=========================================
glymur: a Python interface for JPEG 2000
=========================================
**glymur** contains a Python interface to the OpenJPEG library
which allows linux and mac users to read and write JPEG 2000 files. For more
information about OpenJPEG, please consult http://www.openjpeg.org. **glymur**
should be considered to be alpha-quality software.
**glymur** tries to support reading (including all metadata) and writing of
JP2 and J2C files. Writing J2C/JP2 files is currently limited to images that
can fit in memory, however.
There is some very limited support for reading JPX
metadata. For instance, **asoc** and **labl** boxes are recognized, so GMLJP2
metadata can be retrieved from such JPX files.
------------
Requirements
------------
**glymur** works on Python 2.7 and 3.3. Python 3.3 is strongly recommended.
OpenJPEG
========
OpenJPEG must be built as a shared library. In addition, you
currently must compile OpenJPEG from the developmental source that
you can retrieve via subversion. As of this time of writing, svn
revision 2345 works. In addition, you should also retrieve their test data, as
you will need it when running **glymur**'s test suite.
Earlier versions of OpenJPEG through the 2.0 official release are not supported.
Be sure to have the following ports/RPMs/debs installed.
* gcc
* gcc-c++
* cmake
You should build OpenJPEG with testing turned on. Consult the OpenJPEG
documentation on how to do this. If you use linux, make sure that you
have the following development packages installed
* zlib-devel
* png-devel
* libtiff-devel
* lcms2-devel
OS
==
Mac OS X
--------
All the necessary packages are available to use **glymur** with Python 3.3 via
MacPorts. A minimal set of ports includes
* python33
* py33-numpy
* py33-distribute
To run all the testing, one of the following combinations of ports must
additionally be installed:
* py33-scikit-image and either py33-Pillow or freeimage
* py33-matplotlib and py33-Pillow
Linux
-----
Fedora 18
'''''''''
Fedora 18 ships with Python 3.3, so all the necessary RPMs are available to
meet the minimal set of requirements.
* python3
* python3-numpy
* python3-setuptools
* python3-matplotlib (for running tests)
* python3-matplotlib-tk (or whichever matplotlib backend you prefer)
A few tests still will not run, however, unless one of the following
combinations of RPMs / Python packages is installed.
* scikit-image and either Pillow or freeimage
* matplotlib and Pillow
The 2nd route is probably the easiest, so go ahead and install **Pillow**
via **pip** since **Pillow** is not yet available in Fedora 18 default
repositories::
$ yum install python3-devel # pip needs this in order to compile Pillow
$ yum install python3-pip # First one must install pip of course!
$ pip-python3 install Pillow --user
$ export PYTHONPATH=$HOME/.local/lib/python3.3/site-packages:$PYTHONPATH
Fedora 17
'''''''''
Fedora 17 ships with Python 3.2 and 2.7, so these steps detail working with
2.7.
Required RPMs include::
* python
* python-mock
* python-pip
* python-setuptools
* numpy
In addition, you must install **contextlib2** via pip.
A few tests still will not run, however, unless one of the following
combinations of RPMs / Python packages is installed.
* scikit-image and either Pillow or freeimage
* matplotlib and Pillow
**scikit-image** is not available in the Fedora 17 default repositories, but
it may be installed via **pip**::
$ yum install Cython # pip needs this in order to compile scikit-image
$ yum install python-devel # pip needs this in order to compile scikit-image
$ yum install freeimage # scikit-image uses this as a backend
$ yum install scipy # needed by scikit-image
$ pip-python install scikit-image --user
$ pip-python install contextlib2 --user
$ export PYTHONPATH=$HOME/.local/lib/python2.7/site-packages:$PYTHONPATH
Windows
-------
Not currently supported.
------------------------------------
Installation, Testing, Configuration
------------------------------------
From this point forward, python3 will be referred to as just "python".
Installation
============
In addition to merely installing **glymur**, you should adjust your **$PATH**
environment variable in order to be able to use the **jp2dump** script from
the unix command line.
::
$ python setup.py install --prefix=/install/path
$ export PYTHONPATH=/install/path/lib/python3.3/site-packages
$ export PATH=/install/path/bin:$PATH
Configuration
=============
glymur uses **ctypes** (for the moment) to access the openjp2 library, and
because **ctypes** access libraries in a platform-dependent manner, it is
recommended that you create a configuration file to help glymur properly find
the openjp2 library. You may create the configuration file as follows::
$ mkdir ~/.glymur
$ cd ~/.glymur
$ cat > glymurrc << EOF
> [library]
> openjp2: /opt/openjp2-svn/lib/libopenjp2.so
> EOF
That assumes, of course, that you've installed OpenJPEG into /opt/openjp2-svn.
Testing
=======
In order to run all of the test suite, you will first need the OpenJPEG test
data that you previously retrieved.
Then you should set the **OPJ_DATA_ROOT** environment variable to
point to this directory, e.g.::
$ cd /somewhere/outside/the/glymur/unpacking/directory
$ svn co http://openjpeg.googlecode.com/svn/data
$ export OPJ_DATA_ROOT=`pwd`/data
The test suite may then be run with::
$ cd /back/to/glymur/unpacking/directory
$ python -m unittest discover
At the moment, the development version of the library prints quite a few
warnings to stderr, which you may ignore. There are also more skipped tests
on Python 2.7 than on Python 3.3. The important thing will be whether
or not any test errors are reported at the end.

>>> j = Jp2k(file)
>>> print(j)
The primary emphasis is on JP2 metadata, but it is possible to
display raw codestream as well::
This prints the metadata found in the JP2 boxes, but in the case of the
codestream box, only the main header is printed. It is possible to print
**only** the codestream information as well, i.e. ::
>>> print(j.get_codestream())
Work with XMP UUIDs?
====================
The example JP2 file shipped with glymur has an XMP UUID::
>>> import pkg_resources
>>> from glymur import Jp2k
>>> file = pkg_resources.resource_filename(glymur.__name__, "data/nemo.jp2")
>>> j = Jp2k(file)
>>> print(j.box[4])
UUID Box (uuid) @ (715, 2412)
UUID: be7acfcb-97a9-42e8-9c71-999491e3afac (XMP)
UUID Data:
<ns0:xmpmeta xmlns:ns0="adobe:ns:meta/" xmlns:ns2="http://ns.adobe.com/xap/1.0/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" ns0:xmptk="XMP Core 4.4.0-Exiv2">

</rdf:RDF>
</ns0:xmpmeta>
Since the UUID data in this case is returned as an ElementTree Element, one can
use ElementTree to access the data. For example, to extract the
**CreatorTool** attribute value, the following would work::
>>> xmp = j.box[4].data
>>> ns0 = '{http://www.w3.org/1999/02/22-rdf-syntax-ns#}'
>>> ns1 = '{http://ns.adobe.com/xap/1.0/}'
>>> name = '{0}RDF/{0}Description'.format(ns0)
>>> elt = xmp.find(name)
>>> elt
<Element '{http://www.w3.org/1999/02/22-rdf-syntax-ns#}Description' at 0xb4baa93c>
>>> elt.attrib['{0}CreatorTool'.format(ns1)]

Quite a few tests are currently skipped. These include tests whose
OpenJPEG counterparts are already failing, and others which do pass but
still produce heaps of output on stderr. Rather than let this swamp

filtered out for now. There are also more skipped tests on Python 2.7

Roadmap
-------
Here's an incomplete list of what I'd like to focus on in the near future.
* continue to monitor upstream changes in the openjp2 library
* investigate using CFFI or cython instead of ctypes to wrap openjp2
* eventually expose the openjp2 API
* add metadata support for ICC profiles
* investigate JPIP
