[Jmol-users] Jmol applet printing

[Robert H. <ha...@st...>]

I was noticing that the applet is blank when printing a page. From what I
can tell, it's a serious issue for all applets, and may not have an easy
solution. but here's a slick way to do it in Firefox, as demonstrated at
http://chemapps.stolaf.edu/jmol/docs/examples-11/jmol-flot.htm


1) Create two divs, one for an image and one for the applet:

<div id="imagediv" class="printonly"></div>
<div class="noprint">
<script type="text/javascript">
jmolInitialize(".","JmolAppletSigned0.jar")
jmolApplet(["450","450"],....)
</script>
</div>

2) Now for styles we have:

<style>
@media print {
    .noprint {display:none}
    .printonly {display:block}
}
@media screen {
    .noprint {display:block}
    .printonly {display:none}
}
</style>

And to get the image we use a link on the page that runs this JavaScript
function.

function setImage() {
    document.getElementById("imagediv").innerHTML = '<img
src="data:image/jpeg;base64,'+jmolGetPropertyAsString("image")+'" />'
}

Now when the page is printed, the image is created and displayed, and the
applet is hidden. It appears that the applet has printed.

By the way, that base64 image business is broken in Jmol 11.7 -- only fixed
in the next release, 11.7.35.
Works like a charm, but only for Firefox, not Opera or MSIE.
