Resources are usually reused by different pages. Sometimes content is stored as a resource (XObjects). Sometimes all the content of a page is stored in a resource. Also: some information about a page stream isn't referred to from the /Resources dictionary of a page, but it's stored elsewhere, e.g. in an outline tree, in a structure tree,... At first sight, the question looks like a requirement from somebody who doesn't understand what PDF is about. Or like a requirement from somebody who is trying to reinvent PDF/VT. You'll have to explain WHY you need to decompose the PDF documents and then later compose them based on the different parts. iText offers you low level functionality to rip any PDF apart and it has methods that allow you to stitch a PDF together using different objects. However: it's something you should avoid if you don't know ISO-32000-1 back to back. ------------------------------------------------------------------------------ DreamFactory - Open Source REST & JSON Services for HTML5 & Native Apps OAuth, Users, Roles, SQL, NoSQL, BLOB Storage and External API Access Free app hosting.
