Re: Example extension

[Matt Savino]

I've been told than an extension is the way to go for these two needed
features:

1. Add a string ['(Continued)'] to a table header if the table spans
multiple pages. Note these tables are part of the content and can start
anywhere in the page. They could be seen more like paragraphs or blocks
with a title. Any other solution to this problem is acceptable. 

2. Separate page number display for a subsection. IE - master document
is page 4 of 7, but subsection is page 2 of 3.

Please let me know if I'm missing any existing functionality that solves
these problems. I am planning to look into writing an extension some
day. An example would certainly help.


In the meantime, someone mentioned using iText for final stage add-on
functionality like this. Does that make any sense here?

Thanks a lot,
Matt


BTW, if anyone is in there poking around with the redesign, and feels
like creating a table-add-something-different-to-header-after-break
property, or even table-omit-header-before-break, I'd certainly love you
for it.

RE: [REDESIGN] TextLayoutManager whitespace handling

[Arved Sandstrom]

No, I am not sure about that, not 100%. :-) But 7.15.12 does say that
"white-space-treatment" and "linefeed-treatment" happen during refinement,
but that "white-space-collapse" happens during area tree generation.
Considering the meaning and intent of the property it seems to make more
sense at the time of area generation, anyway. But the language bears me out,
I think.

Arved, are you sure about that? It's a bit confusing since the spec
(actually it's 7.15.12 not 7.5.12 as I mistakenly wrote last time) says
white-space-collapse happens during area building but only talks about
adjacent flow objects not at all about areas. Well actually it does. It
says that the collapsed space doesn't "generate an area".
I thought only the "suppress-at-line-break" (7.16.3) was actually based
on areas.

I agree about the definition of ajacent areas (4.2.5) and I don't
believe there is a clear definition of ajacent FO, so maybe it's best to
follow your interpretation.

In fact, my white-space-collapse code in the new Fop is currently
collapsing them during FO tree construction (== refinement) after doing
the white-space and linefeed handling. So if it's supposed to deal with
areas it's not right.

Problem with TTFReader

[Richard Waginger]

I tried to convert times.ttf font from my winXP fonts directory, but I failed. I used 
the command like in example on font support page, but program allways ended with 
exception: 

command: 
c:\Fop-0.20.2>java build\org.apache.fop.fonts.apps.TTFReader 
C:\windows\fonts\times.ttf C:\fontmetrics\times.xml 

Respond: 
Exception in thread "main" java.lang.NoClassDefFoundError: 
build\org/apache/fop/fonts/apps/TTFReader 

Later I tried many variants (e.g. without "build\" or c:\Fop-0.20.2>java -cp 
build\fop.jar;lib\xerces.jar;lib\xalan.jar;lib\batik.jar 
org.apache.fop.fonts.apps.TTFReader ... ) but with same result. Where is the problem ? 
In configuration of JDK or where ? (I use JDK 1.3) 

Please help me, thnx

Please see my post re PJA for a solution about this, or use Xvfb.

Setting the DISPLAY variable is going to cause you big problems if the X 
server you are connected to goes down.

Hi Boby,

The prob is that svg renderer *need* to connect to an
X11 server cause batik relies on AWT. When you run it
via the command line there is no prob (assuming you
actually are connected to some kind of X11 server). I
found a workaround by running servlet container in a
shell where i export correct DISPLAY variable first. I
know it's a little bit dirty but i don't know any
better solution...

converting SVG to PDF

[Lewis, Bobby]

I'm running the example that comes with fop, embedding.fo (in
examples/svg/). When I do it command line (to convert this XSLFO that
contains SVG into a PDF), it works fine. I open the PDF and see a picture of
a tiger.  

Now, I try to do it on the web. The JSP (that works correctly with examples
like border.fo that do NOT use SVG) takes an XSLFO file, and converts it to
PDF, then returns the byte stream with a header of application/pdf. When I
try it with the SVG FO file, I get:

Can't connect to X11 window server using ':0.0' as the value of the DISPLAY
variable.


It's like it's trying to render the SVG to a display on the server side. I'm
explicitly calling  driver.setRenderer(Driver.RENDER_PDF);
so that it renders PDF and not AWT or Print or something else. I get this
stack trace BEFORE the driver.run method returns (it's all happening
somewhere in the conversion process):

RE: Corrupt PDF files?

[Lewis, Bobby]

Good idea, but I tried to look into doing the same in
org.apache.fop.apps.Driver. The problem is there are too many classes in
there that I don't have (where do org.apache.log and org.apache.avalon come
from?)

Has anyone tried this with Driver? (Manually editing it to close the stream
at the end of the run method)?

I had the same problem, but it was because the OutputStream is not closed in
method run() of the class CommandLineStarter of the FOP library. I patched
my FOP and closed the OutputStream, and have no more problems...

If you use this class try to close the Stream...

Objet : Corrupt PDF files?


I have a problem that is hard to debug. I am generating PDF files with FOP,
and the process is working ok most of the time. Sometimes though, the file
becomes corrupt (I'm sending the PDF back to a web browser based on a
request a user makes from a JSP).

Here's what we just found: we're using an external barcode font (a Code39
font). If we take the font out and don't use it in the PDF, it works fine
everytime. Otherwise, it works sometimes. There's no discernible factor as
to why it does/does not work, so I'm thinking there's something buggy in
FOP. Has anyone had any kind of unpredictable behavior before with FOP when
using external fonts? I'm using a TTF, I generated the metric file ok and
everything, because the barcode does show up correctly SOMETIMES.

Any help is greatly appreciated.

RE: EBCDIC os390

[Jason . West]

Anyone have any documents on how the software works already to help 
me speed up where to look and what to patch? What it looks like to me,
is that there are some compressed streams inside the entire pdf stream.
So, a conversion at the final output won't work; appears to convert the
non-compressed parts ok though.

Thanks, Jason

Ben Fowler posted a similar mail two days ago.

You're in the same boat. I think it would be good if you one of you two
could really track down the problem, create a patch for it and post it
to the list for inclusion into FOP along with some documentation
(guidelines) what has to be done to ensure non-ascii-environment
compatibility in FOP for the future.

Re: Options

Jeremias

The files are *rather*, but not *entirely* static, especially scripts at 
the moment.  It seems to me that in principle such file should be able 
to be changed completely independently of the code base.

AW: output PDF via java.io.Writer

[Beer, Christian]

> Is it generally possible to output a pdf stream via a java.io.Writer
object?

Well a java.io.Writer is used for character output. A PDF is binary output,
especialy if you use filters (Flate, ...)

I think it could be possible, but no good idea! The problem is, that a
writer
handles character data (2 bytes) and it can convert the data (for example
"\n\r"
to "\r" or something) and then the offsets in the PDF don't fit any more.

The more I think about it, I'd say "let it be", also because a JSP is
constructed
to return character data, not binary. We tried to implement a
"download"-JSP, but
implemented that in a servlet, because there were many errors and caveats.

Greetings

output PDF via java.io.Writer

[Holger Prause]

Hello,

I am using Fop-0.20.2

Is it generally possible to output a pdf stream via a java.io.Writer object
? 

I know its better to use OutputStreams objects to output binary streams as
pdf,but i want to use a JSPWriter(in a TagLibrary Class) to output a Pdf
Stream so that i can use it as embedded pdf.

The following sourcode should do the the job


InputSource foInputSource = getInputSource();
//buffer fo outputStream
ByteArrayOutputStream foBufferStream = new ByteArrayOutputStream();
Driver driver = new Driver(foInputSource,foBufferStream);
driver.setRenderer(driver.RENDER_PDF);
//perform the fo rendering process
driver.run();

String foOutString = new String(foBufferStream.toByteArray());
//the writer reference is as reference to the JSPWriter which was passed as
Argument
writer.write(foOutString);
writer.flush();

The problem is that when i convert a ByteArrayOutputStream to a String ,
some characters are converted wrong.

For Example , the HEX 8d will be converted to HEX 3f , how can i avoid this
? What encoding do i have to use to avoid this ?

Thank you in advance,

Holger

Re: FOP Interfaces

[fred redf]

Hi Jeremias, and all other peoples here,

I would like to know where an arbitrary event has
occured during fop rendering. Let me give you a short
example:
i produce a *big* pdf with fop that should include
another pdf that was produced in another way (i my
case, it was produced by distiller from a word
document). That document should be included after a
... that is somewhere inside my
document.
Second example : i want to watermark some specific
pages according to the content that is on these pages.
For that purpose, i use iText.
So what i want is some kind of mechanism (for exemple
something like ) that
would enable me to get an Hashtable that contains the
page where this event has occured. After getting this
hashtable, i could run iText-based process to finish
my pdf. 
Is that more clear? Excuse me for my
not-that-good-english, i have also to admit that it
was not that clear in my head.
Thanks,

Fred.

Re: Example extension

[Keiron Liddle]

Hi,

It really depends on what type of extension you want to do.
This is an area that will change and become much easier in the future (in 
theory). Examples and help will be available for the new way of doing 
things.

Could you tell us what you want your extension to do so that we have more 
ideas on what type of extensions people are thinking about. Then we can 
work out how they should be handled if possible.

So to answer your question, there are some extensions but it really 
depends on what you want to do.

That's an XSLT extension, not a FOP extension. Right?

Right, I got that. And I appreciate your effort in this. My problem is
that I haven't yet seen the benefit of what you're trying to do. I
really think which we should have a least a third opinion on this.

I see. Are those three not rather static so it would make sense to place
the resource files with the classes and hard-code the validation code.
That would make it simpler. Or do you see a case where you need to use a
different validation file? If you code something like this I'd
apreciate if validation could be switched of for performance reasons.
