content-width and content-height ignored?

           Summary: content-width and content-height ignored?
           Product: Fop
           Version: all
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: svg
        AssignedTo: fop-dev@xml.apache.org

I am trying to scale an SVG image, by using external-graphic with
the content-width and content-height attributes set.

Unfortunately whether I use "scale-to-fit" (to fit the width/height attributes),
or an explicit length, the graphic itself is not scaled.

I was not 100% sure that content-width and content-height should scale
the image, so I looked at the "XHTML to XSL formatting objects" example
XSLT file at http://www.antennahouse.com/axf11sampleEN.htm.

>From there it looks like I'm generating the right XSL, and FOP is
not scaling the images as it should.

I have seen the example of a scaled image in the FOP documentation.
It uses an instream-foreign-object SVG, which references the external
SVG using "svg:image" and explicitly set width and height.

This does rescale the image, but unfortunately there is no way to have
the image size determined from the layout context.  For example, XSL
sizes such as "80%" to show an image with 80% of the width of the
current reference port do not work.

I am stuck working around this problem by using explicit sizes, and the
instream-foreign-object method for rescaling the image.

It would be nice if content-width and content-height were honoured.

cheers,
