Subject RE: How can I rotate text for a 90o sidebar?
Date Thu, 31 Mar 2005 15:52:29 GMT
I hadn't really looked at this because the huge indentations put me off, 
but now I've gotten around to it.

You can do this without disabling escape characters and by using literal 
result elements. I'm inserting the whole stylesheet because the named 
template needs to be called with certain parameters rather than just the 
string you want rendered in stacked blocks (though you could write a 
template that would take just the string). Here's the whole stylesheet 
(tested on Saxon 8):

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
  version="2.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:fo="http://www.w3.org/1999/XSL/Format"
  exclude-result-prefixes="fo">

  <xsl:template match="/">
    <xsl:call-template name="scatter-string">
      <xsl:with-param name="text" select="substring(.,2)"/>
      <xsl:with-param name="rotated"select="substring(.,1,1)"/>
    </xsl:call-template>
  </xsl:template>
 
  <xsl:template name="scatter-string">
    <xsl:param name="text"/>
    <xsl:param name="rotated"/>
    <fo:block><xsl:value-of select="$rotated"/></fo:block>
    <xsl:if test="string-length($text) > 0">
      <xsl:call-template name="scatter-string">
        <xsl:with-param name="text" select="substring($text, 2)"/>
        <xsl:with-param name="rotated" select="substring($text,1,1)"/>
      </xsl:call-template>
    </xsl:if>
  </xsl:template>

</xsl:stylesheet>

The only change to the algorithm is to wrap the block around the result 
rather than to insert it into a variable. Other than that, I removed all 
the variables, as they were getting used only once. Instead, I put the 
values that were going into the variables into the parameters. I also 
moved the selects into the parameters and reduced the choose to an if, 
since the otherwise was empty anyway.

FWIW

Here a bit of code which scatter each letter of a string into a vertical
set
of blocks (ie: vertical string):

             <xsl:template name="scatter-string">
               <xsl:param    name="text"/>
               <xsl:param    name="rotated"/>
               <xsl:variable name="len"><xsl:value-of
select="string-length($text)"/></xsl:variable>

               <!-- Concat the blocks containing each letters -->
               <xsl:value-of disable-output-escaping="yes"
select="$rotated"/>


               <xsl:choose>
                           <xsl:when test="$len > 0">
                                                 <xsl:variable
name="vrotated">
                                                             <xsl:text
>&lt;fo:block&gt;</xsl:text>
                                                             <xsl:value-of
select="substring($text,1,1)"/>
                                                             <xsl:text
>&lt;/fo:block&gt;</xsl:text>
                                                 </xsl:variable>
                                                 <xsl:call-template
name="scatter-string">

<xsl:with-param name="text">

<xsl:value-of
select="substring($text, 2)"/>

</xsl:with-param>

<xsl:with-param name="rotated">

<xsl:value-of
select="$vrotated"/>

</xsl:with-param>
                                                 </xsl:call-template>
                           </xsl:when>
                           <xsl:otherwise>
                           </xsl:otherwise>
               </xsl:choose>
             </xsl:template>


I hope this could help ;)

The following code prints top to bottom, but the letters are stacked. It's
a starting point.

<svg:text x="1" y="1" writing-mode="tb" glyph-orientation-vertical="0">
YOUR
TEXT HERE </svg:text>

The only workaround I know of would be to use SVG to draw the rotated
text...


HTH!

Greetz,
