Andreas Lehmkühler commented on PDFBOX-3906:


- there is another build on 
[Travis-CI|https://travis-ci.org/apache/pdfbox-jbig2]
- there is an independent [github 
repository|https://github.com/apache/pdfbox-testfiles] to host the problematic 
testfiles
- the testfiles are downloaded if -Dskip-external-testfiles=false is used when 
running maven
- svngit2jira integration is enabled for both jbig2-github repos
- I've changed some last bits

[An issue|https://github.com/levigo/jbig2-imageio/issues/53] has been reported 
on our GitHub project. I would like to deal with the issue within the new 
structure. How are we going to manage issues related to the plugin? A new 
component on the PDFBOX project within this JIRA instance or using a separate 
JIRA project?

I was wondering where some of those files came from which are referenced in 
[several|http://www.ece.ubc.ca/spmg/jbig2/bitstreams/main.html] READMEs. I've 
contacted Dave Tompkins of the origin project at the University of British 
Columbia. And luckily he answered very fast, see my attached mail and his 
answer.
He grant us the right to use his files (042_\*.jb2 and amb\*.jb2). The content 
of those files should by covered by fair use. Especially the amb* files have a 
very bad resolution so that nobody would really use them for their content.

I've made all tests more lenient, so that they don't fail if a test file is 
missing. I've activated the tests for the jenkins job.

Now, lets see where to put those problematic test files and how to download them

worked fine.

bq. I've set up a simple build job (no tests, no deploy yet), see 
https://builds.apache.org/view/P/view/PDFBox/
I've activated the deploy mechanism and the first SNAPSHOT of the plugin is 
available now.

Re the test files without a compatible license, the simplest solution would be 
like this:
- have these files packed in a zip and hosted somewhere
- download them in some target subdir. To see how this works, see the pdfbox 
preflight subproject pom, the downloaded files are extracted in 
{{preflight/target/pdfs/Isartor testsuite}} and  
{{preflight/target/pdfs/Bavaria testsuite}}
- modify the code to download the files from there and not from the resource 
directory.

(Maybe it can also be downloaded into the resources dir, but I don't know if 
this is good practice...)

[jira] [Commented] (PDFBOX-3906) Contributing the JBig2 ImageIO Plugin to PDFBox​

Re the test files without a compatible license, the simplest solution would be 
like this:
- have these files packed in a zip and hosted somewhere
- download them in some target subdir. To see how this works, see the pdfbox 
preflight subproject pom, the downloaded files are extracted in 
{{preflight/target/pdfs/Isartor testsuite}} and  
{{preflight/target/pdfs/Bavaria testsuite}}
- modify the code to download the files from there and not from the resource 
directory.
(Maybe it can also be downloaded into the resources dir, but I don't know if 
this is good practice...)

Maybe you are too impatience? I can see the commits in PDFBOX-2852. Maybe there 
was just some delay?

I just did my first commit but it doesn't appear automatically in JIRA. I did a 
second one and used a setting in netbeans to update a JIRA task but that one 
didn't have any effect. Is there a way to get this like we have it with svn?

[~lehmi] thanks for all of your great work. I am sorry, that I am relatively

All new committers are onboard. I'm working on the git repo now.

The repo is available 
[here|https://git-wip-us.apache.org/repos/asf?p=pdfbox-jbig2.git;a=summary]. 
I've already submitted an initial version. I've simply copied the origin github 
repo, but I've omitted those test files which most likely must not be added. I 
haven't added the history as it might contain some problematic files.

TODOs:
- made some final adjustments
- setup a build job

I made a post clarifying that you're the Geschäftsführer of levigo solutions 
GmbH (because of the "I have no idea who 'hennejg' is" post) but it's probably 
stuck in moderation.

Thanks! I can see that there's some discussion about levigo and my role. Please

I've did some more research. Here is the current status of the testfiles:

+official and public records from the US+
- 002.jb2, 006.jb2
- 2012311000*.jb2 (11 files in total)

Representations of public U.S. government documents should be in the public 
domain and could be included 

+Lewinsky+
- 003.jb2

One page from an [official 
report|https://www.gpo.gov/fdsys/pkg/GPO-CDOC-106sdoc3/pdf/GPO-CDOC-106sdoc3-2.pdf]
 concerning the Lewinsky scandal. Should be in the public domain as well

+University of Britisch Columbia+
- 007.jb2, 042_*.jb2 (23 files in total): all files contain the same single 
page from the CCITT spec)
- amb_1.jb2, amb_2.jb2: a dithered low resolution image of Ally McBeal aka 
Callista Flockhart

We have the written permission from the generator of these files to use them. 
All files contain some copyrighted stuff. As we are not interested in the 
"visual content" at all and IMHO no one else might find a use case to benefit 
from the "visual content" itself, it shall be safe to claim fair use for that 
files.
I'm going to create a JIRA-ticket to clarify that.

+Constitution+
- 005.jb2

Seems to be 1 page from an older version of "The Constitution of the United 
States of America, Analyis and Interpretation"
[Here|https://www.gpo.gov/fdsys/pkg/GPO-CONAN-REV-2016/content-detail.html] is 
a more recent version

+ITU+
- sampledata_page1.jb2
- sampledata_page2.jb2
- sampledata_page3.jb2

Bitstreams which are reproduced as hex-dumps within the T.88 specification 
document. The ITU grants us a license to use them but with a non-commercial 
restriction.
-I'm going to create a JIRA-ticket to see if that is an issue or if we can make 
an exception as these files are used for tests only.- I'm afraid it doesn't 
matter how we use those files, we must not include them unless the ITU grants 
us to use them at least for tests without any restriction. 

+Libertarianism: A Primer+
- 004.jb2

2 pages from "Libertarianism: A Primer" by David Boaz, a copyrighted work from 
1997. We might claim fair use as well, as these are just 2 pages from a 300 
pages book and we are not interested in the content itself. I'm going to create 
a JIRA-ticket to clarify that.

In the end there might be some files which must not be included in our repo. We 
have to decide wether we host them somewhere outside like the the isator files 
or if we simply omit them

[~hennejg] Can you name the version of SHA you used to create the checksum? 
It's needed for the ip-clearance form

Andreas Lehmkühler commented on PDFBOX-3906:


I've did some more research. Here is the current status of the testfiles:

+official and public records from the US+
- 002.jb2, 006.jb2
- 2012311000*.jb2 (11 files in total)

Representations of public U.S. government documents should be in the public 
domain and could be included 

+Lewinsky+
- 003.jb2

One page from an [official 
report|https://www.gpo.gov/fdsys/pkg/GPO-CDOC-106sdoc3/pdf/GPO-CDOC-106sdoc3-2.pdf]
 concerning the Lewinsky scandal. Should be in the public domain as well

+University of Britisch Columbia+
- 007.jb2, 042_*.jb2 (23 files in total): all files contain the same single 
page from the CCITT spec)
- amb_1.jb2, amb_2.jb2: a dithered low resolution image of Ally McBeal aka 
Callista Flockhart

We have the written permission from the generator of these files to use them. 
All files contain some copyrighted stuff. As we are not interested in the 
"visual content" at all and IMHO no one else might find a use case to benefit 
from the "visual content" itself, it shall be safe to claim fair use for that 
files.
I'm going to create a JIRA-ticket to clarify that.

+Constitution+
- 005.jb2

Seems to be 1 page from an older version of "The Constitution of the United 
States of America, Analyis and Interpretation"
[Here|https://www.gpo.gov/fdsys/pkg/GPO-CONAN-REV-2016/content-detail.html] is 
a more recent version

+ITU+
- sampledata_page1.jb2
- sampledata_page2.jb2
- sampledata_page3.jb2

Bitstreams which are reproduced as hex-dumps within the T.88 specification 
document. The ITU grants us a license to use them but with a non-commercial 
restriction.
I'm going to create a JIRA-ticket to see if that is an issue or if we can make 
an exception as these files are used for tests only. 

+Libertarianism: A Primer+
- 004.jb2

2 pages from "Libertarianism: A Primer" by David Boaz, a copyrighted work from 
1997. We might claim fair use as well, as these are just 2 pages from a 300 
pages book and we are not interested in the content itself. I'm going to create 
a JIRA-ticket to clarify that.

In the end there might be some files which must not be included in our repo. We 
have to decide wether we host them somewhere outside like the the isator files 
or if we simply omit them

Cool! I wonder why I didn't come up with that. What is interesting is his hint 
that those files may exercise code paths that may not be that common but that 
are nevertheless out there.

{quote}
The content of those files should by covered by fair use. Especially the amb* 
files have a very bad resolution so that nobody would really use them for their 
content.
{quote}
But is fair use good enough for the ASF?

{quote}
We must not include any stuff which has a more restrictive license than the 
apache license. It wouldn't change anything to get a license which allows the 
commercial usage with a particular ASF project only.
{quote}
That's why I figured. So, try the exemption?

We can try to get an exception for some of the files, but I'm afraid we won't

some where else and download them while building the plugin. Or do I miss 
something?
{quote}
If so, I would suggest we try to get the exemption for the reference data 
streams from the specification and get rid of the dithered photo and the page 
from the specification. 

In terms of exercised code paths, it is important to have at least one halftone 
region, which would be covered by either the photo or the reference streams. 
However, should anything go wrong and need debugging, the reference streams are 
much easier to handle. Also, I presume the copyright situation is easier to 
deal with. The page from the specification, on the other hand, does not seem to 
bring something to the table, that isn't already covered elsewhere. (Maybe we 
were suffering from a pack rat syndrome here :-)

I could try to talk to the ISO liaison regarding the license. Are there some 
terms we could offer that would be acceptable and ASL compatible? Something 
like an agreement where the particular files can be used commercially, but only 
in conjunction with the particular ASF project?

[~hennejg] Those assumptions are not correct.

Copied from the [ASF release 
policy|http://www.apache.org/legal/release-policy.html]
{quote}
Every ASF release MUST contain one or more source packages, which MUST be 
sufficient for a user to build and test the release provided they have access 
to the appropriate platform and tools.
{quote}
Therefore those binary test files have to have a [suitable 
license|http://www.apache.org/legal/resolved]. 
- public domain shouldn't be a problem
- a non-commercial restriction is problematic
- files with an unknown license like the dithered photo or the page from the 
CCITT specification are problematic

I've searched the archives and found a lot discussions about that. In most 
cases the files in question must not be included. There are some rare cases 
with some very special exceptions.

We can try to get an exception for some of the files, but I'm afraid we won't 
get them for all of them. An alternative is to host the problematic test files 
some where else and download them while building the plugin. Or do I miss 
something?

Please note that there has been one addition since I created the export, namely 
a license notice file about the sample data pulled from the spec. I will create 
a new, hopefully final export once all the details have been sorted out. In 
particular, I see the following questions in need to be answered, ideally by 
ASF legal, since I don't readily have access to a U.S. copyright lawyer.

* Is is acceptable to have single reference files that do not become part of 
the distribution under a more restrictive license? This would be 
https://github.com/levigo/jbig2-imageio/commit/875dd85d8c077c72459ac75a5034cda7a4e3d931
* Can we use the other sample data under a U.S. government document public 
domain assumption or fair use terms (dithered photo of Callista Flockhart)?

The attached archive is already a revised version of that one we discussed on 
the dev@pdfbox. 

The text files mentioned on dev@pdfbox not having a license header now have 
one. 

Now there are only some binary files used as test resources left to be checked.

That was fast. I had a quick look and the non-commercial restriction seems 
problematic. We have to double check with legal first as these files are just 
testfiles and won't be redistributed.

The software-grant and another ICLA have been sent.
Some clarification about the software-grant might be necessary, though. 
The software-grant and the CCLA are signed by different legal entities 
(levigo holding/levigo solutions). This is due to the fact that 
contributors are employed by levigo solutions whereas the IP to be

In theory, yes, for example XnView supports JBIG2 via jbig2dec.exe. In
reality, support for the various cases covered in the test suite is
rather spotty: many of the images cannot be decoded with XnView. So,
strange as it might seem, I don't know of any reliable stand-alone JBIG2
viewer.

However, obviously those images can be decoded using the plugin. I've
attached PNG versions of them to a comment on the above issue:
https://github.com/levigo/jbig2-imageio/issues/48#issuecomment-324556311

Cool, I've already thought about converting them myself, but you were faster. 
Thanks. I'll have a look after the weekend as my time will be limited the next 
few days.

Thanks!


Losing this image would be bad, though, since it is the only halftone
region sample bitstream in there.

Maybe, we should think about a README which expains the origin of some/all of 
the test files
Yes, good idea. I already started documenting that in 
https://github.com/levigo/jbig2-imageio/issues/48. I'll throw that into 
a README once I'm done.




2. Files provided to us with the permission to use them for testing
purposes
201231100*.jb2 is the only case, seems to be a public U.S.
document anyway and therefore in the public domain. I have not
contacted the original provider of the files for the simple reason
that his or her e-mail address has been lost when the Googlecode site
went into archived state. >
3. Files with content so trivial that copyright should not be an
issue, i.e. fragments of bitstreams, isolated segments, trivial test
images

This isn't a question of copyright but of license and/or privacy.

The files in this category are sampledata_page(1,2,3).jb2. The content
is obviously not a matter of privacy. Regarding the license I am
currently asking around whether anyone still knows where this came from
(unfortunately we lost some very early RCS history from before we
open-sourced the component).
I just learned that those files contain sample bitstreams contained as 
hex-dumps within the standard. The standards are copyrighted by ITU/ISO 
and contain the following notice:


    All rights reserved. No part of this publication may be reproduced 
or utilized in any form or by any means, electronic or
    mechanical, including photocopying and microfilm, without 
permission in writing from the ITU.


Although I don't think that the authors and publishers intention was to 
prevent use of the sample bitstreams for testing purposes, the statement 
clearly covers them. WDYT?
I'm going to e-mail ITU wuth this question although I am not too 
optimistic about getting an answer some within this decade :-)

That's what I assumed as well, but upon re-checking, things no longer

Maybe you guys can help me with this problem or let me know how you

processing within the plugin or are they just a bunch of jbig2 files 
and could be replaced by others
JBIG2 isn't quite as simple as, say, PNG. There are several entropy 
coding options (Arithmetic/MQ, Huffman) several different segment types 
and several ways to maintain, refine and reference shape dictionaries. 
Therefore there a large number of code paths need to be covered in the 
tests. Since it is rather hard to generate all those possible 
combinations (no single encoder library will use all of them) the 
refrerence library provides (provided?) a convenient way of achieving 
decent test coverage.



The files seem to fall into three categories:
1. Files from the original test suite. While the copyright status of 
the file isn't problematic, the status of the content seems to be 
muddy in some cases.
   - Files containing representations of public U.S. government 
documents should be in the public domain: 
https://en.wikipedia.org/wiki/Copyright_status_of_work_by_the_U.S._government
   - The same applies to representations of U.S. patents: 
https://en.wikipedia.org/wiki/Copyright_on_the_content_of_patents_and_in_the_context_of_patent_prosecution 

   - 004.jb2 and 005.jb2 seem problematic but may be covered by some 
exemption.

   - amb.bmp no idea
amb.bmp seems problematic as it looks like a promo photo of Ally 
McBeal aka Callista Flockhart.
You seem to be more up to speed regarding TV characters. I certainly 
didn't recognise the person in the photo :-)

This isn't a question of copyright but of license and/or privacy.
The files in this category are sampledata_page(1,2,3).jb2. The content 
is obviously not a matter of privacy. Regarding the license I am 
currently asking around whether anyone still knows where this came from 
(unfortunately we lost some very early RCS history from before we 
open-sourced the component).

The following files don't have a license header:


Good catch. Tracked as https://github.com/levigo/jbig2-imageio/issues/46

What about the binary test files in src/test/resources/? I assume their 
license is cleared as well, isn't it?


That's what I assumed as well, but upon re-checking, things no longer seem to be 
so clear. I'm tracking this question as 
https://github.com/levigo/jbig2-imageio/issues/48

Maybe you guys can help me with this problem or let me know how you deal with 
it.

Is there any jbig2-viewer available?

Are these testfiles somehow special, do they trigger some special processing 
within the plugin or are they just a bunch of jbig2 files and could be replaced 
by others



The files seem to fall into three categories:
1. Files from the original test suite. While the copyright status of the file 
isn't problematic, the status of the content seems to be muddy in some cases.
   - Files containing representations of public U.S. government documents should 
be in the public domain: 
https://en.wikipedia.org/wiki/Copyright_status_of_work_by_the_U.S._government
   - The same applies to representations of U.S. patents: 
https://en.wikipedia.org/wiki/Copyright_on_the_content_of_patents_and_in_the_context_of_patent_prosecution 


   - 004.jb2 and 005.jb2 seem problematic but may be covered by some exemption.
   - amb.bmp no idea
amb.bmp seems problematic as it looks like a promo photo of Ally McBeal aka 
Callista Flockhart.

CCLA: done. Others: pending.

Thanks, once the SGA is on file I start with filing the ip-clearance template

Please create a JIRA ticket about adding your jbig2 plugin to PDFBox and 
attach a source tarball/zip and a SHA checksum to it, see PDFBOX-1056 which 
dealt with the integration of the PDF/A-validator some years ago.



Done.

One more heads up regarding IP vetting which you should be aware of: the patent 
situation surrounding JBIG2 is/was kind of muddy:
- all of the U.S. patents mentioned in Annex I of the specification have been 
expired be now
- as far as I can tell, none of the terms have been re-adjusted (I checked with 
the USPTO)

- both Japanese patens should be expired, but I haven't checked for extensions
- there may be other patens out there asserted after the completion of the 
standard, which I don't know about


In any case it should be clear that the transfer of the plugin source code to 
PDFBox does not include any rights to any of those or other patents!
The SGA grants a license for the code and any patents which are included. As 
those patents aren't included, everything should be ok.

Yes, I understand that. However, we are neither tied to the particular Maven 
coordinates nor to Maven central as a delivery platform.

Correct

And unless I am terribly confused about the ASL, there's nothing in the license 
preventing us from shipping our own release, unless we step on the toes of the 
official one in terms of Maven coordinates etc. On the other hand, building and 
shipping our own release is something we want to avoid as much as possible and 
thus something reserved for the rare exception.
Again correct, and yes it would be double work to do parallel releases, it shall 
be a last resort alternative.

Both strategies have their advantages/disadvantages. An independent source tree
gives us the following advantages:

- cut independent releases of both jbig2 and PDFBox
- cut a first jbig2 apache release right after the integration without waiting
for the 3.0 release of PDFBox

I'd go for an independent release. If we release inbetween we can
always update the dependency in pdfbox. And we don't add a timing
dependency for jbig2 on pdfbox where there isn't one.

+1

Could we potentially have jbig2 in a git repo. Might be easier as the
current active developers are used to working with git.

+1 :-)

Yes, that's correct. But versioning is dependent on the decision regarding the 
release strategy, anyway.

I'm not fluent enough in git or svn to love or hate them :-)

Getting the existing versioning in would be a bonus.

I just realized that we already have to git repos which where empty when

I'd go for an independent release. If we release inbetween we can
always update the dependency in pdfbox. And we don't add a timing
dependency for jbig2 on pdfbox where there isn't one.

Could we potentially have jbig2 in a git repo. Might be easier as the
current active developers are used to working with git.

Both strategies have their advantages/disadvantages. An independent source tree 
gives us the following advantages:


- cut independent releases of both jbig2 and PDFBox
- cut a first jbig2 apache release right after the integration without waiting 
for the 3.0 release of PDFBox

any kinks, missing stuff etc.

Well done, most of it is already looking quite good. Just some minor things

The following files don't have a license header:
  pom.xml
  release-notes.md

src/main/resources/META-INF/services/org.apache.pdfbox.jbig2.util.cache.CacheBridge

src/main/resources/META-INF/services/org.apache.pdfbox.jbig2.util.log.LoggerBridge
  src/main/resources/META-INF/services/javax.imageio.spi.ImageReaderSpi
  src/test/resources/META-INF/services/org.apache.pdfbox.jbig2.util.TestService
  README.md
  .travis.yml

What about the binary test files in src/test/resources/? I assume their license 
is cleared as well, isn't it?


In a previous message I mentioned the question of how we (levigo) can continue 
to contribute to or maintain the software once the migration has been completed. 
One option would certainly be to use GitHub with our (levigo's) repository 
becoming a downstream clone. Another option would be that the relevant 
developers become ASF committers. I myself are already one (ASF SVN id hennejg). 
If the plugin becomes a part of PDFBox the source as to be hosted on an ASF 
related server. As the PDFBox sources reside in a svn repository the new plugin 
will be added to that repository as well.



The other candidates are:

- Matthäus Mayer (mattha...@mayer.pub): initial lead developer of the component
- Sebastian Holder (s.hol...@levigo.de): current maintainer
- Carolin Köhler: (c.koeh...@levigo.de): current maintainer
Shouldn't be a problem. I'm planning to prepare a vote which will include a 
resolution to make the current maintainera a committer.


That's it for now, any help on how the next steps could look like would be 
greatly appreciated.

I'm going to start the IP-clearance process, more details to come.


Please provide the following paperwork:

- software-grant, see [1]
- an iCLA for all potential committers, which aren't apache committers yet, see 
 [2]
- a CCLA if necessary, see [3]

More details about the legal stuff can be found at [4]

[2] http://www.apache.org/licenses/icla.pdf
[3] http://www.apache.org/licenses/cla-corporate.pdf

Please create a JIRA ticket about adding your jbig2 plugin to PDFBox and attach 
a source tarball/zip and a SHA checksum to it, see PDFBOX-1056 which dealt with 
the integration of the PDF/A-validator some years ago.

PDFBox seems the more natural choice to me as, for example, levigo is very 
active in the PDF world, we've been a member of the PDF Association for a long 
time and feel "at home" in that context.

I've already started the process of getting approval from the relevant 
contributors.

Currently, there are two colleagues of mine who are familiar with the 
component. Additionally, there is one other developer who has left us, but who 
continues to contribute to the maintenance.

Fine, in the mean time, we'll continue to do our homework. I'll keep you posted 
about the progress.

Yes, diversity is an important aspect. I'm pretty sure that the code will 
attract other (pdfbox) developers once it is under the apache umbrella. The 
imaging [4] devs might be interested in the code as well.

I support your plan to integrate the plugin with pdfbox. We, the PDFbox PMC, 
have to discuss that topic first and have to perform a vote, but I guess this 
is just a formality.

Feel free to ask if there are any further questions.

Hello Jörg,

This is really great news. I am of course delighted because it would 
mean we can distribute it, thus having a better user experience for 
newbies. But Andreas knows more about what is to do to accept this 
contribution, such a thing was done in the past with PADAF (now 
Preflight) donated by atos worldline.

Hi all,


Apache PDFBox currently uses the JBig2 ImageIO-Plugin at 
https://github.com/levigo/jbig2-imageio as an optional component and recommends 
the use of it at https://pdfbox.apache.org/2.0/dependencies.html. I am writing 
this as a representative of the ISV levigo, the owner and publisher of this 
component. Besides being an open source component we use the component on our 
own software suite. Over the years we have invested significant time into it 
and have been maintaining it for many years so that I would consider its 
code-base reasonably mature and stable. However, we continue to address any 
bugs reported to us and have accepted several community-provided fixes.


The plugin in question is currently licensed under the GNU General Public 
License V3 with other licensing options available, including commercial 
licensing. Having PDFBox under the ASL and the plugin under a different license 
has long been a nuisance for PDFBox users which has deterred many users fron

is (IMHO) still the highest quality pure-Java open source decoder available.

We would like to change this situation by licensing the plugin under the ASL. 
At the same time, however, we think that it would make sense to move the code
