Hi Jeremias, I am quite interested in this feature and just tried it out. Seems to work for a lot of cases, but I ran into an issue which I guess might interest you.
If I attempt to render <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";> <fo:layout-master-set> <fo:simple-page-master master-name="Page" page-width="25cm" page-height="30cm"> <fo:region-body region-name="Body" /> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="Page"> <fo:flow flow-name="Body"> <fo:block> <fo:external-graphic src="../Temp_PDF_in_PDF/src/documentation/content/xdocs/dev/svg/images.pdf" /> </fo:block> </fo:flow> </fo:page-sequence> </fo:root> Where the images.pdf is the images.pdf that one finds after building fop, the resulting pdf seems to be corrupt. Enjoy your vacation, or, more likely, I hope you enjoyed your vacation, Thanks, Peter > -----Original Message----- > From: Jeremias Maerki [mailto:[EMAIL PROTECTED] > Sent: Monday, August 06, 2007 5:06 PM > To: [email protected] > Subject: PDF in PDF (experimental) > > As you will have seen, I've uploaded some changes into a temporary > branch.
