-Install
-------
+Installation
+------------

-Download OCRmyPDF here: https://github.com/fritz-hh/OCRmyPDF/releases
+Download OCRmyPDF here: https://github.com/jbarlow83/OCRmyPDF/releases

-You can install it within a virtual environment or system-wide. 
+You can install it to a Python virtual environment or system-wide. 

-To install the HEAD revision from sources in development mode::
+Installing the Docker container
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-   git clone -b master https://github.com/fritz-hh/OCRmyPDF.git
+For many users, installing the Docker container will be easier than installing all of OCRmyPDF's dependencies. For Windows, it is the only option.
+
+If you have `Docker <https://docs.docker.com/>`__ installed on your system, you can install
+a Docker container of the latest release.
+
+Follow the Docker installation instructions for your platform.  If you can run this command
+successfully, your system is ready to download and execute the image::
+
+   docker run hello-world
+   
+OCRmyPDF will use all available CPU cores.  By default, the VirtualBox machine instance on Windows and OS X has only a single CPU core enabled. Use the VirtualBox Manager to determine the name of your Docker container host, and then follow these optional steps to enable multiple CPUs::
+
+   # Optional
+   docker-machine stop "yourVM"
+   VBoxManage modifyvm "yourVM" --cpus 2  # or whatever number of core is desired
+   docker-machine start "yourVM"
+   eval $(docker-machine env "yourVM")
+
+Assuming you have a Docker engine running somewhere, you can run these commands to download
+the image::
+
+   docker pull jbarlow83/ocrmypdf
+
+Then tag it to give a more convenient name, just ocrmypdf::
+
+   docker tag jbarlow83/ocrmypdf ocrmypdf
+  
+You can then run using the command::
+
+   docker run ocrmypdf --help
+  
+To execute the OCRmyPDF on a local file, you must `provide a writable volume to the Docker image <https://docs.docker.com/userguide/dockervolumes/>`__, such as this in this template::
+
+   docker run -v "$(pwd):/home/docker" <other docker arguments>   ocrmypdf <your arguments to ocrmypdf>
+
+In this worked example, the current working directory contains an input file called ``test.pdf`` and the output will go to ``output.pdf``:: 
+
+   docker run -v "$(pwd):/home/docker"   ocrmypdf --skip-text test.pdf output.pdf
+
+Note that ``ocrmypdf`` has its own separate ``-v VERBOSITYLEVEL`` argument to control debug verbosity. All Docker arguments should before the ``ocrmypdf`` container name and all arguments to ``ocrmypdf`` should be listed after.
+
+Installing on Mac OS X
+~~~~~~~~~~~~~~~~~~~~~~
+
+These instructions probably work on all Mac OS X versions later than 10.7 (Lion). OCRmyPDF is known to work on Yosemite and El Capitan, and regularly tested on El Capitan.
+
+If it's not already present, `install Homebrew <http://brew.sh/>`__.
+
+Update Homebrew::
+
+   brew update
+   
+Install or upgrade the required Homebrew packages, if any are missing::
+
+   brew install libpng openjpeg jbig2dec     # image libraries
+   brew install qpdf
+   brew install ghostscript
+   brew install python3
+   brew install libxml2
+   brew install leptonica
+   brew install tesseract
+   
+It is also recommended that install Pillow and confirm it can read and write JPEG and PNG files::
+
+   pip3 install --upgrade pip
+   pip3 install --upgrade pillow
+
+Sometimes, the Python imaging library (Pillow) can end up being compiled and installed without support for JPEG and PNG files. (Arguably, this is an unfixed bug in Pillow's installer.) To confirm that Pillow is compiled correctly and can access JPEG and PNG files, try this command::
+
+   python3 -c "from PIL import Image; im = Image.new('1', (1, 1)); im.save('test.png'); im.save('test.jpg')"
+
+If you have trouble getting Pillow to access JPEG and PNG files, `review the installation instructions <https://pillow.readthedocs.org/installation.html>`__.
+
+You can then install OCRmyPDF from PyPI::
+
+   pip3 install ocrmypdf
+
+The command line program should now be available::
+
+   ocrmypdf --help
+
+Installing on Ubuntu 14.04 LTS
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Installing on Ubuntu 14.04 LTS (trusty) is more difficult than other options, because of certain bugs in Python package installation.
+
+Update apt-get::
+
+   sudo apt-get update
+   sudo apt-get upgrade
+   
+Install system dependencies::
+
+   sudo apt-get install \
+      zlib1g-dev \
+      libjpeg-dev \
+      ghostscript \
+      tesseract-ocr \
+      qpdf \
+      unpaper \
+      python3-pip \
+      python3-pil \
+      python3-pytest \
+      python3-reportlab
+
+If you wish install OCRmyPDF to the system Python, then install as follows (note this installs new packages
+into your system Python, which could interfere with other programs)::
+
+   sudo pip3 install ocrmypdf
+   
+If you wish to install OCRmyPDF to a virtual environment to isolate system Python from modified, you can
+follow these steps.  This includes a workaround `for a known, unresolved issue in Ubuntu 14.04's ensurepip
+package <http://www.thefourtheye.in/2014/12/Python-venv-problem-with-ensurepip-in-Ubuntu.html>`__::
+
+   sudo apt-get install python3-venv
+   python3 -m venv venv-ocrmypdf --without-pip
+   source venv-ocrmypdf/bin/activate
+   wget -O - -o /dev/null https://bootstrap.pypa.io/get-pip.py | python
+   deactivate
+   pyvenv --system-site-packages venv-ocrmypdf
+   source venv-ocrmypdf/bin/activate
+   pip install ocrmypdf
+
+Ubuntu 14.04 only installs ``unpaper`` version 0.4.2, which is not supported by OCRmyPDF because it is produces invalid output. This program is an optional dependency, and provides page deskewing and cleaning. See `Dockerfile <Dockerfile>`__ for an example of how to building unpaper 6.1 from source. If you choose to install unpaper later, OCRmyPDF will use the foremost version on the system PATH.
+
+      
+Installing HEAD revision from sources
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you have ``git`` and ``python3.4`` or ``python3.5`` installed, you can install from source. When the ``pip`` installer runs,
+it will alert you if dependencies are missing.
+
+First, clone the HEAD revision::
+
+   git clone -b master https://github.com/jbarlow83/OCRmyPDF.git
   cd OCRmyPDF
+
+To install the HEAD revision from sources::
+
+   pip3 install .
+
+Or, to install in `development mode <https://pythonhosted.org/setuptools/setuptools.html#development-mode>`__, 
+allowing customization of OCRmyPDF, use the ``-e`` flag::
+
   pip3 install -e .
   
-On certain Linux/UNIX platforms such as Ubuntu, you may need to use 
+On certain Linux distributions such as Ubuntu, you may need to use 
 run the install command as superuser::

-   sudo pip3 install -e .
+   sudo pip3 install [-e] .
   
 Note that this will alter your system's Python distribution. If you prefer 
 to not install as superuser, you can install the package in a Python virtual environment::

-   git clone -b master https://github.com/fritz-hh/OCRmyPDF.git
+   git clone -b master https://github.com/jbarlow83/OCRmyPDF.git
   pyvenv venv
   source venv/bin/activate
   cd OCRmyPDF
-   pip3 install -e .
+   pip3 install .

-If your platform does not have ``pip3``, make sure that Python 3.4+ and the `pip` 
-package are installed.
+However, ``ocrmypdf`` will only be accessible on the system PATH after
+you activate the virtual environment.

-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.

-    but WITHOUT ANY WARRANTY; without even the implied warranty of

-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:

-JHOVE - JSTOR/Harvard Object Validation Environment
-Copyright 2003-2012 by JSTOR and the President and Fellows of Harvard College
-JHOVE is made available under the GNU Lesser General Public License (LGPL;
-see the file LICENSE for details)
-
-Rev. 1.11, 2013-09-29
-
-JHOVE (the JSTOR/Harvard Object Validation Environment, pronounced "jhove")
-is an extensible software framework for performing format identification,
-validation, and characterization of digital objects.
-
-o Format identification is the process of determining the format to which a
-  digital object conforms: "I have a digital object; what format is it?"
-o Format validation is the process of determining the level of compliance of a
-  digital object to the specification for its purported format: "I have an
-  object purportedly of format F; is it?"
-o Format characterization is the process of determing the format-specific
-  significant properties of an object of a given format: "I have an object of
-  format F; what are its salient properties?"
-
-These actions are frequently necessary during routine operation of digital
-repositories and for digital preservation activities.
-
-The output from JHOVE is controlled by output handlers. JHOVE uses an
-extensible plug-in architecture; it can be configured at the time of its
-invocation to include whatever specific format modules and output handlers
-that are desired. The initial release of JHOVE includes modules for
-arbitrary byte streams, ASCII and UTF-8 encoded text, AIFF and WAVE audio,
-GIF, JPEG, JPEG 2000, TIFF, and PDF; and text and XML output handlers.
-
-The JHOVE project is a collaboration of JSTOR and the Harvard University
-Library.  Development of JHOVE was funded in part by the Andrew W. Mellon
-Foundation.  JHOVE is made available under the GNU Lesser General Public
-License (LGPL; see the file LICENSE for details).
-
-JHOVE is currently being maintained by indpendent developers.
-
-REQUIREMENTS
-
-1. Java J2SE 1.5
-(JHOVE was originally implemented using the Sun J2SE SDK 1.4.1 and has
-been tested to work with 1.5)
-
-2. If you would like to compile the JHOVE source code, then
-Apache Ant, a Java-based build tool <http://ant.apache.org/> is necessary.
-Note that the JAVA_HOME environment variable must be set appropriately for
-Ant to work properly.
-(JHOVE was implemented and tested using Ant 1.5.1.)

-INSTALLATION
-
-Edit the configuration file, jhove/conf/jhove.conf, and set the absolute
-pathname of the JHOVE home directory and the temporary directory (in which
-temporary files are created):
-
-    <jhoveHome>jhove-home-directory</jhoveHome>
-    <tempDirectory>temporary-directory</tempDirectory>
-
-The JHOVE home directory is the top-most directory in the distribution TAR
-or ZIP file.  On Unix systems, "/var/tmp" is an appropriate temporary
-directory; on Windows, "C:\Temp".  For example, if the distribution TAR
-file is disaggregated on a Unix system in the directory "/users/stephen/
-projects", then the configuration file should read:
-
-    <jhoveHome>/users/stephen/projects/jhove</jhoveHome>
-    <tempDirectory>/var/tmp</jhoveHome>
-
-In the JHOVE home directory, copy the JHOVE Bourne shell driver script
-template, "jhove.tmpl", to "jhove" (or the equivalent Windows shell 
-script, "jhove_bat.tmpl" to "jhove.bat"), and set the
-JHOVE home directory, Java home directory, and Java interpreter:
-
-    JHOVE_HOME=jhove-home-directory
-    JAVA_HOME=java-home-directory
-    JAVA=java-interpreter
-
-The JAVA_HOME property should provide the absolute pathname of the Java
-runtime or SDK installation; JAVA should provide the absolute pathname of the
-Java interpreter.  For example:
-
-    JHOVE_HOME=/users/stephen/projects/jhove
-    JAVA_HOME=/usr/local/j2re1.4.1_02
-    JAVA=$JAVA_HOME/bin/java
-
-In the DOS shell driver script, jhove.bat, the equivalent three
-variables are:
-
-    SET JHOVE_HOME=jhove-home-directory
-    SET JAVA_HOME=java-home-directory
-    SET JAVA=%JAVA_HOME%\bin\java
-
-For example:
-
-    SET JHOVE_HOME="C:\Program Files\jhove"
-    SET JAVA_HOME="C:\Program Files\java\j2re1.4.1_02"
-    SET JAVA=%JAVA_HOME%\bin\java
-
-The quotation marks are necessary because of the embedded space characters.
-On Windows platforms it may also be necessary to add the Java bin subdirectory
-to the System PATH environment variable:
-
-    PATH=C:\Program Files\java\j2re1.4.1_02\bin;...
-
-(For information on setting a Windows environment variable, consult your local
-documentation or system administrator.)
-
-USAGE
-
-    java Jhove [-c config] [-m module] [-h handler] [-e encoding] [-H handler]
-               [-o output] [-x saxclass] [-t tempdir] [-b bufsize]
-               [-l loglevel] [[-krs] dir-file-or-uri [...]]
-
-where -c config   Configuration file pathname
-      -m module   Module name
-      -h handler  Output handler name (defaults to TEXT)
-      -e encoding Character encoding used by output handler (defaults to UTF-8)
-      -H handler  About handler name
-      -o output   Output file pathname (defaults to standard output)
-      -x saxclass SAX parser class (defaults to J2SE default)
-      -t tempdir  Temporary directory in which to create temporary files
-      -b bufsize  Buffer size for buffered I/O (defaults to J2SE 1.4 default)
-      -l loglevel Logging level
-      -k          Calculate CRC32, MD5, and SHA-1 checksums
-      -r          Display raw data flags, not textual equivalents
-      -s          Format identification based on internal signatures only
-      dir-file-or-uri Directory or file pathname or URI of formated content
-                      stream
-
-All named modules and output handlers must be found on the Java CLASSPATH at
-the time of invocation.  The JHOVE driver script, jhove/jhove, automatically
-sets the CLASSPATH and invokes the Jhove main class:
-
-    jhove [-c config] [-m module] [-h handler] [-e encoding] [-H handler]
-          [-o output] [-x saxclass] [-t tempdir] [-b bufsize] [-l loglevel]
-          [[-krs] dir-file-or-uri [...]]
-
-The following additional programs are available, primarily for testing
-and debugging purposes.  They display a minimally processed, human-readable
-version of the contents of AIFF, GIF, JPEG, JPEG 2000, PDF, TIFF, and WAVE
-files:
-
-    java ADump  aiff-file
-    java GDump  gif-file
-    java JDump  jpeg-file
-    java J2Dump jpeg2000-file
-    java PDump  pdf-file
-    java TDump  tiff-file
-    java WDump  wave-file
-
-For convenience, the following driver scripts are also available:
-
-    adump  aiff-file
-    gdump  gif-file
-    jdump  jpeg-file
-    j2dump jpeg2000-file
-    pdump  pdf-file
-    tdump  tiff-file
-    wdump  wave-file
-
-The JHOVE Swing-based GUI interface can be invoked from a command shell from
-the jhove/bin sub-directory:
-
-    java -jar JhoveView.jar -c <configFile>
-
-where <configFile> is the pathname of the JHOVE configuration file.

-Rev. 2007-08-30
-
-Edit the configuration file, jhove.conf, and set the JHOVE home
-directory:
-
-    <jhoveHome>jhove-home-directory</jhoveHome>
-
-and temporary directory:
-
-    <tempDirectory>temporary-directory</tempDirectory>
-
-On most Unix systems, a reasonable temporary directory is "/var/tmp";
-on Windows, "C:\temp".
-
-The optional
-
-    <bufferSize>buffer-size</bufferSize>
-
-element defines the buffer size used for buffer I/O operations.
-
-The optional
-
-    <mixVersion>1.0</mixVersion>
-
-element specifies that the XML output handler should conform to the
-MIX 1.0 schema.  The default behavior is for handler output to conform
-to the MIX 0.2 schema.
-
-The optional
-
-    <sigBytes>n</sigBytes>
-
-element specifies that JHOVE modules will look for format signatures
-in the first <n> bytes of the file.  The default value is 1024.
-
-All class names must be fully qualified with their package name:
-
-    <module>
-      <class>fully-package-qualified-class-name</class>
-      <init>optional-initialization-argument</init>
-      <param>optional-invocation-argument</param>
-    </module>
-
-The optional <init> argument is passed to the module once at the time
-its class is instantiated.  See module-specific documentation for a
-description of any initialization options.
-
-The optional <param> argument is passed to the module every time it is
-invoked.  See module-specific documentation for a description of any
-invocation options.
-
-The order in which format modules are defined is important; when
-performing a format identification operation, JHOVE will search for a
-matching module in the order in which the modules are defined in the
-configuration file. In general, the modules for more generic formats
-should come later in the list. For example, the standard module ASCII
-should be defined before the UTF-8 module, since all ASCII objects
-are, by definition, UTF-8 objects, but not vice versa.

+For testing PDF/A generation failures, this wrapper calls ghostscript

+It assumes that it is called from a staged system PATH where the first

+file.  It will strip out the first item on path to invoke the real
+'gs'.  That is, it expects this when called

James R. Barlow	4f964a3c8a	Introduce --pdf-renderer auto Tess 3.03's has various quality problems like wrong DPI that are fixed in Tess 3.04. Idea here is to introduce an option to let OCRmyPDF select the rendering backend based on the options and system. However, we're not ready for tesseract as the main renderer. Setting pdf-renderer to tesseract does not pass all test cases, mainly the one where --tesseract-timeout is triggered, and some others.	2015-12-02 23:20:31 -08:00
James R. Barlow	df1fda7438	pageinfo: workaround PyPDF extractText limitations on hidden text It appears that extractText() does not find all text. At a glance it may be that Tesseract's PDF renderer generates a font and uses glyphs that map to different Unicode code points that PyPDF expects, so it discards the content and finds nothing. As a proxy in lieu of better PDF parsing, assume that a "GlyphLessFont" means there is a text there. I had previously found it does not work to check for the presence of a font on page.

James R. Barlow	9dad40b5a3	Major overhaul of the Dockerfile Switched from Ubuntu to debian:stretch because stretch has more recent versions of our binary packages and starts smaller. In particular, stretch has both pillow==2.9.0 and reportlab==3.2.0 available as system packages which saves the considerable hassle of install a toolchain. Instead, a pyvenv is set up with access to system's site-packages (note: needs two steps), making the binary-dependent packages available. Then the remaining packages are installed into the pyvenv with --no-cache-dir to avoid saving files. And there we are. Image is still very large (>500 MB), but programs like reportlab require font rendering capabilities so they pull in large portions of the Linux graphics stack. Not much will shrink that.	2015-08-20 01:25:31 -07:00

James R. Barlow	30072e0c70	Pillow sucks Far from being fluffy or friendly, Pillow silently allows installation of itself without support for major image types. Reportlab calls for pillow 2.4.0. On Ubuntu 14.04 LTS this will trigger an upgrade of pillow that will be built without JPEG or ZLIB so it is effectively neutered, and unfortunately Pillow will not detect this situation at install time and guide users to a resolution. Instead, you see nasty stack traces. So add a run-time check to ensure that Pillow is sane and capable of JPEG and PNG support since both may be used internally.	2015-08-16 00:54:03 -07:00

James R. Barlow	adf495e8cc	Remove JHOVE JHOVE is not an effective PDF/A validator, as detailed in this article: http://www.pdfa.org/2014/12/ensuring-long-term-access-pdf-validation-with-jhove/ In short, it's buggy. Out of 670 invalid PDF/A files in a test suite, it only flagged 5. It only looks for certain problems that Ghostscript generated PDFs are unlikely to have. So use qpdf as a final check for general ill-formed PDF problems since it is quite reliable. JHOVE 1 is no longer maintained. There's a JHOVE 2 but it has no PDF support. I also don't know if it's appropriate to bundle JHOVE, with an LGPL, under this project and its current license. Removing a dependency on Java is a huge win. A world with less Java is a world with less AbstractFactoryConstructorInterfaces.	2015-08-11 15:31:32 -07:00
James R. Barlow	9247ea00bf	Improve ruffus exception handling ruffus swallows the return code if the process of handling an exception we hit an error in ruffus' own code, which can happen.

James R.

In the process of properly handling return codes I discovered test_override_metadata triggers a NPE inside JHOVE probably due to the Unicode character checking. This could be specific to my JRE (1.6.0_65, Oracle) but it's probably JHOVE's fault. A valid PDF/A (per Acrobat) is still generated.	2015-08-11 00:17:02 -07:00
James R. Barlow	8d848284df	Fix code, test case: complain when GS fails to produce PDF/A Modified pipeline to fix regression and return the proper error code if we did not produce a PDF/A as expected. The wrapper forces the output to be PDF 1.3 which is not PDF/A compliant. The funny thing is that in some cases JHOVE incorrectly states that a file is PDF/A-1b compliant, well formed and valid, even when it is not according to Acrobat XI and is missing the PDF/A metadata marker, as far as I can tell. JHOVE may not be as beneficial as hoped.	2015-08-10 16:05:00 -07:00
James R. Barlow	8fe54d1a5c	Add new test case to check invalid PDF/A case It revealed a regression - return code not the same as v2.x for invalid PDF/A. It's also not easy to get the return code out of ruffus. Will need to tweak the final step of the pipeline.	2015-08-10 13:57:28 -07:00
