0.93: problem with fo:table, width="100%" in a page header

Hello all,

I have run into a "Cannot find LM to handle given FO for LengthBase" problem
that is related to a fo:table with width="100%" in a page header
(fo:region-before).

It seems that layout manager cannot find a relation between page header and
page itself to calculate the page header width.

I have a more or less distilled .fo sample file. Is it a good idea to post
it as an attachment here?

Regards,
Sergey

Check BugZilla if its already reported. If yes attach your sample to the
existing bug if not create a new bug and attach to that.

How to modify the log level in FOP 0.93 ?

Hi,

I installed a FOP as a servlet to generate PDF documents. Since this 
service is being running, a lot of messages, which I do not need, are 
being written in the log file.

Here is an extract of the log written in the catalina.out :

INFO: Source resolution set to: 300.0dpi (px2mm=0.08466666)
15 febr. 2007 14:16:25 org.apache.fop.apps.FopFactory initUserConfig
INFO: Default page-height set to: 11in
15 febr. 2007 14:16:25 org.apache.fop.apps.FopFactory initUserConfig
INFO: Default page-width set to: 8.26in
15 febr. 2007 14:16:25 org.apache.fop.apps.FopFactory getBaseURLfromConfig
INFO: base set to: file:/home/server/webapps/opencms/export/xsl/
15 febr. 2007 16:29:24 org.apache.fop.apps.FopFactory initUserConfig

I read that the file log4j.properties allows to modifiy the log level. I 
know that I should place the "log4j.properties" under the 
"WEB-INF/classes" directory.
But I do not know hot to write it. Can anybody expain me how to set the 
parameters in this properties file ?

Any help would be appreciated.

Best regards,

Xavier

You could use a table to mimic this layout. But you would have to 
manually break the text yourself at the end of the first cell of text (2 
column first row in the table). So this solution may not be acceptable

Is it large? If so, better not post it here, but you can mail it to  
me off-list if you want.

FWIW: I've already tried a simple table in a static content, and do  
not receive the error.

Recently, a similar problem was reported, but there the user also  
specified width="100%" on the cells, and that was causing the error.  
Be sure to check that. If that is the case, then removing the width  
property from the cells should solve the problem.

HTH!

Just FYI: I did a little follow-up on this on fop-dev <at> , and it seems  
to be a problem with scalability of the text-layout-algorithm. In  
your case, putting each of the scene-blocks in your example in its  
own fo:block already avoids the error.

Note that I did alter the FO to use linefeed-treatment="preserve".

The result looks as good as can be expected.

Ok, clear. 
Suppose i have a font that does allow me subset embedding in a pdf file,
but not full embedding. So far i have found out the following:
(I use FOP with CID-keyed embedding.)

Rows higher than expected

Dear FOP users,

I have a small problem with FOP (both 0.20 and 0.93).
When generating a PDF, I got an error of type "The contents of row 1 are 
taller than they should be", and in the generated PDF, the rows are higher 
than I expect.

I understand the error by itself, but not why it is generated.

For example, I have:
"the row grows to 21600 millipoints, but the row shouldn't get any taller than 
MinOptMax[min=opt=max=12000] millipoints"

But the font size I use is 12pt, and even if I add the 1pt padding on top and 
bottom, the result shouldn't be higher than 14pt.

Does anyone know why my rows are that higher? How the necessary high (21600pt 
in my example) is calculated? What elements are taken in account (font size, 
padding, borders size...?)?

Thank you for your help,
Slawick Charlier

Wrong. First of all theres half leading. Which means a line of text 
typically takes up 1.2x the font height.

1.2x 12pt = 14.4pt.

You don't show your FO, but if you have added 1pt padding top and bottom 
then the line height is up to:

16.4pt.

If your table cells have borders this may also increase the row height. 
There are many other things that can increase the row height, but rather 
than try and guess, post up the XSL-FO for the row in question and we'll
