---------------------------------------- Glymur: a Python interface for JPEG 2000 ---------------------------------------- **Glymur** is an interface to the OpenJPEG library which allows one to read and write JPEG 2000 files from within Python. Glymur supports both reading and writing of JPEG 2000 images. Writing JPEG 2000 images is currently limited to images that can fit in memory, however. Of particular focus is retrieval of metadata. Reading Exif UUIDs is supported, as is reading XMP UUIDs as the XMP data packet is just XML. 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. Glymur works on Python 2.6, 2.7, and 3.3. OpenJPEG Installation ===================== Glymur will read JPEG 2000 images with versions 1.3, 1.4, 1.5, 2.0, and the trunk/development version of OpenJPEG. Writing images is only supported with the 2.0 series, however, and the trunk/development version is strongly recommended. For more information about OpenJPEG, please consult http://www.openjpeg.org. If you use MacPorts on the mac or if you have a sufficiently recent version of Linux, your package manager should already provide you with a version of OpenJPEG 1.X with which glymur can already use for read-only purposes. If your platform is windows, I suggest using the windows installers provided to you by the OpenJPEG folks at https://code.google.com/p/openjpeg/downloads/list . Glymur Installation =================== You can retrieve the source for Glymur from either of * https://pypi.python.org/pypi/Glymur/ (stable releases) * http://github.com/quintusdias/glymur (bleeding edge) but you should also be able to install Glymur via pip :: $ pip install glymur This will install the **jp2dump** script that can be used from the unix command line, so you should adjust your **$PATH** to take advantage of it. For example, if you install with pip's `--user` option on linux :: $ export PYTHONPATH=$HOME/.local/lib/python3.3/site-packages $ export PATH=$HOME/.local/bin:$PATH You can run the tests from within python as follows:: >>> import glymur >>> glymur.runtests() Many tests are currently skipped; in fact most of them are skipped if you are relying on OpenJPEG 1.X. The important thing, though, is whether or not any tests fail.
