Re: [docbook-apps] Using draft images with fop, and catalogs.

["Bob Stayton" <bobs@sagehill.net>]

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.
