Subject: Re: [docbook-apps] Adding a border around a DocBook <imageobject> in PDF output
Indeed, there is not an attribute-set for mediaobject
itself. I suspect that because there are so many attributes on the
graphics elements that must be supported, that another attribute-set might
introduce complicated interactions.
Fortunately, there is an easy way to get a border. Any
time you want to add features outside of an element itself, you can use
xsl:apply-imports. Try this:
<xsl:template match="mediaobject">
<fo:block border="0.5pt solid black"> <xsl:apply-imports/> </fo:block> </xsl:template> This will add a fo:block container with a border, and put the
image inside it. Unless you have already customized the template matching
on mediaobject, the apply-imports will fall back to the original DocBook
template for it.

Subject: [docbook-apps] Adding a border around a DocBook
<imageobject> in PDF output I have some screenshots to include as part of a user manual I'm compiling
with DocBook, and several are on white backgrounds and contain mainly text, so
doesn't mix well with other text layout on the page. I tried to find out
how to add a border by regarding DocBook XSL documentation, specifically:
..and the best I could do was following the second link, add a border
around the <figure> element (so it not only goes around the image, but
also around the <title>, leaving a lot of whitespace around the
image).
I then tried working out how add borders using the first link instead, so
that I'd only outline the image itself, but none
of <mediaobject>, <imageobject>, or <imagedata>
appear in the list of elements that recognize the attribute-sets referred to
there. A little further on, it says "you will want to find out where the
outer fo:block is output..." but I don't know what I'm looking for based on that
advice, nor how to find it, nor what to do with it (I'm a bit worried that I
might accidentally clobber something too by matching the template in a
higher-precedence customization layer).
Thanks, Christopher |
