docbook-apps

Hi guys,

I asked about a FOP problem on the fop-users list, but it turned out to
be not a FOP problem, but rather an issue with the DocBook style sheets,
thus bringing it up on this list.

The issue: When creating PDF, I get lots of warnings like this:

SEVERE: Image not found. URI: ../common/images/note.svg. ...

This is not severe at all (the PDF builds fine, no issues in the layout,
etc.), but the warnings clutter up the output, which makes it hard to
identify real issues like overflow problems.

So I created FO to see where note.svg would show up. Here's a relevant
snippet:

<fo:block><fo:external-graphic width="auto" height="auto"
content-width="36pt"
src="url(../common/images/note.svg)"/></fo:block></fo:list-item-label><fo:list-item-body

start-indent="body-start()"><fo:block space-before.minimum="0em"
space-before.optimum="0em" space-before.maximum="0em"
font-family="Helvetica,Verdana,Arial,Sans Serif" font-size="10pt"
font-weight="bold" margin-left="0.25in" margin-right="0.25in"
border-left="5pt solid black" padding-left="0.1in" hyphenate="false"
keep-with-next.within-column="always">Note</fo:block><fo:block
space-before.minimum="0em" space-before.optimum="0em"
space-before.maximum="0em" margin-left="0.25in" margin-right="0.25in"
border-left="5px solid black" padding-left="0.1in"><fo:block
space-before.optimum="1em" space-before.minimum="0.8em"
space-before.maximum="1.2em">
The logic of the previous example also applies for a
relation such as this one:

In DocBook, this would be:

<note>
<para>
The logic of the previous example also applies for a
relation such as this one:

So, quite apparently, note.svg is inserted for a DocBook <note>. (I've
confirmed for other instances of note.svg in the FO file.)

But when searching the DocBook XSL style sheets (local copy) for
note.svg, all I get is this:

2005-01-05 Jirka Kosek <kosek@users.sourceforge.net>

* caution.svg, important.svg, note.svg, tip.svg, warning.svg:
New file.

No clue as to how the file gets inserted into the FO. :-(

Searching e.g. the 1.77.1 DocBook XSL style sheets for note.svg gives me
this:

docbook-xsl-1.77.1/images/colorsvg/note.svg
docbook-xsl-1.77.1/images/note.svg

Still no clue why (and how) note.svg is referenced in the FO, but at
least it's an existing file, although FOP seems to expect it in a
different location (../common/images), thus the error.

This looks like a bug in the DocBook XSL style sheets to me, but maybe
it's not. In any case, how could I work around this issue, so that the
warnings won't show up any more? (I could probably copy note.svg and
friends to a ../common/images/ folder for each of our docs, but I'd
rather avoid that.)

Thanks in advance for any pointers!

Cheers,

Stefan
