There are two axes to address:

1. With regard to "build clean" still having problems, since the JDK is 1.4, 
there is a known issue with that platform, documented at 
http://xml.apache.org/fop/relnotes.html. The specific item is currently bullet 
#6 under the heading "FOP 0.20.4", and a solution is suggested there. An 
alternative solution is to build under JDK 1.3. Please confirm whether 
addressing this issue (along with "build clean") makes the build complete 
successfully.

2. With regard to the dependencies in the build file, J.Pietschmann is correct 
that there some issues. I'll be glad to track the problem down if you will 
document the steps that make it fail.

Re: Encoding Filters(Formally Re: Hope this helps- RunLengthEncod eFilter)

Manuel

Looks like I missed this. At least, I can say that I could profit from
CCITT group 4 because we have a project at work where we have to include
several different monochrome images in a lot of documents. So this may
decrease file size when compared to the FlateEncodeFilter. If it's
dependent on JAI, so be it. That just means we have to make it optional,
somehow. Want to send a patch?

I agree with Arved. I think it's a small change with a reasonable chance
of improving things a bit.

It was just an idea. Not really needed. I don't know what's the best way
to implement it, but let me tell you this: Don't do it if if it's not
fun for you AND if you don't need it, because there are a lot of other
things that are more important if you like to contribute more to this
project.

RE: Encoding Filters(Formally Re: Hope this helps- RunLengthEncodeFilter)

I did (sort of) integrate the CCITT/TIFF compression based on JAI earlier

Jeremias

I would love to have some fun, but is this your idea of fun?? ;-)
I will take you up on the offer, report back and tell you whether it was
found to be fun or not.

Also, I had looked into the CCITT filter briefly and noticed at that time
the JAI API has this  and many other encoding filters in it. When trying to
see how much work it would have been to integrate the JAI into the FOP I
noticed the FopImageFactory has some commented out code that would lead me
to believe I was not the only one to consider the route of having the JAI
handle the images.  Now to my question.  Was this just a passing thought or
is this the direction being forged or does anybody know?  I am just curious.

Lastly, to clear my foggy head, my understanding is that the CCITT encoding
is fax encoding is intended for encoding in black and white only and is some
how related to the Tag Image File Format (TIFF).  Is that a correct
understanding?


Thanks,

Hi Stephen

I've committed the filter to both maintenance and main branches. Your
code seems to work well, but obviously doesn't bring much for color
images because they are currently encoded as a mixed data source
(RGBRGBRGBRG, for example). To profit more from RLE compression we would
have to encode 3 (or 4 for CMYK) separate channels which required some
more work (would result in RRRGGGBBB). But at least for greyscale images
(when only working with PS Level 2) the RLE filter should produce
considerably smaller files. Would you like to have some more fun
implementing a CCITT filter? :-) The PDF renderer could profit from this,
too, I guess. Thanks, anyway!

Hello master-hand:

I using JAVA only one year!

My boss order me analyse FOP,and rewrite in C++;I think it's impossible!

Now,I want to know.How long time I can find out the design about FOP complete? 
Otherwise I am 22 old,  experience less one year!

Seems reasonable to me, Oleg. The default constructor for ArrayList creates
an array of 10 Objects. An inexpensive check for null in addChild() is
unlikely to cost more, even over many children, especially averaged over an
entire document.

Case 2 might be overkill, unless one can make the case that single children
are frequent enough to make this extra logic worthwhile. Comments?

PDF Security using FOP.

[Avula, Raj]

Hi,
I have a basic question about the generated PDF document using FOP.
It is possible to apply security features to PDF output like making pdf
output read-only
and disabling the copy operation on the output etc..

Thanks for the help.

just a thought

[Oleg Tkachenko]

Hello!

It's probably not too late to consider some trivial optimization of fo 
tree in redesign code. In a typical fo document probably about 30% of 
elements have no children or have only one child (text node usually), so 
instead of eager
protected ArrayList children = new ArrayList();
in FObj.java we can consider lazy polymorphic member
protected Object children = null;
1) For no chidren case it remains to be null.
2) For 1 child case it is FONode object.
3) For children case it is ArrayList.
This means some additional logic must be implmented at addChild() and 
getChildren() methods.

Any thoughts?

The scissors appears to be what ZapfDingbats displays for
the default unmapped character. You have to use proper
Unicode codepoints for the characters you want to see, for
example, try
  
   ➯
  

You can find the Unicode code points for the characters
in the ZapfDingbats font in the FOP soure distribution
in src/codegen/charlist.xml, all the mappings with
adobe-name="aNNN" with some NNN number.

Font question

[Jessica Perry Hekman]

http://xml.apache.org/fop/fonts.html says:

 FOP (building PDF files) normally supports only the base 14 font package 
 defined in the Adobe PDF specification. That includes the following 
 fonts: Helvetica, Times, Courier, Symbol and ZapfDingbats.

I have in an FO document:

 
  Symbol 12345
  
  
  ZapfDingbats: ahijk '"\] 12345
  

In the PDF generated by FOP, I see:

  ## 12345

and then a bunch of images of scissors for the ZapfDingbats text.

Surely that can't be right; I expected to see more varied Dingbats :) Am I 
doing something wrong? Is this really the expected output for those fonts?

Duplex printing problem. Please help.

[IvanLatysh]

Hi.

I have problem with printing on duplex printer HP LaserJet IIISi.
Report have 2 pages.
If I am printing simplex - Ok.
But if I am trying to print duplex only one side is printing, but printer flipping the 
page and
indicate that it is duplex printing.
The second page is going to another page, like simplex printing.

I did check, there are only 2 pages, nothing between.
This is page declaration:





Using FOP 0.20.3. Printing from AWT preview window.

Sincerely yours, Ivan Latysh.

release 0.20.4 - custom fonts broken

[Erik_Vanherck]

Extract from the Changes file :

- BaseDir property is now used for loading custom fonts (Bug #7608)
  (thanks to Arnd Beissner and Brian O'Kelley)

Applying this fix broke some stuff as far as I can tell. Fop ships with a
config file that has this property commented out. As a result basedir
appears to be null and FOP tries loading fonts with something like
nullfonts/metrics/arial.xml which of course does not evaluate to a decent
filename. Ok after figuring that out I set the basedir to ./ which is in my
case correct for loading fonts. Doing this however breaks SVG cause it
tries to set the basedir as the url of the SVGElement causing the following
exception to be thrown

java.net.MalformedURLException: no protocol: ./
at java.net.URL.(URL.java:473)
at java.net.URL.(URL.java:376)
at java.net.URL.(URL.java:330)

at org.apache.fop.fo.pagination.PageSequence.format(Unknown Source)
at org.apache.fop.apps.StreamRenderer.render(Unknown Source)
at org.apache.fop.fo.FOTreeBuilder.endElement(Unknown Source)


A better solution to the font loading problem would be something like a
system property I think (eg. if you were to define
org.apache.fop.fontbasedir
and prepend it to the embedded font filename). At least this solution would
allow the font base dir to be specified at runtime which is important for
embedding.

If you don't test then your code is only a collection of bugs which

Tasks - layout

[Keiron Liddle]

Now that we have some pagination there are lots of areas that people can
work on. 
If you want to implement any of these and have any questions then just
ask. 

Once we can get a few of these done then we could do a developers
release. 


- Add static areas to page 
The static areas will need to be handled in a similar way to the flow
except the bpd is unlimited and it will need to reset and repeat for
each page. 


- Add id areas to page when area added 
When the layout managers add an area to the page it can also add the id
information. 


- Resolve id references on other pages, extensions 
When an id is added to a page this will allow id references to be
resolved. 


- Add markers to page when areas added 
When an area is added that is created by an FO that contains markers
then the markers can also be added. There are four types of positions
for markers. 


- Retrieve markers from page 
When doing the static areas the markers wil need to be available for
retrieving. The marker can then be layed out as normal. 


- calculate line height 
The line height needs to be calculated while finding breaks. This needs
to include all the alignment and height details of the inline areas. 


- Various inline objects
Page number, page number citation etc. need to be implemented.


- Implement page caching 
If a page need to be stored for the store pages or waiting to resolve
forward references then we need a cache mechanism to save the page
somewhere. 


- Implement table layout 
The table layout will use the same technique as the block layout. It
will locate suitable breaks between rows or inside rows until table
finished or end of bpd reached. 


- Implement list layout 
The list layout like the table layout will be looking for suitable
breaks from the child objects. The it will add the appropriate areas to
the area tree. 


- Get bookmark extension working 
Make sure the extension id references are resolved. Once the data is
fully resolved then implement a way for the pdf renderer to add the
bookmarks. See branch for code how to add bookmarks. 


These are just some of the things, I will add them to the todo list.
If there is a decent response then there are more that can be added.

This is a mailing list for people working on the source code
of FOP, a Java implementation of XSL:FO.

You may want to check www.xmlsoftware.com or www.w3.org. There
you will find lists of free and commercial implementations
of XSL:FO renderers.

Hope this helps,

No. FOs create layout managers. Layout managers refer to FOs. Layout
managers create areas. The only place that areas are held onto is the
area tree. The page sequence layout manager holds onto the area tree to
add pages. The area tree then handle how the pages are used. If a page
is rendered then it is cleared.
The layout managers can then release FOs that are done with and the
areas are not held onto.
I don't know where you get the idea that a lot of small objects are
used. Remember it is not finished yet.
Peak memory usage should be: largest image currently loaded temporarily
+ at least one fo block (but not much more) + one page area + render
stuff + common (static pagination) areas. A bit hard to define but I am
certain the result will be less memory.

Does that mean we should not attempt to solve this problem?
Or that we should attempt to solve the problem twice independantly.

As far as I know there is never a case where a finished page should be
redone. Once a page is complete that is it.
Those problems should be solved during the layout of a page only and not
considering furture pages.
