@ -22,8 +25,40 @@ From within Python, it is as simple as printing the Jp2k object, i.e. ::
>>> j = Jp2k(file)
>>> print(j)
The primary emphasis is on JP2 metadata, but it is possible to
display just raw codestream as well. This will display metadata present in the
codestream's main header only. ::
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>
<rdf:Description ns2:CreatorTool="glymur" rdf:about="" />
</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)]

Of particular focus is retrieval of metadata. Reading Exif UUIDs is supported,

some very limited support for reading JPX metadata. For instance,

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.
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
the signal (that most of the tests are actually passing), they've been
filtered out for now. There are also more skipped tests on Python 2.7
than on Python 3.3. The important point to remember is whether or not any test
errors are reported at the end.

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
* add read support or Exif UUIDs
* investigate using CFFI or cython instead of ctypes to wrap **openjp2**
* add read support for ICC profiles
