"""
Manipulation of EXIF, IPTC and XMP metadata and thumbnails embedded in images.
The ImageMetadata class provides read/write access to all the metadata and
the various thumbnails embedded in an image file such as JPEG and TIFF files.
Metadata is accessed through tag classes (ExifTag, IptcTag, XmpTag)
and the tag values are conveniently wrapped in python objects.
For example, a tag containing a date/time information for the image
(e.g. Exif.Photo.DateTimeOriginal) will be represented by a python
datetime.datetime object.
This module is a python layer on top of the low-level python binding of the
C++ library Exiv2, libexiv2python.
A typical use of this binding would be:
>>> import pyexiv2
>>> metadata = pyexiv2.ImageMetadata('test/smiley.jpg')
>>> metadata.read()
>>> print metadata.exif_keys
['Exif.Image.ImageDescription', 'Exif.Image.XResolution',
'Exif.Image.YResolution', 'Exif.Image.ResolutionUnit', 'Exif.Image.Software',
'Exif.Image.DateTime', 'Exif.Image.Artist', 'Exif.Image.Copyright',
'Exif.Image.ExifTag', 'Exif.Photo.Flash', 'Exif.Photo.PixelXDimension',
'Exif.Photo.PixelYDimension']
>>> print metadata['Exif.Image.DateTime'].value
2004-07-13 21:23:44
>>> import datetime
>>> metadata['Exif.Image.DateTime'].value = datetime.datetime.today()
>>> metadata.write()
