> # splitting files (e.g. remove no longer needed resources) Each page has its own Resources dictionary, so it shouldn't be too difficult. One thing to watch out for is is the "page tree" which allows pages to inherit resources from each other, this is handled as PDPageNode but it's kind of messy.
> # merging files (e.g. avoid duplicating resources) Sounds like the files are pretty similar, is this actually an overlay? Or are you wanting to insert entire pages? I imagine you probably want to implement both these features at the COS level rather than the PD level, as it's pretty low-level processing. -- John > On 29 May 2014, at 00:39, Maruan Sahyoun <sahy...@fileaffairs.de> wrote: > > Hi, > > for a current project I need to work on enhancing PDFBox for > > # splitting files (e.g. remove no longer needed resources) > # merging files (e.g. avoid duplicating resources) > # page handling (adding/removing individual pages with resource handling) > # enhancements to forms handling (pre fill XFA forms - partially done, > enhancing AP generation) > > Is someone else working on something similar? > > BR > > Maruan
