Hup? Doesn't
http://xml.apache.org/fop/faq.html#svg-headless
help?

Maybe a problem with the scaling code. Or something else.

For SVG, the heigth/width in the SVG itself should match, otherwise
strange results may occur.
You shouldn't use pixels as units of measure, which may be rounded
in unexpected ways, use cm/in/pt instead.

No effect at all, these properties are never used in FOP for any
purpose.

The scaling code uses available height in the region *body*,
unfortunately. This doesn't quite explain why the top image
is rendered larger though, unless this is an artifact of the
screen renderer (Acrobat).

As look would have it... One of my installations runs AIX 4.3 w IBM
Java 1.3.1... Hence my attempt at avoiding SVG in my app... Ahh well...
At least the images work fairly well...

I'm successfully running an older Cocoon with updated FOP and Batik
Jars on an AIX 5.3 headless, using th headless option for Java 1.4.
A solution using PJA on AIX 4.3 ? IBM Java 1.3.1 was decommissioned
two months ago. Granted, setting up PJA for running in WebSphere 3.5
is a major PITA ...

erm... no. Thanks! I'll check it out!

One of the systems we use is AIX, and we were unable to get the
workarounds to function. I think the tip with "Xvfb" in it was the
closest we got, but we have problems we weren't able to resolve. We
weren't using SVG at all (so that wasn't an issue), and ended up using
outputting to Postscript instead of -print, and then cat'ing the
resulting file to a Postscript printer.

Ahhh... This is what I was beginning to allude to in one of my
updates... The Acrobat artifact possibility is interesting. I was
looking at the PDF at ~150% (page-width)...
Thanks for the comments!
