I’ve been working on a commercial project where we would have liked to use Ghostscript. To use ghostscript in a commercial settings (i.e. to distribute it alongside binary code) you need to have a license. At the time of writing (September 2014) – the costs for this are rather prohibitive:
There is a minimum $8000 per quarter and a $5000 set-up fee. This fee can increase depending your business usage.
Wow. That’s too rich for me. Time to find another pdf lib.
