Re: [iText-questions] Re gistration Black
Hi all, I bring up an old issue as I lately had to use this, i.e add registration black typographers marks in a PDF job I output using iText. (Though not an active forum poster, I am an avid forum reader. :) According to PDF1.7 Ref, page 266, section 4.5 Color Spaces it is: 1. The name parameter is a name object specifying the name of the colorant that this Separation color space is intended to represent (or one of the special names All or None; see below). Such colorant names are arbitrary, and there can be any number of them, subject to implementation limits. ... 2. The special colorant name All refers collectively to all colorants available on an output device, including those for the standard process colorants. When a Separation space with this colorant name is the current color space, painting operators apply tint values to all available colorants at once. This is useful for purposes such as painting registration targets in the same place on every separation. Such marks are typically painted as the last step in composing a page to ensure that they are not overwritten by subsequent painting operations. So the answer given by Leonard at the time is correct... On the other hand, using the iText API: setDefaultColorspace public void setDefaultColorspace(PdfName name, PdfObject obj) Sets the default colorspace. Parameters: name - the name of the colorspace. It can be PdfName.DEFAULTGRAY, PdfName.DEFAULTRGB or PdfName.DEFAULTCMYK obj - the colorspace. A null or PdfNull removes any colorspace with the same name In the following code line, PdfName can be SEPARATION along with the other API options cb.setDefaultColorspace(PdfName.SEPARATION, PdfObject obj); but ALL is not an option in iText API, either for a PdfName, or a PdfObject.. That said, my question remains: how exactly one defines/uses marks as registration black appearing in all color plates, using iText? On the occasion a great Thanks to Bruno for his excellent work and the new book under construction! Thanks all George Leonard Rosenthol wrote: Exactly, George. The colorspace is Separation, and the name is All. Leonard On Apr 18, 2008, at 1:03 PM, George Bilalis wrote: Hi all, Registration Black has to register on all separated plates of a print job.

Re: [iText-questions] PdfStamper modifies XmpMetadata
Thanks. Your XMP (in Source.pdf) is invalid - so it's probably a good thing that iText attempts to rewrite it, as it has fixed at least the biggest problem. However, other problems remain. XMP is a subset of RDF which is a specific XML grammar. Your XML isn't compliant with the rules of RDF.

Re: [iText-questions] Problem in nesting of lists in RTF?
I believe a related bug has been filed:
http://sourceforge.net/tracker/?func=detailaid=2802486group_id=15255atid=115255
They're using the HtmlWorker, but I'm guessing the root cause is just
in the RTF generation. I see the same behavior that you are in one of
our test cases. However, we're not currently using sub lists in our
product (so I haven't looked at fixing it myself, yet). If you're
able to fix the source code, and submit a patch - well, that would be
awesome. :)
I have a couple of similar outstanding patches - maybe when the
project goes into incubator mode, they'll get merged in.
btw - thanks to Bruno, Howard, et al, the RTF support does go a pretty
long way. And if you're willing to fix a couple things here and there
for your specific uses - you can do a lot with it.
Cheers,

The root object, 69, is among those AWOL from the xref... leading to the
error you're getting.
WHY is it missing? I'm not sure. The xref looks like one you'd find as a
result of a stamper in append mode, tacked onto the original PDF, but
the rest of the file looks like it should have a single xref. The trailer
makes no mention of a previous xref or xref stream.
You're not explicitly setting the stamper to use append mode, so it will
only go into that mode, IIRC, if forced by a signature. (And I don't see
anything in the source that backs that up either, so now I'm Really
Confused)
Is this a single threaded environment? (he asked, grasping at straws)

if i try to read the corrupted file using pdfreader i get

consistant. I am able to water mark the same original file
2nd time using
the same code. So it's like randomly some file is not fully written.
i am gussing this is because the pdfstamper is closing the

earlier than it should for some reason. However what i want
to confirm is
that my understanding that the probelm is infact the memory
stream is right
or not?. Because i have implmented alternative technique to
compltely avoid

to have fixed the issue in dev. But still need to get

Hi
Sorry resending this post as i was not registered user earlier.
i am using latest iTextSharp library to edit the pdf

found that i can
add a annotation to the pdf document and then set the flags to
annotation.Flags = PdfAnnotation.FLAGS_NOVIEW |
PdfAnnotation.FLAGS_INVISIBLE | PdfAnnotation.FLAGS_HIDDEN;
to make it
invisible.
so this is working fine as expected 90% of the time.
Remaning 10 % of the
time i get an error when i open the document after adding
the annotation
it says Root object is invalid or missing

Attached is the corrupt file.
if i try to read the corrupted file using pdfreader i get the error
message
saying start ref not found. But the issue is that problem is not
consistant. I am able to water mark the same original file 2nd time using
the same code. So it's like randomly some file is not fully written.
i am gussing this is because the pdfstamper is closing the memory stream
earlier than it should for some reason. However what i want to confirm is
that my understanding that the probelm is infact the memory stream is
right
or not?. Because i have implmented alternative technique to compltely
avoid
memory stream and pdf stamper but use pdfwriter and file stream which seem
to have fixed the issue in dev. But still need to get response from a
heavy
testing team. Any light thrwon on this subject will be of great help to
me.

Re: [iText-questions] Losing dynamic links after generating TOC .
That iterate through each page and import it into the Document object is where you're going wrong. While PdfCopy knows how to preserve links, the regular Document/PdfWriter combo does not. I suspect you'll have to write your TOC document out as a seperate file (or memory stream), then use PdfCopy again. --Mark Storer Senior Software Engineer Cardiff.com #include disclaimer typedef std::DisclaimerCardiff DisCard; -Original Message- From: Digumarti, Swapna [mailto:swapna.diguma...@capgemini.com] Sent: Monday, November 16, 2009 8:59 PM To: iText-questions@lists.sourceforge.net Subject: [iText-questions] Losing dynamic links after generating TOC . Hi, I am facing the following issue while merging two pdfs and then creating a toc. The requirement is that I have to merge 2 existing pdfs(provided by client which may have internal/External links). After these two pdf's are merged(I have used PdfCopy), I have to add a toc to it. The toc will have titles which are hardcoded,but the page number is generated dynamically. I start off by creating the toc which returns me a Document object. Then I iterate thru the pages of the merged document and import each page into the Document object. In doing so,I am losing any dynamic external/internal url present in the initial 2 documents that I had merged. PS:The links were not lost after the merge, they were lost only after the toc was added. PFA the two merged pdfs along with the java main class and the output pdf. Thanks in advance for the help.

Hi Paulo,
Thank you. Sorry if i am missing something. so where is the
SVN repository
url to check out the code for multi threading? Thanks

Attached is the corrupt file.
if i try to read the corrupted file using pdfreader i get the error
message
saying start ref not found. But the issue is that problem is not
consistant. I am able to water mark the same original file
2nd time using
the same code. So it's like randomly some file is not fully written.
i am gussing this is because the pdfstamper is closing the
memory stream
earlier than it should for some reason. However what i want
to confirm is
that my understanding that the probelm is infact the memory
stream is
right
or not?. Because i have implmented alternative technique to
compltely
avoid
memory stream and pdf stamper but use pdfwriter and file
stream which seem
to have fixed the issue in dev.

Atached are files an also search the keywords list: http://1t3xt.info/tutorials/keywords/ I haven't been following this in detail but, and someone who use itext please correct me if wrong, generally the document processing is a single threaded operation unless you try to split up tasks to avoid waiting for IO etc. As I understood the OP, the problem seems to relate to using one JVM to process separate pages concurrently. Asynchronous and indpenedent requests come in and some how they get intermingled. This would seem difficult as you would think each request sets up its own objects but things like static variables or collections would be suspects- often these are caches or general junk bins based on hashtables or other collections. Is the above essentially right? If so, I would also mention one more philosophical note related to Java. Many base classes are synchronized so everyone thinks they are thread safe but of course safe depends on what you are trying to do. Apps generally find blanket class synchonization useless and an invitations for derived classes to create deadlock. So, further, you would hope that itext is NOT designed to be thread safe unless that idea can be reasonably defined for everyone who wants to use it. Also, everything else in your post just suggests it is a threading problem- unreproducible, confusing, or logically impossible results usually are related to timing. In Java anyway, where you don't have the freedom to corrupt memory, they almost always are.

Re: [iText-questions] RTF - problem in cross references
Hi Mark, On many posting I read that internal links are not supported in RtfWriter2 but could not find any explanation why. Is this a limitation imposed by the RTF definition? If not is this feature planed on the road map? Thanks, Alain -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
