Fw: [xep-support] viewBox with rotated SVG

Never mind, it's fairly easy when you rotate AND translate...

Hi,


I'm trying to rotate an image (eg. 5°) using SVG. Here's my (simplified) code (width & height in mm):

 <xsl:template match="PICTURE">
  <fo:block-container absolute-position="absolute">
   <xsl:attribute name="top"><xsl:value-of select="@TOP" /></xsl:attribute>
   <xsl:attribute name="left"><xsl:value-of select="@LEFT" /></xsl:attribute>
   <xsl:attribute name="width"><xsl:value-of select="@WIDTH" /></xsl:attribute>
   <xsl:attribute name="height"><xsl:value-of select="@HEIGHT" /></xsl:attribute>
   <fo:block>
<fo:instream-foreign-object>
 <xsl:attribute name="content-width"><xsl:value-of select="@WIDTH" /></xsl:attribute>
 <xsl:attribute name="content-height"><xsl:value-of select="@HEIGHT" /></xsl:attribute>
 <svg:svg preserveAspectRatio="none meet">
  <xsl:attribute name="width"><xsl:value-of select="@WIDTH" /></xsl:attribute>
  <xsl:attribute name="height"><xsl:value-of select="@HEIGHT" /></xsl:attribute>
  <svg:image xlink:href="{@FILE}" transform="rotate(5)"/>
 </svg:svg>
</fo:instream-foreign-object>
   </fo:block>
  </fo:block-container>
 </xsl:template>

The resulting pdf contains indeed the rotated image, but it appears to be magnified. Also, the viewBox attr needs to be set. Is there an easy way to dynamically set the viewBox based on the rotation angle in the XSL?
