Renders fonts horrendously like I haven't seen in 5+ years. Is this produced on Linux with FreeType? Looks like you don't have TrueType hinting enabled.
My first attempt didn't produce anything the first two minutes I waited. I assume it timed out. You may want to look into providing some kind of feedback if the queue is long, for example, so that I can adjust my expectations accordingly. (Although realistically, I'd never bother to use something that didn't produce an image within 5 seconds.)
Doesn't load external fonts from services like Google web fonts so it creates inaccurate screenshots for a lot of websites. An issue with QtWebkit, that is assuming this uses PhantomJS.
As for PhantomJS, I hadn't heard of it. I was originally rendering the screenshots with Selenium and the FirefoxDriver. They came out looking good, but performance was abysmal and when a page froze up I needed a mechanism to kill firefox manually.
Now I'm using Wordpress's Mshots service, but I'm looking at a couple of python tools to generate headless screenshots.
I just got it working with PhantomJS and I must agree it does look a lot better. The problem with external fonts is still there so I'll have to crack open QtWebkit to see if we can't fix that.
I have used it on two projects in the past and found it very easy to use, but incredibly powerful. If you check it out, try out one of the more recent RC builds as they contain functionality the stable release does not.
Yea, it's not quite polished just yet so you get the occasional failure to load a screenshot. I figured I'd gauge interest before dumping a bunch of time to clean up the edge cases.
