How do I...?
************
Get the code?
=============
Go to http://github.com/quintusdias/glymur
Display metadata?
=================
There are two ways. From the unix command line, the script **jp2dump** is
available. ::
$ jp2dump /path/to/glymur/installation/data/nemo.jp2
From within Python, it is as simple as printing the Jp2k object, i.e. ::
>>> import pkg_resources
>>> from glymur import Jp2k
>>> file = pkg_resources.resource_filename(glymur.__name__, "data/nemo.jp2")
>>> 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. ::
>>> print(j.get_codestream())
