Re: different Fonts in Same Line.
I want to add 2-3 different fonts in same fo:block. means in a paragraph there is serif,Richa,Arial in same line. If i use fo:block it will be in different lines. I tried with fo:inline-sequence.but was in vain. can anyone help me? Look at the samples. docs/examples/fo/testdeko.fo will help you.

Re: Java Extensions in Xalan vs Fop
I understand this error to be along the lines of a Can't find class BchDate, as I had the same problem with Xalan whilst learning how to implement extensions. I think you're right, as far as the semantics of the ERROR message is concerned. One reason you can't find a class is because you didn't compile the source; are you sure you have the _classfile_ available that corresponds to your BchDate class? Hi, thanks for the reply, Firstly, yes the class file is present on the class path. The class is compiled -- I can call util.BchDate (I've just packaged it to follow your example) from anywhere on the commandline and the function main I added to test the classpath works as expected, passes a dummy date to getDate, and the formatted string is returned. From this I take it that the java code is correct, works fine, and is present (compiled) on the classpath.. All is well in that regard. As previsouly mentioned, all my files work fine in Xalan. No changes need to be made _at all_ to get Xalan to run the Java and output an FO file. This is also true for the test files created with your example code discussed below: My final example is very close to yours. Here is the stylesheet root: Thanks for that, I've cut and past your example snippets into two new files, and the errors returned by FOP are the same. However, when the bchext namespace prefix is used I now get: Error: For extension function, could not find method java.lang.String.getDate([expressionContext]) To me this indicates that the xalan://util.BchDate prefix is being ignored entirely. I see no reason why FOP should believe that getDate is a method of class String and call it as such. It's not like getDate returns a string even! :-) So, with the failure of that may I ask you the following: Are you running this under NT? Where on your classpath did you put the util.BchDate package (ie: c:\data\bch\javacode\)? What version of FOP are you using? Any other suggestions?!

Markers; Other Stuff
The rudiments of fo:marker and fo:retrieve-marker support are appearing. Consider this a true commit early, commit often kind of endeavour; FOP doesn't break, the marker support should be transparent, and parts of it even work after a fashion (retrieve-boundary with a value of 'page', combined with some of the values of retrieve-position). But it isn't intentional at this point that any of it really _works_; consider it pre-alpha and untested. I am focusing on a nucleus of supporting markers inside fo:block (the lazy but useful approach) initially. I plan to gradually expand that out to other legal parents of fo:marker. You will have noticed other stuff appear; this not only supports markers but should support other stuff also: 1) AreaClass.java in 'layout': this is a utility class, basically. It supplies a verification method. I have never discovered a nice way of doing enums in Java, so I don't (we'll have to wait for 1.4 or 1.5, I guess). 2) Areas now have isFirst, isLast, generatedBy and returnedBy traits. Using them properly, or at all, is more a matter of Scout's honour than anything else, because of the way FOP is. Block.java shows how I am using them there. Finishing off marker support should actually not require that much more effort; I'm hoping to have it done within the week. If you happen to be working in a particular FO that can have markers, please add the support code if you like. More the merrier. Making sure that the traits listed in (2) are properly set on all areas we generate/return is much more of a task, but we have to start somewhere. As I say, everything should build, and existing stuff shouldn't notice any of this. Please let me know if that is not the case.

Re: FOP memory profile
Hi Mark,
I am also looking for this memory problem solution. I like your
analysis. Please do continue to work on it and apply the patches and
keep me posted.
Cheers,
Chetan Vig

Howdy fopsters
Yesterday I spent about 10 hours with FOP, vi, and a memory profiler
(JProbe 3 profiler - evaluation version, amazing product, but rather
expensive :-{ ). I have some observations of the FOP code that I
thought would be useful to share.
Firstly I understand that FOP is being redesigned. I followed the
thread there a bit and one of the main concerns, as I recall, was that
FOP is hard for newbies (like me) to understand. I would say that this
is not true. I actually found FOP reasonably easy to get around.
Considering that yesterday is the first time I've managed to really
get into the guts of it, and that I probably am familiar with only
half a percent of the code base, I would say that generally FOP is
pretty well written and reasonably straightforward. Perhaps there are
areas of it that need refactoring and documenting (and formatting to 8
character tabs ;) but from what I saw of it ... I figured that any
redesign would be equally impenetrable, as all large code bases are.
Anyway, that's just my .02c from the 'newbie FOP programmer'
perspective.
My goals for the profiling were to enable FOP to process large
documents with a standard environment (64Mb heap on JDK1.3.1 for
Linux). I have a 4,500 page document (containing a very simple
structure) and standard FOP dies at 600 pages. (By the end of the day
it was up to over 3,000 pages). I discovered the -buf argument and
tried that but that only extended the run to 900 pages and took about
3x the amount of time. My eventual goal is for fast processing of an
unlimited number of pages, but I'll personally be happy at 10,000
slightly more complex pages.
Basically what I discovered with the profiler was that there are a
large amount of objects being hung onto for a long time. (obviously
;). In particular, the Block object holds a reference to a BlockArea
object in a member field (blockArea), but the blockArea member is
referenced only twice in other methods for simple field calls. Making
the BlockArea a local variable for the layout(Area) method
significantly reduces memory consumption. (I'll post patches, if
desired, once the thread is complete). In otherwise unmodified code,
this change increased the number of pages I could process from 600 to
over 1,000.
Another object that's hanging around a lot is the Page object. This
one was more tricky and it took me ages to work out how to deal with
it, but finally I discovered that it appears that the processing in
FOP can be pipelined. So I hacked FOP to pipeline the format-render
cycle, so as each page is formatted it is sent to the (PDF) renderer
immediately. This hack allowed me to increase the page count to over
3,000 pages, but the problem is that the hack made the IDReferences
always empty. More on that shortly.
It seems to me from inspection and my limited knowledge of what I'm
doing, that it should be possible to completely pipeline FOP at the
level of the fo:page-sequence, without major changes to FOP. My
experience so far with pipelining the format-render steps was very
positive (it worked first time!) and I am interested in looking at
formatting immediately after receiving the /fo:page-sequence. I also
noted in my travels through the code that PDFRenderer seems to hang
onto a lot of stuff that it could probably write out immediately, if
it had a stream to write to. So, all this raises a few questions:
* How to deal with the IDReferences? (let the renderer deal with it?
do two passes?). I don't fully understand the full purpose and
implementation of IDReferences at the moment but at a guess it's used
to resolve forward references in the FO file...? I'm sure that it's
possible to at least optimize this.
* Is there something in XML:FO that means I can't process on receipt
of /fo:page-sequence?
* Am I just being stupid?
The benefits to this approach as I see it are:
* Probably not too many changes to FOP internals
* Will use significantly less memory even for small jobs
* Will increase the number of applications for FOP
I'm interested in continuing this line of experimental work if
anyone's interested. As always kudos to the developers, I spent a very
pleasant saturday with your code.
Regards
Mark Lillywhite

PDF serialization
Hi ho fops and fopettes, I have had a look at the memory use of my modified-for-streaming FOP executable and determined that the primary memory constraint is now in the PDF renderer. Basically, because the PDF renderer keeps all objects in memory until the end, this obviously limits the size of the output document. I can't say if other renderers have this issue because I haven't looked. I have had a look at the PDF renderer and I think it should be possible to serialize it with only a minimal amount of data being kept in RAM. However this will require extensive changes to the PDF renderer, because there doesn't seem to be a single point at which I can cleanly introduce the changes. Presumably these changes will be backwards-compatible with the current FOP since I don't want to actually change the code path, just make it so that the results are written earlier. So I was wondering if there was someone I should be speaking with directly about the changes that I want to make, or if I should just barge on ahead and make them, damn the torpedoes pip pip old chap? I would prefer some guidance about this because I don't actually know anything about PDF, but the code is well commented. Obviously my primary interest is in the PDF renderer at this stage, but I'm interested to know if other renderer writers are interested in my work? As an aside: is there a style guide for FOP code? I must say I find the style and layout very confusing and I'm happy to clean things up as I go. At the moment I can't even work out what tab stop size people are using. (In my own work I use 8 character tabs with 2 character indenting). Cheers Mark
Use of non-private member fields, etc
Hey there foptologists I was just wondering if there has been any discussion about private vs non-private member fields for the FOP classes. I have noticed that there are a lot of non-private (generally package-private default visibility) member fields and most of them do not appear to be referenced anywhere else in FOP. Unfortunately when changing a package-private field one must recompile the entire package to make sure something isn't thereby broken. If a field is class-private then one can be sure that it is not used anywhere else and can change it with (relative) impunity. Now I know that I am just saying stuff that everyone knows, so I was wondering if there was some explicit reason for the use of package-private or protected member fields instead of private members? Or is this just a consequence of the long history of FOP? I'm quite happy to refactor any code that I work on, this includes privatization and formatting cleanups, but I don't want to annoy anyone else who may have terribly good reasons for The Way Things Are. I am no PC (programming correctness) zealot, I've just found through personal experience that private member fields save a lot of pain. Am happy to go with the 'quo, tho. :-) Finally - is there an IRC server where FOP developers hang out? Cheers Mark
RE: PDF serialization
FWIW the PCL renderer should not be keeping much in memory. BTW earlier you had mentioned that the buf option slowed things down. I would expect that pipelining things would improve performance, has this been the case? If so, how much? It seems to me that with the exception of a few details (like ID References, etc) FOP would be an ideal application for pipelining.

proposed changes to AwtRenderer
Change summary org.apache.fop.render.AWTRenderer.java NB: we started from the 5/21/01 version of AWTRenderer.java, which was the latest as of Friday's cvs snapshots. The changes we're submitting, deal with the following 1. Background (colored) areas were being rendered in 3D, which incorrectly applied a bevelled look to the fill. 2. Drawing of lines (e.g., borders) ignored the border thickness and simply drew a 1 pixel line. We've corrected addLine to do the right thing. 3. The actual placement of a couple of the borders were incorrectly computed -- previously hidden by addLine ignoring thickness. This is fixed also. 4. Several places were subject to integer round-off errors, an example is that if you separately colored all the table-cells in a table row the backgrounds would sometimes show white gutters where one would expect the cells to bleed together. The same could happen if you put bottom borders in every cell -- they'd show gaps We realize this AWTRenderer is probably vestigial, in that it doesn't subclass the abstract PrintRenderer, and perhaps is destined for the scrap heap. In the meantime, however, these changes should make its end-of-life happier. At any rate, these changes improve ~our~ product's life. ;-) 'cheers Andy Langowitz [EMAIL PROTECTED] Ralph LaChance [EMAIL PROTECTED] apologies if we stepped on your tabs -- our environment is set to indent 2 cols AwtRenderer.zip - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

It looks like the CVS repository has moved to cvs.apache.org. This
is true for xml-fop and xml-cocoon2 at least. I just use the anoncvs,
so I don't know about actually committer userids, but I'd assume that
all that has been moved over as well.
If you're a UNIX user and you just wanna change the CVS admin files
in your checked-out copy of xml-fop, use the following to replace
all refs to xml.apache.org to cvs.apache.org in the CVS/Root files.
[ This is sh/ksh/bash compatible ... something similar would need to
be used for csh/tcsh ]
cd xml-fop
for i in `find . -name Root -print | grep CVS/Root` ; do
j=${i}.new
cat $i | sed -e 's/xml.apache/cvs.apache/' $j
mv $i ${i}.orig
mv $j $i
done
And change the entry in the ~/.cvspass file from xml.apache.org to
cvs.apache.org.

developed html to fo converter - mirroring FOP home page as PDF
Hello Fopper! I developed a html to fo converter and version 0.3 is just released. It converts the most used html tags and valid html should be correct processed. Non malformed html is also processed but don't expect to much. Like the xslt transformation, which was sometimes discussed here, it supports xhtml as input too. The project home page is available at: http://html2fo.sourceforge.net I want to mirror the FOP home page ( http://xml.apache.org/fop ) as crosslinked pdf files which are automaticly converted and generated. ( I am using the html sources from CVS ) This is to show what html2fo and FOP are able to do together. So I want to know whether it is allowed to mirror the site as pdf. I've put the pdf files in a non referenced directory for testing at http://html2fo.sourceforge.net/fop Cheers Enrico -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net GMX Tipp: Machen Sie Ihr Hobby zu Geld bei unserem Partner 11! http://profiseller.de/info/index.php3?ac=OM.PS.PS003K00596T0409a - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: Use of non-private member fields, etc
Hi, Mark I'd say that probably 75% of the instance/class variable visibility was well-chosen at inception, or at least had some thought behind it. But history, as you suggest, has very likely left some visibility too broad, and I'm sure some variables have been completely orphaned; others are probably still being set but aren't in use. It doesn't hurt to question the existence of any variable you run across, let alone the qualifiers. I think the usual rules apply to us in FOP just as they do to anyone else. If someone is using 'protected', for example, I would expect them to demonstrate (or suggest the reasonable possibility) of subclasses coming into play. I have deliberately used public instance variables - not many, but a few. I use them when I know for a fact that I am never going to represent the data any other way. I have seen classes (and FOP has a few of its own) that are unwieldy and hard to maintain because there are umpteen getters and setters that are never going to be anything other than pseudonyms for simple, direct access to a public member variable. My gut feeling (well, it's actually based on some experience) is that default visibility is an oversight, more often than not. We should also comment qualifier choices if they don't make obvious sense within the context of their own class. Regards, Arved Sandstrom At 09:38 PM 7/16/01 +1000, Mark wrote: Hey there foptologists I was just wondering if there has been any discussion about private vs non-private member fields for the FOP classes. I have noticed that there are a lot of non-private (generally package-private default visibility) member fields and most of them do not appear to be referenced anywhere else in FOP. Unfortunately when changing a package-private field one must recompile the entire package to make sure something isn't thereby broken. If a field is class-private then one can be sure that it is not used anywhere else and can change it with (relative) impunity. Now I know that I am just saying stuff that everyone knows, so I was wondering if there was some explicit reason for the use of package-private or protected member fields instead of private members? Or is this just a consequence of the long history of FOP? I'm quite happy to refactor any code that I work on, this includes privatization and formatting cleanups, but I don't want to annoy anyone else who may have terribly good reasons for The Way Things Are. I am no PC (programming correctness) zealot, I've just found through personal experience that private member fields save a lot of pain. Am happy to go with the 'quo, tho. :-) Finally - is there an IRC server where FOP developers hang out?

Re: Spanning a table over many pages
OK, I'm attaching a zip file containing three .fo files. They are all generated from the same data (I manually modified the title of the report). The file called threecol.fo is a three column report that generates 2 pages (correct). The file called fourcol.fo is a four column report that generates 2 pages but truncates some data. The file called fivecol.fo is a five column report that only generates 1 page, the whole 2nd page is truncated. I looked at them, but am not quite sure why the renderer treats them differently. Thanks again.

Which version of FOP are you using? There is a bug fix in CVS for a problem which sometimes caused tables to overestimate the space left on the page. If it's possible for you, you may want to try using the latest CVS version of FOP. Or post the FO file which is being created by your XML and XSL so that I can check it out.

When the 1st page of the flow fills with table rows, a new page isn't being created -- when I run FOP only 1 page is created with all of the additional rows just running off the bottom. (This should produce a 3 page report -- 1 table spanning 3 pages) Do I need to specify pagination values for the table? What am I doing wrong? Thanks in advance.

RE: vertically centering contents of table-cell
Eric, I had this requirement (well more correctly, I needed display-align='after') and the first thing I tried was to comment out the first line of real code in setRowHeight(int), ie. cellArea.increaseHeight(h + borderHeight/2 - cellArea.getHeight()); Now this makes display-align work (sorta) but mucks up the border and background for any table cells where display-align is not the default (before?) For the moment this is acceptable to me but probably not to the project as a whole. TTFN Struan Judd * And so it begins ...

From the code (specifically, org.apache.fop.fo.flow.TableCell.setup() and setRowHeight(int) ) it looks like display-align should be supported, but it seems that setRowHeight() is not being called. At least, I set a breakpoint in that method and it never halted execution. Being a FOP newbie, I'm not sure how to fix this problem.
