Table column-width property
Hi,
I have a table with different column width.
I get column width in a variable. How do i assign to the column-width
property?
I gave it as,
where colwidth is a variable name holding the column width value.
But this value is not accepting and it gives the error :
Error in column-width property value "{$colwidth}"
Can anybody tell me how can i assign the variable to column-width property
Thanks and Regards,
Sujata

Seems to me you are trying to use variables in xsl-fo document instead of xsl
stylesheet. Am I right?

But this should be done in XSLT stage, there is no notion of variables in XSL-FO. Fromatting is two-step process, first source document is transformed to result tree using XSLT and then result tree is formatted by FOP. Get some XSL tutorial, that's really basics. -- Oleg Tkachenko Multiconn Technologies, Israel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Could not load external SVG
I upgraded FOP to 0.20.5 and now the error is different:: [ERROR]: Error while creating area : No ImageReader for this type of image (file:/D:/JD9/jdev/system9.0.3.1035/oc4j-config/ordpas/ord29396pas) Mentioned file is jpg without extension.

Re: Could not load external SVG
Please ignore this thread, I found reason why this happens - two files have zero length. >I upgraded FOP to 0.20.5 and now the error is different:: > >[ERROR]: Error while creating area : No ImageReader for this type of image >(file:/D:/JD9/jdev/system9.0.3.1035/oc4j-config/ordpas/ord29396pas)> > >Mentioned file is jpg without extension.

Fop and Multithreading.
Hi everybody! Sorry to bother you again with my problem (running fop with EJBs), I'd like to say that I still experience font corruption even if I use a singleton class (or maybe i didn't design it correctly). So we felt back to a sequential approach to print our documents. We just lost the speed we had when we tried to parallelize the documents' generation (3s vs 20s). So you can understand that when we have 3000 documents too print, this is rather annoying. If anybody had news about this subject, it'd be really welcome.

Antwort: Re: Fop and multithreading.
After some debugging and quite some time to get information on the
implications of multithreaded access to AWT/Swing classes, I came to the
following conclusion:
To keep thread-safety in Swing/AWT rendering operations can only be called
from one thread - normally this is the AWTEventDispatchThread. Swing/AWT
classes are NOT threadsafe by design.
The current situation:
a) in FOP singlethreaded: it is the main execution thread that does the
rendering. Because the AWTEventDispatchThread does not get any events in
FOP (no UI events) this is the only thread that really does something ()
-> no threading issues. The AWTEventDispatchThread also runs in this setup,
but does not do any work.
b) FOP multithreaded: multiple client threads call rendering operations
concurrently, -> leading to the issues we see. (again the
AWTEventDispatchThread runs, but does not do any work.)
Solution:
Threadsafety in AWT/Swing is normally achieved by delegating all rendering
calls from client threads to the AWTEventDispatchThread using
javax.Swing.SwingUtilities#invokeLater(Runnable runnable) or #invokeAndWait
(). This means one wraps calls to render into the BufferedImage into
something like:
SwingUtilities.invokeLater(new Runnable() {
public void run() {
graphics.setFont(font);
graphics.drawString(.);
}
});
I have considered to refactor AWTRenderer to work like this, but soon
realized that this means a complete redesign of the involved classes. For
several reasons I can't do this right now (FOP maintenance branch -> no big
changes, project work that is urgent)
Workarounds:
- wrap FOP into a singleton and synchronize the render method. -> does only
use one processor. Threads are potentially blocked for quite some time :
-((
or
- setup RMI / Corba Service / WebService that does the rendering, so we can
have several JVMs that contain their FOP instance and use some
load-balancing mechanism.
or
- use only one font / font size / color in the layout, it seems to work
then, by coincidence, though no guarantees.
I chose to go with the first for now, until I see that this causes
performance problems.
Additionally it might be good to document that AWTRenderer (and obviously
all subclasses) are not threadsafe.
Any comments?
Thanks,

Thanks for the testcase, Jeremias.
I got it running and can reliably reproduce the MT problems in AWTRenderer
with it, even on my single-processor NT 4.0 box.
I will have a closer look into the sources of AWTRenderer now...

Ok, I've put together a ZIP and put it under the URL below:
http://cvs.apache.org/~jeremias/FOPMTTestbed.zip
I hope you don't mind that it's heavily relying on Avalon (especially
Fortress). I've put all the necessary JARs in the lib directory. I
didn't include fop.jar and batik.jar which you can take from your local
FOP. I've also done a little Ant build.xml to make it easy to have some
fast results. You just have to adjust the FOP location in build.xml to
your local environment so it compiles.
To configure the whole thing look at FOPTestbed.xconf. There you can
specify the number of concurrent threads, which files to transform etc.
And finally, to test multithreading with the AWT Renderer just change
FOProcessorImpl.java accordingly. It currently generates PDF.
If you have questions, fire away. Happy debugging!

The best way to control page break.
Hi mates, I'm now using FOP for 2 months, we really appreciate this way to automatically generate our catalogs here. I have to work those days on a new XSL:FO layout that must manage fine page break system. Is there a better way for handling that than using the XSL string-length() and sum() with an xsl:if tag ? Maybe with the space-after properties ? Thanks for your help on this question. -- Simon OUALID -- ARTE FRANCE Analyste Programmeur [EMAIL PROTECTED] Tél : 01.55.00.70.70 Fax : 01.55.00.73.89 --

SVG is vector graphics, and is rendered as such into most renderers. If you use pixel units for width and height, they will be converted to real length units as if the resolution was 72dpi. Use real length units to avoid this. It is usually a good idea to use the same width and heigth on the fo:external-graphics, for example if the SVG is then use J.Pietschmann - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Look up DocBook, there is DocBook XSL at sourceforge. There is also a variety of other projects working with XSLT at sourceforge.
