[docbook-apps] Re: Shading columns with a background color

[Colin Shapiro]

My apologies, I had some typos in the code I posted.  Here it is again:

<xsl:param name="column.count" select="3"/>
<xsl:param name="column.gap" select="0.1in"/>
<xsl:param name="page.width" select="8.5in"/>

<xsl:variable name="column.gap.pt">
 <xsl:call-template name="length-in-points">
   <xsl:with-param name="length" select="$column.gap"/>
 </xsl:call-template>
</xsl:variable>
<xsl:variable name="page.width.pt">
 <xsl:call-template name="length-in-points">
   <xsl:with-param name="length" select="$page.width"/>
 </xsl:call-template>
</xsl:variable>

<xsl:variable name="column.width.pt">
 <xsl:value-of select="($page.width.pt -
                        (($column.count - 1) *
                          $column.gap.pt))
                       div $column.count"/>
</xsl:variable>

<xsl:template name="column.shading">
 <xsl:param name="column.number" select="1"/>

 <xsl:if test="$column.number &lt;= $column.count">
   <fo:block-container absolute-position="absolute"
                       background-color="gray"
                       height="100%"
                       width="{$column.width}pt">
     <xsl:attribute name="left">
       <xsl:value-of select="($column.number - 1) *
                             ($column.width.pt +
                              $column.gap.pt)"/>
       <xsl:text>pt</xsl:text>
     </xsl:attribute>
     <fo:block/>
   </fo:block-container>

   <xsl:call-template name="column.shading">
     <xsl:with-param name="column.number" select="$column.number + 1"/>
   </xsl:call-template>
 </xsl:if>
</xsl:template>
