I am currently developping for a client a wordpress CMS which will act as webservices for a windows phone application. In this CMS, I will use ImageMagick for PHP to convert a multipage PDF to a single image. This image will then be sent to windows phone application. The PDF will almost never changed and it is to make the operation transparent for admin of CMS. I want, when they change the PDF (which will be perhaps extremly rare), to make make it invisible for them.
My question is this : can we use GhostScript which will be used by ImageMagick without a commercial licence ?
I contacted Artifex but they weren't very helpful with their answers. They oriented me to another of theirs software. They didn't answer at all my questions.
Thanks
Tristan
