I was intending to help with the development, but unfortunately a change to the business environment that I am in has meant that I don't think I will have the chance. > > In addition, the ability to say where the added postscript > code is to go > > would be useful. e.g. first thing in the page vs. last > thing in the page. > > Are you talking about adding PostScript code for OMR marks or other > marks to control the packaging process? Yes, identifying each page, in case the machine that careful places our perfectly rendered pages into envelopes, decides to practice modular origami. We run FOP multiple times, and in parallel, then join together all the output postscript files as desired. In doing so we insert separation pages, change page numbering based on plexing of output printed from various printers, add OMR, etc. Of use to us here would be the ability to identify resources (fonts and images) used in the documents, inserting short postscript macros to reference them during rendering, merging the lists of used resources from the parallel runs, then produce a single postscript header defining all the resources, with the names already used in the rendered documents. Obviously this is way beyond the scope of XSL-FO. FOP could possibly extend the FormattingResults to include lists of which fonts were actually used, and which images were used. I know that this could be determined by parsing the input FO, but I'm addicted to making code fast, and don't like doing things twice when once is sufficient. One requirement (that I am pleased to see you continuing) is the very high degree of similarity between PDF output and postscript output. Obviously the font handling code has a large impact here. A recent problem we have had is with the differing environment that Batik runs in when rendering for PDF and for postscript, specifically the identification of font resources that should be used, and why the PDF renderer starting asking for the Dialog font-family. Anyway, this is getting off topic, sorry. Stephen Denne.
