pdf on the fly

hello *: I know that php has support for pdf built in, and I have taken a look at resources on phpbuilder and the PDFLib site...basically allowing you to create pdf documents on the fly...interesting, but not very compelling... Is anyone using pdf in some interesting php application? What I am really looking to find out if it is possible to have users upload docs (say, word, illustrator, wordperfect, pagemaker) and have the server convert them to pdf? Perhaps allow users to create pdf docs by gathering form info? any resources or links or ideas appreciated! Thanks Luis __________________________________________________ Do You Yahoo!? Yahoo!
