Re: FOP Interfaces
Hi Jeremias, and all other peoples here, I would like to know where an arbitrary event has occured during fop rendering. Let me give you a short example: i produce a *big* pdf with fop that should include another pdf that was produced in another way (i my case, it was produced by distiller from a word document). That document should be included after a fo:table.../fo:table that is somewhere inside my document. Second example : i want to watermark some specific pages according to the content that is on these pages. For that purpose, i use iText. So what i want is some kind of mechanism (for exemple something like fox:page-number id=myId/) that would enable me to get an Hashtable that contains the page where this event has occured. After getting this hashtable, i could run iText-based process to finish my pdf. Is that more clear? Excuse me for my not-that-good-english, i have also to admit that it was not that clear in my head. Thanks, Fred. --- Jeremias Maerki [EMAIL PROTECTED] a écrit : Do you just want to know how many pages were rendered (See Driver.getResults().getPageCount()) or do you want to insert PDF pages of your own while FOP is rendering? Or something else, because I think I don't undertand, yet, what you want? I would *love* to be able to be able to get the page number where some event append (for example by stating fox:page-number/ in .fo source) cause it would greatly improve fop/itext interfacing. I personnaly use fop to render most of my content but i finish the work using itext (to watermark content, reorganize pages to produce booklets, insert some annexes written in pdf .. etc) Thanks a lot, whether you implement that or not!

I get it now, thanks. I think that's an interesting thing. Definitely, worth putting on the task list. I could use something like that, too.

Make sure your concept allows resolving those pesky url(#stuff) properties in embedded SVGs generated by a transformation, which may mean baseURI is not constant, or that you need more than one baseURI. AFAIK Batik doesn't provide for user supplied URI resolving code either, so it's probably necessary to talk to them. I want to note that several code pieces for resolving URLs and/or file locations are scattered all over FOP and Batik. Replacing them all with an URIResolver invocation would unify behaviour and remove redundancies. I'd also recommend to lift the default URIResolver implementation from Saxon, it seems to tolerate the usual abuse better than everything else i came across elsewere. Keep up the good work!

Eeeek! (Sorry!) For these two I've already added a couple of classes you can get that information from. I've added this just for completeness. Have a look at org.apache.fop.apps.FormattingResults and the Driver.getResults() method. My original post can be found here: http://marc.theaimsgroup.com/?l=fop-devm=100747811203665w=2 page-master used for each page (could be used to control the paper bin to get paper from, important for me in conjunction with PS Renderer). During rendering or after the rendering is complete? Both. The PSRenderer could use it during rendering so it can set the respective paper bins. Currently, I'd need it more after rendering is complete because I currently generate PDFs that get converted to PostScript later on and I patch those files afterwards to apply paper bin selection (and other stuff).

Re: FOP Interfaces
Since this seems to be a hot topic at the moment I thought I might jump in. To use FOP in the various contexts we need to properly setup the right interfaces. First we need to determine why and what those interfaces are. All of the interfaces are set through the Driver. The Driver is the central control point for all fo - pdf etc. transformations. I'm not so sure right now, if a monolithic Driver class is so good. Maybe we really have a little number of specialized classes for FOP processing that are particularly easy to use. For example an easy one that integrates nicely with JAXP. That could help reducing the support questions on how to embed FOP. Maybe we can have a FOPResult (similar to SAXResult) that people can use. I don't know yet, I'm just trying to gather some thoughts. :-) Below is a sample of the type of areas and information that needst o pass to and from FOP: User agent The list of things this needs to supply is on this page, rather badly formatted: http://xml.apache.org/fop/design/useragent.html Logging - logging level - logging messages of various levels - error handling XML input - various ways to supply FOP with the xsl:fo file - sax handler general options - base directory - uri resolvers renderer options - embedding fonts - compression in pdf - image embedding for the PS renderer (eventually): - PostScript Level - PPD to use - binary/ascii switch FOP's component setup: which implementation of a particular LayoutManager to use, Logging setup (LogKit, Log4J, JDK14Logging), etc. Output from FOP: - Generation statistics: Number of pages total, Number of pages of each page-sequence, page-master used for each page (could be used to control the paper bin to get paper from, important for me in conjunction with PS Renderer). The Driver handles the XML input. The user agent information is through the FOUserAgent. We could handle logging through the user agent. Options could also be handled through the user agent, using mime type selection for renderer options. May I add that it might be nice if we could render to more than one renderer at once (maybe not from the command line). Two independent sources have asked me in the last few weeks if this works. I must say that this would be nice, since I could generate a PDF for the archive and the PS for the printer in one run. It would probably be faster than converting the PDF to PostScript afterwards. So, what do people think. What other information will be needed. Maybe there's more...
