Re: [docbook-apps] Image callouts and roles

Hi  Chris,

OK.  Prior to Docbook 5, imageobjectco only allowed one imageobject, so that is the case that the stylesheet currently handles.  I did not realize that more  than one was allowed in DocBook 5, so that will need  to get fixed in the stylesheets. I filed a bug report.

 

For now, the selection process applies only to the direct children of mediaobject.  That's why you are getting both images in your output.  You'll need to create two children of mediaobject for the selection to work.

Hi Chris,

Rendering two images side-by-side in FO output is not expected behavior.  The selection process takes into account all the allowed objects:

 

<xsl:template name="select.mediaobject.index">
  <xsl:param name="olist"
             select="imageobject|imageobjectco
                     |videoobject|audioobject|textobject"/>

   ...

 

You say you got both the .svg and the .png image in your FO output?  I copied and pasted your example into a test file and processed it with the stock 1.76.1 stylesheet and I got just the .svg image.

 

Sorry, I was trying several different things and screwed up my test case. The following includes both images when transformed to FO with the stock 1.76.1 fo/docbook.xsl stylesheet:

    <screenshot>
      <mediaobject>
    <imageobjectco>
      <areaspec>
        <area coords="500,500,600,600" xml:id="example-co"/>
      </areaspec>
      <imageobject role="fo">
        <imagedata fileref="/path/to/MVC-DIT-structure.svg"/>
      </imageobject>
      <imageobject role="html">
        <imagedata fileref="/path/to/MVC-DIT-structure.png"/>
      </imageobject>
    </imageobjectco>
      </mediaobject>
    </screenshot>

That is, one imageobjectco containing two imageobjects that differ by role. My transformation is done using:

$ xsltproc --nonet --xinclude --stringparam xep.extensions 1 --output article.fo /path/to/docbook-xsl-1.76.1/fo/docbook.xsl article.xml

Cheers,

Chris
