RE: The apparently unsolvable issue.. Duplex Page Numbering Support
Thanks Andreas, Turns out by changing the PDF library used to edit the PDFs to a commercial one (PDFNet) provides greater speed .. so I may just have to deal with that until the standard evolves that little bit further ;-) Thanks for the help -Original Message- From: Andreas Delmelle [mailto:[EMAIL PROTECTED] Sent: Friday, 30 May 2008 6:46 AM To: fop-users@xmlgraphics.apache.org Subject: Re: The apparently unsolvable issue..

The apparently unsolvable issue.. Duplex Page Numbering Support
I've had to remove the FO file as I can only assume that's why I'm hitting the spam threshold.. perhaps the apache mailing lists are a little anal? -Original Message- From: Martin Edge [mailto:[EMAIL PROTECTED] Sent: Thursday, 29 May 2008 2:03 PM To: 'fop-users@xmlgraphics.apache.org' Subject: The apparently unsolvable issue.. Duplex Page Numbering Support Hi, I have done a reasonable amount of digging across the internet but I am unable to find any workaround possible. Hopefully the answer isn't you're just stuck. I am using XSL-FO to format physical letters. The XSLT /XSL-FO template incorporates multiple postable letters in a single XSL-FO document. I use block ids to find out my current page sequences and numbers.. such as: fo:page-number-citation ref-id=startofsection1/-fo:page-number-citation ref-id=endofsection1/ fo:page-number-citation ref-id=startofsection2/-fo:page-number-citation ref-id=endofsection2/ And so on. Some of these letters however, may be printed in duplex mode when it hits our printer.

The page number in this case is used to generate a barcode which is printed on the front of a piece of paper which is read by a paper inserter. I have attached one of my FO files for your perusal.. I also notice Antenna XSL talks about MathML.. is that the sort of thing I'm looking for? Hope there is some magic out there somewhere!
