<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>This is possible to accomplish without “two passes”
but does require special processing of the intermediate format file (<a
href="http://www.renderx.com/reference.html#IntermediateFormatSpecification_Specification">http://www.renderx.com/reference.html#IntermediateFormatSpecification_Specification</a>
). This is similar in nature to the Transpromo application we created for
a customer. Take a look at this white paper from the RenderX web site (<a
href="http://www.renderx.com/solutions/wp_transpromo.html">http://www.renderx.com/solutions/wp_transpromo.html</a>).<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The problem here is to inject a variable size image into a
document. Think of your monthly statement from a bank. The last page frequently
has available white space below the last line items and summary. The image to
inject is based some parameters from your account (like balance) and of course on
available white space. The solution lies in the fact that RenderX supports a
hidden extension element <rx:pinpoint>. This element has a “value”
attribute and when dropped in the FO source, it will be placed in the RenderX
Intermediate Format (xml) file. The Intermediate File can be obtained from
RenderX software for any application using the API or even command line. You
can then process this intermediate file to “find” pinpoints. In the
intermediate format, pinpoints carry the “value” attribute as a
marker for you as well as attributes about its position on the page (x, y
location) like this:<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN style='font-size:10.0pt;font-family:"Courier New";
color:black'><xep:pinpoint x="56693" y="262888"
value="promo,96;promo1.jpg"/><o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>So, in your application, one could measure the height of this
table cell using two <rx:pinpoints> and then using a little XSLT math
find out the height. Better, if you fill the table cell in question with a
specific color, then you could search the intermediate file and find and extract
the dimensions of the <xep:rectangle> that is that color and you will
know the exact size of the space. This would be like this but preceded by your
color:<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<pre><span lang=EN><xep:gray-color gray="1.0"/><o:p></o:p></span></pre><pre><span
lang=EN><xep:rectangle x-from="56693" y-from="56693" x-till="526693" y-till="262888"/><o:p></o:p></span></pre>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Then, without even reprocessing anything, you could modify the
intermediate format to add the SVG with the proper height and then send the
intermediate file to the RenderX backend. You would only need to convert XEP
units to your units but this is easy as XEP units are 0.001pt.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>All of this could be done programmatically without human
intervention and the RenderX team uses such techniques all the time in custom
situations for inserting OMR marks, special barcoding, concatenation of huge
mail packages, custom layouts that span columns, etc.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>In addition, there is another white paper that uses this same technique
to measure areas for PDF form fields and dynamically creates a fillable form by
calling iText software with the intermediate file “measurements” to
stamp the form fields. This paper is posted here: <a

<p class=MsoNormal><br>
You should set the viewport's area using @width and @height attributes on the
fo:external-graphic element.<br>
<br>
If @width and @height are omitted then they are treated as 'auto' and it means
that viewport's area equals to the intrinsic size of the graphic.<br>
<br>
And what you do is scaling the intrinsic size of the image to the ... yeah, to
the same value.<br>
<br>
So, in order to scale the graphics width to a table cell, you need the following:<br>
<fo:external-graphic width="100%"
content-width="scale-to-fit" src="..."><br>
<br>
But you cannot scale the image's height to an arbitrary block (a table cell in
your example) using a percentage value because the height of this block depends
of its content.<br>
So you should know the height of the surrounding box ahead and specify this
length as a value of @height on fo:external-graphic.<br>
