Subject RE: Problems with SVG display as background to region-body (FOP-Trunk)
Date Wed, 07 Jul 2010 17:25:06 GMT
I never got FOP to work with any images in external files, at least with
a reference which works on different machines.  I haven't had a chance
to revisit that yet but I will figure it out.  I had figured out a
format for the href which worked for svg and not for other image formats
but it was running on the server and when I tried it on the client it
also just displayed blank with a message in java console showing file
not found.  I was testing full http: and file: paths.  I didn't try
relative path because I wasn't sure what that should be relative to (my
program with the embedded code calling the fop classes, my fop.jar, and
my xsl file and image files are all in different paths).

If you're just using svg and putting it instream you could do what I did
for now and open the svg file in a text editor and copy and paste it
into the xsl.

Thanks Tom for the code. Tried it and still blank space where the svg
should be. (Tested with absolute and relative paths).

I'm not sure if this would help, but I've been able to use the trunk and
an external svg file like this:

          <fo:instream-foreign-object content-width='1.5in'
content-height='auto' text-align='center'>
            <xi:include href="images/value-xhairs-only.svg"/><!--
relative svg file name -->
          </fo:instream-foreign-object>

is built the same as those for PNG and JPG image files.
