XQuery/XSL-FO Images

Motivation
You want to enrich your documents with print quality images and charts etc.

Method
We will use the fo:external-graphic primitive.

For example, to add an external image add a block to the XSL-FO:

execute

Vector Images
SVG is a standard way to describe graphical artwork as vectors. Recent eXist installations (>1.4) with the Apache FOP processor enabled can embed SVG data in the resulting PDF as vector art: just reference them via http redirection as they are not in the file system. See ../Generating PDF from XSL-FO files/ on how to activate the XSLFO feature.

  

PDF image extension
For the daring: there is an extension to apache fop, that provides for pdf-images: a method of placing pages of PDF files in the FOP output. Its the work of Jeremias Märki and available at his webspace.

$ wget http://www.jeremias-maerki.ch/download/fop/pdf-images/fop-pdf-images-2.0.0.SNAPSHOT-bin.tar.gz $ tar xfz fop-pdf-images-2.0.0.SNAPSHOT-bin.tar.gz $ cp fop-pdf-images-2.0.0.SNAPSHOT/*jar EXIST_HOME/lib/user

I had to restart exist to activate pdf-images support in fop. The fo syntax is the same as with SVG, a page-number can be specified after a hash sign in the URL.
