Embedding a Company Logo

The following procedure explains how to embed a company logo image in the front matter of the book for the DITA Map PDF - based on XSL-FO transformation scenario.

Create a customization directory (if you have not already done so).
Create a cfg\common\artwork directory structure in your customization directory and copy your logo to that directory (for example, [C:\Customization\common\artwork\logo.png).
Important: Make sure that your logo image is named: logo.png.
Rename Customization\catalog.xml.orig to: Customization\catalog.xml.

Open the catalog.xml in Oxygen XML Developer and uncomment this line:

  <!--uri name="cfg:fo/xsl/custom.xsl" uri="fo/xsl/custom.xsl"/-->

It now looks like this:

<uri name="cfg:fo/xsl/custom.xsl" uri="fo/xsl/custom.xsl"/>

Rename the file Customization\fo\xsl\custom.xsl.orig to: C:\Customization\fo\xsl\custom.xsl

Open the custom.xsl file in Oxygen XML Developer and create the template called createFrontCoverContents for DITA-OT 4.1.2.

Tip: You can copy the same template from DITA-OT-DIR\plugins\org.dita.pdf2\xsl\fo\front-matter.xsl and modify it in whatever way necessary to achieve your specific goal. This new template in the custom.xsl file will override the same template from DITA-OT-DIR\plugins\org.dita.pdf2\xsl\fo\front-matter.xsl.

Example:

For example, the custom.xsl could look like this:

<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:fo="http://www.w3.org/1999/XSL/Format"
    version="2.0">
  
<xsl:template name="createFrontCoverContents">
 <!-- set the title -->
 <fo:block xsl:use-attribute-sets="__frontmatter__title">
  <xsl:choose>
   <xsl:when test="$map/*[contains(@class,' topic/title ')][1]">
    <xsl:apply-templates select="$map/*[contains(@class,' topic/title ')][1]"/>
      </xsl:when>
      <xsl:when test="$map//*[contains(@class,' bookmap/mainbooktitle ')][1]">
        <xsl:apply-templates select="$map//*[contains
                                       (@class,' bookmap/mainbooktitle ')][1]"/>
      </xsl:when>
      <xsl:when test="//*[contains(@class, ' map/map ')]/@title">
        <xsl:value-of select="//*[contains(@class, ' map/map ')]/@title"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="/descendant::*[contains
           (@class, ' topic/topic ')][1]/*[contains(@class, ' topic/title ')]"/>
   </xsl:otherwise>
  </xsl:choose>
 </fo:block>
    
 <!-- set the subtitle -->
 <xsl:apply-templates select="$map//*[contains
                                          (@class,' bookmap/booktitlealt ')]"/>
 <fo:block xsl:use-attribute-sets="__frontmatter__owner">
  <xsl:apply-templates select="$map//*[contains(@class,' bookmap/bookmeta ')]"/>
 </fo:block>
  
 <!-- Load the image logo -->
  <fo:block text-align="center" width="100%">
   <fo:external-graphic
      src="url({concat($artworkPrefix, 
                          'Customization/OpenTopic/common/artwork/logo.png')})"
    />
  </fo:block>
 </xsl:template>

</xsl:stylesheet>

Edit the DITA Map PDF - based on XSL-FO transformation scenario, go to the Parameters tab, and set the customization.dir parameter to point to the location of your customization directory.
