The XML catalog file is used when a file is
actually opened for use. In the case of graphics in XSL-FO output, the DocBook
stylesheet does not open the graphic files, the XSL-FO processor does. So
you need to configure your XSL-FO processor to use your catalog
file. There is a similar issue for resolving the DTD reference that
is in some SVG files. There is a short example in my book for setting
up a catalog in XEP, but it would be similar for FOP.

Subject: [docbook-apps] Using draft
images with fop, and catalogs.
I am using Saxon
and FOP to generate PDF files from DocBook. And I'm using a draft
image.
My customized
stylesheet for DocBook->FO includes a value for the parameter
draft.watermark.image. It is currently the full
local path to the draft.png file that I am using (ie somethiing
like C:/DocBook/docbook-xsl-1.74.0/images/draft.png)
I would like to
change it to be a url (or is it a uri), probably using the catalog resolving
mechanism that is available in Saxon using the -x, -y, -r, -u
qualifiers.
I notice that at
the moment the filename value appears in the FO file in the form
"url(images/drft.png)" when I set draft.watermark.image to "images/draft.png"
in my custom xsl file. Thus I presume that the stylesheet is just
copying over the parameter value and putting it in
"url()".
Can someone advise
how to go about doing this. Do I need to tell the XSL stylesheet to
change the format of what it inserts in the FO ? Or do I need to tell
FOP that it's a URL/URI and to use the resolver ?
Uncertainly,
Richard.
