Thomas,
Thank you for response.
I am not sure the version of Batik. The modified date for the
directories under xml-batik is 7/24/2003. But fop version is
0.20.5.

Agreed, however I suspect that part is a FOP issue, you
may want to try the trunk this will (if nothing else) put
you in a position to make use of any fixes they can provide.
As a side note I noticed you reference FOP.sh are you
running this on Windows (cygwin) or UNIX. I have noticed
that FOP hangs quite a bit for me when I use FOP.sh with
cygwin and never when I use fop.bat. Cygwin does not seem
to play well with java.
Actually the generated pdf file is
fine. ( We have a gui and a batch reporting application to
generate pdf file. User may mistakely reference to some wrong
file. But once fop.sh hangs, user can not continue to use GUI or
run batch job).
Not that it's particularly relevant here, but this seems like a
problem to me beyond any issues with FOP.
As for the text position, SVG 1.1 spec does not mention the X,Y
coordinates are the base line position. If you choose x/y as
base line position, it is very difficult to position the text
field, because the font size change may cause the starting
position change and thus may cause overlap.
I think you need to read your copy of the SVG specification
a lot closer if you want to generate content. In particular it
has a rather large section on how text is laid out in SVG in
particular the handing of baselines.
As to why text is laid out on the baseline and not by the
upper left corner, the answer is: because this is the only
sane way to layout text _especially_ when you can have the
font size change. What I can't understand is why you think
that specifying text by the top corner avoids overlap when
the font size changes?
To do text layout properly you need to know a lot about
the font you are working on, having to know the ascent of
the font is likely the least of your concerns.
Thanks.

Hi Jay,
I added Batik-users to the CC list as it seemed many of
your
questions are really SVG/Batik questions.

I have tried to embed a svg into a fo file to generate pdf

The svg contains a reference to an image that can not be

I got fop hanging problem. I hope Batik team to coordinate
with
FOP team to solve this issue for me.
Attached please find the test svg file, fo file and
generated
pdf file.
Here are the descriptions of the issues:
(1) SVG side:
(a) If I open the testimage.svg in Squiggle GUI, the GUI
shows
the SVG error null with the stack:
java.lang.NullPointerException
What version? With current CVS and squiggle I get:
file:[...]/textimage.svg:7
An I/O error occurred while processing the URI
'file:[...]/unfound.jpg' specified on the element <image>
(b) A text element with x=0, y=0 is not displayed from
(0,0)
position. It can not be found on the image. Is this right
behaviors?
Actually if you look _very_ closely you can see a little
bit
of the 'p' at the top of the image. 0,0 establishes the
baseline
for the text, for most languages the text sits 'on top' of
this line.
So in this case most of your text is off the top of the page.
If you move that line down a little to say: 0,10. You can see
all
of it. So yes this is the right behavior.
You can also tell batik what section of the infinite
canvas to
render by setting the 'viewBox' attribute on the SVG element.
(2) FOP side
FOP successfully generated the pdf file(as generated), but
it
hangs in cleanup. The output of Fop.bat is:
C:\apps>fop-0.20.5\fop.bat textimage.fo textimage.pdf
[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2
