Jmol-users] sending a screen shot back to a server.

Paul,

I mean that any applet can send back its view as PNG or PNGJ to the server.
Very simple creation of images, at the size of the applet, at least. Just
have the applet send it back! It is encoded base64, so you need to decode
that at the other end. I had problems with PHP because it also decoded the
+ as <space> and I had to manually replace those with + again:

    $info = base64_decode(str_replace(" ", "+",
$_REQUEST["?POST?_PNG_"].$_REQUEST["?POST?_PNGJ_"].$_REQUEST[_PNG_].$_REQUEST[_PNGJ_]));
    echo file_put_contents($imagefile, $info);

If nature does not answer first what we want,
it is better to take what answer we get.
