问题
I'm trying to generate server-side images of a portion of my DOM, and then serve those images up to users from my server once they're created.
I'm curious as to the implementation possibilities of PhantomJS, as I don't entirely understand its purpose beyond exploring and testing. I get that it is a self-contained binary, and I've got it running basic apps like in their tutorials. But is there a way to do something along the lines of the following?
<html>
<body>
<h1>This is a test.</h1>
<button>Rasterize!</button>
</body>
<script>
$('button').click(function() {
// invoke PhantomJS here to generate PNG of this page
});
</script>
<html>
Specifically, I'm looking at doing something along the lines of:
phantomjs rasterize.js https://localhost:9999/test.html test.png
Someone, please, school me!
