OK, I thought that might be too simple. 8^) If you want the border to match the image size, you'll need to put the border on the fo:external-graphic element. Unfortunately, that means you need to copy and customize the template named 'process.image' from fo/graphics.xsl. That is currently a large template that handles a lot of attributes. But adding your border attribute should be no problem.

However, to tweak it just a little more... I had set up my images to be 90% of page width, like this: <figure pgwide="1"> <title>some caption</title> <mediaobject role="screenshot"> <imageobject> <imagedata fileref="media/usrprf.export1.png" scalefit="1" align="center" width="90%"/> </imageobject> </mediaobject> </figure> ...and your suggested example draws the border full page width. I tried fiddling with the template, like this : <xsl:template match="mediaobject[@role='screenshot']"> <fo:block border="0.5pt solid black" width="90%"> <xsl:apply-imports/> </fo:block> </xsl:template> ...but the "90%" in the fo:block is apparently not used. So I have empty white borders either side, within the outline. I can of course make the images 100% wide but that scales them vertically too, using excessive paper area. Also, I'm a little uneasy about forcing 90% anyway on the template, I'd like it to stick to the image if possible. What solutions should I consider?

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.

I tried to find out how to add a border by regarding DocBook XSL documentation, specifically: - http://www.sagehill.net/docbookxsl/BordersAndShading.html - http://www.sagehill.net/docbookxsl/Graphics.html ..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
