Hello,
right now I'm trying to modify the pdf-export for adding attached
pdf-files to the end of the export like the existing functionality for
adding attached images.
Starting from the beginning with the pdf.vm I couldn't find an analogy
to include the pdf-files in the way of image-files, because as I see it
the images just get rendered as html.
Can anybody give me a hint how to proceed to solve this task?
Hm, that's a very difficult topic... I don't think it's possible out of
the box, but here are some ideas:
Apache FOP, the tool we use for generating PDFs, doesn't support
embedding external PDF documents in the output by default, but there is
a FOP extension that adds support for this:
http://www.jeremias-maerki.ch/development/fop/index.html
This extension provides support for:
<fox:external-document src="my-doc.pdf"/>
This means that you would have to change the way we generate the FO
document by:
- adding <img src="$doc.getAttachmentURL('file.pdf')"/> in pdf.vm
- changing the way img tags are processed in xhtml2fo.xsl so that it
generates fox:external-document instead of fo:external-graphic if the
image ends with .pdf
Another option is to post-process the PDF generated so that you combine
it with the attached PDF files using pdfbox, but that would require some
Java code to extend the PDFExportImpl class to add this behavior.
