python3-exiv2

py3exiv2 allows you to use the lib exiv2 into your Python 3 code.

exiv2 is a C++ library designed to handle the EXIF, IPTC and XMP image metadata.

With py3exiv2 you can read and write all standard metadata, create your own XMP namespace or extract the thumbnail embedded in image file.

py3exiv2 is the Python 3 version of pyexiv2 written for Python 2, if you're already using pyexiv2, you should be able to re-use your code with py3exiv2.

A minimal example:

>>> import pyexiv2
>>> data = pyexiv2.metadata.ImageMetadata('lena.jpg')
>>> data.read()
>>> for key in data.exif_keys:
...     tag = data[key]
...     print(' %-40s%s' %(key, tag.value))
...
