PDF Thumbnailing with Google App Engine (Python)

Is it possible, using the python version of google app engine, to create a thumbnail of a PDF file?

The goal is for the user to be able to upload a PDF, and开发者_开发技巧 see it represented as a thumbnail on the page.

You may be able to use Google's imaging services directly, since PDFs are essentially images and PIL can do this, though I haven't tried it.

If the direct approach doesn't work, you may be able to use the following process:

1. Save the PDF to the blobstore.
2. Open its link.
3. Obtain a snapshot of the displayed PDF using a service like http://www.websnapr.com/.
4. Save that generated image into your blobstore.

No. This requires a PDF renderer, and to the best of my knowledge no such thing exists in pure-Python. You'll have to use an external service to generate thumbnails.
