PDF management with PHP

If PDFlib or any other pdf generating component exists that can perform the following tasks. Any Idea?

PDF conversion / modification

We need the functionality to convert a PDF file to a) a PDF file with lower resolution, and b) a JPEG/PNG file for

previewing in the browser. We also need to be able to crop or resize a PDF file.



PDF preflight

Integrating some sort of PDF preflight that checks certain key aspects of a PDF file, such as font embedding, image resolution
etc.

Impositioning
Create a hi-resolution PDF file with the size of the printing press and step up the artwork automatically. This
should include a calculator that guarantees maximum usage of the space using landscape or portrait tiles or
a combination of both.

PDFLib can do that, but you need to by the additional PDO section. I don't really think there is a way to edit a PDF other than that method. You may be able to do some funky stuff with printing to a JPG printer or a PDF printer & sending resizing parameters to that.
