Terry, That's very interesting. I just tried your code and it works great, I compared it to the XPDF method as well as our the manual thumbnailing we've been using (embarassingly) for a few years[0]. The colors in the PDF I used as an example are a bit exaggerated, but it's not too bad and the thumbnail is much more crisp.
BTW, I made a pull request[1] on your repo to add some installation / configuration instructions to your README.md. Cheers!
