Hi Max,
I saw that application but did not realize that it could be used the way
you suggested (in a batch mode).
I now have two solutions to explore, yours and John's binary module.
Should keep me off the streets for a few days.
Thanks everyone. Very, very helpful.
Regards,
Mark

We had a similar task on one of our projects. However there was not so
many files, we also invoked an external utility to read the metadata.
We used Image Magick (imagemagick.org).
You can iterate over image files and call identify.exe with "-format"
option that contains XML tags:
<image>\n<file>%i</file>\n<width>%w</width>\n<height>%h</height>\n</image>
and redirect the standard output to file. Then as soon as you wrap the
contents of that file into the pair of opening/closing tags it becomes
a well-formed XML an you can read it from XSLT. And since performance
is a factor for you, it will be faster to use <xsl:key> for that purpose.
There's a handy installer of Image Magick for OS X at
http://cactuslab.com/imagemagick, if you're on Mac.

I have an XSL stylesheet driven by an XML data source that produces
about 5000 different pages, many with multiple images. I have been
adding by hand a placement-index to the XML data source that arranges
the images neatly, as with this page:
http://www.cpslib.org/amp/europa-themes.htm.
I am now faced with adding a huge number of images to a page or pages
like this:
http://www.cpslib.org/flaws/flaws.htm
I would like to add the placement-index to the XML data source
programmatically. Is there a way to obtain the height or width of a
jpeg image from the file itself (image.jpg, for instance) using XSLT?
Or, can someone suggest another way to do this programmatically?
Feel free to wander around the website if you find it interesting.
Thanks,
Mark
