I am using j2sdk1.4.1_04, batik-1.5. that file displaying in the batik

attached file.
I've done some checking and I am 99% certain this is a bug in the
1.4.1 JDK, and the work around in Batik would be extremely nasty.
However I can suggest some content workarounds.
Basically the 1.4 Bidi code doesn't like it when you set the BIDI_EMBEDING
property for the first character in a 'paragraph' contrary to what it
considers the default BIDI direction for that character.
To work around this you can ensure that the first character in the
text element has no BIDI attributes (probably by making it a space in
a tspan with xml:space="preserve"), you can then use x/y etc to arrange
for the rest of the text to appear where you want and how you want:
<text><tspan xml:space="preserve"> </tspan><textPath xlink:href="#t_32"
><tspan unicode-bidi="bidi-override" direction="rtl"
>mxet</tspan></textPath></text>
I am still looking at a possible workaround but it would fairly
significantly negatively impact the performance of the normal case so I
am extremely reluctant to do so.
Thanks for sticking with me on this, Thomas. That's a nuisance for me - I
can't go back to 1.3.1 for lots of reasons, but I could go for a later
version of 1.4. Does anyone else have any experience of this - does it
work
with other flavours of 1.4 ?
Cheers
Chris

Thanks for giving me the example. I added a white rectangle to

batik-rasteriser.jar <file>" and create the png. I am on batik
1.5 with JDK
1.4.1_02 - my image is attached.
Hmm, I was using 1.3.1 and it works with that. It does not work with
JDK 1.4.1 - We have seen some similar problems in the past because they
'upgraded' the bidi engine in 1.4 in the past when we have had problems
we were doing 'bad things' - however in this case I think we are doing
the 'right thing'. If you are interested in looking into this we
set all the BIDI attributes on the text in
xml-batik/sources/org/apache/batik/bridge/SVGTextElementBridge.java:1439
I don't know if I'll have time to look at this in more depth
right now.

Hello
I am trying to get rtl-oriented text to work. I have batik
1.5 - in the

You need to add set the "unicode-bidi" property to
"bidi-override".
<path id="t_32" d="M498376,252804L498399,252818L498627,253000"
