Does anybody have a routine to reorder BIDI text?
You can use java.text.Bidi from jdk1.4 and sun.awt.font.Bidi in jdk1.2/1.3,
they provide basic BIDI facilities. The problem is that java.text.Bidi is
since jdk1.4 and sun.awt.font.Bidi does not exist in jdk1.4. So I suggest you
not to use BIDI implementation directly, but indirectly through
java.awt.font.TextLayout and so on.
I can't use Sun's Bidi class directly because some users will be
running jdk 1.3. I'll try with java.awt.font.TextLayout.
I'm writing code to visually reorder BIDI text before generating XSL-FO
files, but I don't want to reinvent the wheel.
btw, that's not the solution actually. This way you do provide visually
reordered text to FOP, but FOP as being BIDI-unaware will still layout text
ltr-tb, so you'll end with rtl-bt layout:
logical: RAC A SI SIHT
visual: THIS IS A CAR
One line is ok, but once line break occurs:
IS A CAR
THIS
The solution is to make FOP BIDI-aware itself. I have experimented with it
and
actually I have BIDI-aware version of FOP 0.20.5rc or earlier, but the
implementation is neither fast nor clean from design point of view, so I
decided not to commit it to cvs, but instead to implement it in FOP1.0dev in
a
better way. You are welcome to help us with this. Lack of free time,
unfortunately, you know, too many day works last time :
Can you send me the code? I can try to clean it. My deadline is March
7th, so I have 2 days to play with it.
Thanks and regards,
Rodolfo
