hi,

i now tried it with gif, jpg, png and wmf ... all return the same !

cu,
-seb

this snippet:
-------------

...
<xsl:when test="function-available('simg:getWidth')">
  <xsl:message>
    <xsl:value-of select="$filename" />
    <xsl:value-of select="simg:new($filename)" />
    <xsl:value-of
select="simg:getWidth(simg:new($filename),$nominal.image.width)"/>
...

and this output:
----------------

./figures/imajpg.jpg
com.nwalsh.saxon.ImageIntrinsics@ce2187
540 (6 * pixels.per.inch = $nominal.image.width)

./figures/imagif.gif
com.nwalsh.saxon.ImageIntrinsics@141b571
540

./figures/imapng.png
com.nwalsh.saxon.ImageIntrinsics@1c5f743
540

./figures/imawmf.wmf
com.nwalsh.saxon.ImageIntrinsics@1bb60c3
540

with a .xml like this: (maybe imagedata with format-attr is needed? -we dont
use it)
----------------------
...
<figure id="FIG_Overviewofsystem">

	<mediaobject>
		<imageobject>
			<imagedata fileref="./figures/imajpg.jpg" />
		</imageobject>
	</mediaobject>
</figure>
