You will need a PDF renderer. There are a few more or less good ones on the market (ICEPdf, pdfrenderer), but without, you will have to rely on external tools. The free PDF renderers also cannot render embedded fonts, and so will only be good for creating thumbnails (what you eventually want).

My favorite external tool is Ghostscript, which can convert PDFs to images with a single command line invocation.

This converts Postscript (and PDF?) files to bmp for us, just as a guide to modify for your needs (Know you need the env vars for gs to work!):

UPDATE: pdfbox is now able to embed fonts, so no need for Ghostscript anymore.

In Ghost4J library (http://ghost4j.sourceforge.net), since version 0.4.0 you can use a SimpleRenderer to do the job with few lines of code:

  1. Load PDF or PS file (use PSDocument class for that):

  2. Create the renderer

  3. Render

Then you can do what you want with your image objects, for example, you can write them as PNG like this:

Note: Ghost4J uses the native Ghostscript C API so you need to have a Ghostscript installed on your box.
