svg image is to large and hence truncated when converted to pdf

[jw2k1888 Wright2k1 <jw...@hotmail.com>]

Hi all,

I am currently using xsl/svg to transform an xml file into svg report 
graphs.  The result is an svg image(file) that has 1 or more graphs stacked 
above one another depending upon the data in the xml file. Like a vertical 
list of graphs.  I would like to export this xsl/svg output (svg graphs) to 
pdf format but when I attempted this the pdf file comes out with only 1 page 
which is the very top of the svg image?

Is there anyway of using xsl:fo so that if the svg image's height is like 
2000 pixels high the pdf conversion would recognise that the first 600pixels 
would be page 1 and the next 600pixels would be page 2 and so on?

simple analogy:

XML file:

<root>
</root>

XSL/SVG file:

<xsl:template name="2pageExample">
   <xsl:param name="counter" select="0"/>
   <xsl:param name="max" select="100"/>

   <svg:text x="50" style="fill:rgb(0,0,0)">
      <xsl:attribute name="y">
         <xsl:value-of select="$counter*20 + 50"/>
      </xsl:attribute>
      Blah
   </svg:text>

   <xsl:if test="$counter != $max">
     <xsl:call-template name="2pageExample">
       <xsl:with-param name="counter" select="$counter + 1"/>
       <xsl:with-param name="max" select="$max"/>
     </xsl:call-template>
   </xsl:if>
</xsl:template>

This would print out "Blah" text 101 times, creating a list of Blah text 
that spans over an equivalent of 2 pdf pages.

Now when I apply

   <fo:block>
      <fo:instream-foreign-object>
           <svg:svg width="550" height="660">
                <xsl:call-template name="2pageExample"/>
            </svg:svg>
      </fo:instream-foreign-object>
   </fo:block>

I get one pdf page with the an incomplete list of blah text...

I've tried <fo:external-graphics> which produces a two page pdf file but 
page 1 is blank and the list of Blah text starts on page 2 and then gets 
truncated.

I've tried placing it in <fo:tables> but it only works with normal text and 
not svg generated text file.

Any sort of assistance or sugguestions would be greatly appreciated, Thanks.

Regards,

Jason.

No. You'll have to split it into several SVG objects explicitely,
like

<xsl:template name="2pageExample">
   <xsl:param name="counter" select="0"/>
   <xsl:param name="max" select="100"/>
   <fo:instream-foreign-object>
     <svg:svg width="550" height="660">
       <svg:text x="50" style="fill:rgb(0,0,0)" y=0>
         <xsl:text>Blah</xsl:text>
       </svg:text>
...

BTW

Using pixel units is unwise. Use cm/mm/in/pt instead.
And

>   </svg:text>

This will surrout "Blah" with probably unwanted whitespaces.
Use
  <xsl:text>Blah</xsl:text>
instead.
