Hi all, I had the same prob in my project. I made a little java class (based on some code i found on the internet) that calculate the actual width of my image. I call that class inside my xsl (thru xalan java extension). Then, according to some rules, i configure width="Xcm" inside external graphic tag.
Here is some example of my code : in the header zone : <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:fo="http://www.w3.org/1999/XSL/Format"; xmlns:java="http://xml.apache.org/xslt/java"; exclude-result-prefixes="java"> .... then in my xsl rule : <xsl:template match="ressource[@type='image']|ressource[@type='schema']"> <fo:block space-before="0.5cm" text-align="center" keep-together="always"> <xsl:variable name="image">temp\images\<xsl:value-of select="@URIsrc"/></xsl:variable> <!-- compute the width of my image... --> <xsl:variable name="pWidth" select="java:com.scenari.papier.Largeur.hValeur($image)"/> <fo:table> <fo:table-column column-width="{$gLargeurPapier}cm"/> <fo:table-body> <fo:table-row> <fo:table-cell> <fo:block> <fo:external-graphic src="{$image}" keep-with-next="always" width="{$pWidth}cm"/> </fo:block> </fo:table-cell> </fo:table-row> <fo:table-row keep-with-previous="always"> <fo:table-cell> <fo:block font-family="Helvetica" font-size="12pt" text-align="center" space-after="0.1cm" keep-with-previous="always" space-before="0.3cm"> <xsl:if test="@titre"> Fig. <xsl:number count="ressource[@type='image']" level="any" format="1"/> : <xsl:value-of select="@titre"/> </xsl:if> </fo:block> </fo:table-cell> </fo:table-row> </fo:table-body> </fo:table> </fo:block> </xsl:template> Hope this helps...
