v2.7.1

• Add releases for Python3.10

v2.7.0

Add four features:

• Convert XMP tag of type LangAlt to a dict.
  Old version:

  >>> img.read_xmp()['Xmp.dc.title']
  'lang="x-default" test-中文-, lang="de-DE" Hallo, Welt'

  Now:

  >>> img.read_xmp()['Xmp.dc.title']
  {'lang="x-default"': 'test-中文-', 'lang="de-DE"': 'Hallo, Welt'}

• Add Image.get_mime_type()

  >>> img.get_mime_type()
  'image/jpeg'

• Add Image.get_access_mode()

  >>> img.get_access_mode()
  {'exif': 'read+write', 'iptc': 'read+write', 'xmp': 'read+write', 'comment': 'read+write'}

• Add registerNs()

  >>> img.modify_xmp({'Xmp.test.mytag1': 'Hello'})
  RuntimeError: No namespace info available for XMP prefix `test'
  >>> pyexiv2.registerNs('a namespace for test', 'Ns1')
  >>> img.modify_xmp({'Xmp.Ns1.mytag1': 'Hello'})
  >>> img.read_xmp()['Xmp.Ns1.mytag1']
  'Hello'

See the Tutorial for details.

v2.6.4

• Add two variables to get the version. ( Issue #80 )

  >>> import pyexiv2
  >>> pyexiv2.__version__
  '2.6.4'
  >>> pyexiv2.__exiv2_version__
  '0.27.4'

v2.6.3

• [Fix #74] Recompile the library on win_amd64 platform to support enableBMFF().

v2.6.2

Changes from v2.5.0:

• Add API:

  pyexiv2.Image.modify_raw_xmp()
  pyexiv2.enableBMFF()

  See the Tutorial for details.
• Change the way to delete a tag.
  Previously, it was assigning an empty string. For example:
  img.modify_xmp({"Xmp.xmp.Rating": ""})
  Now, assign None instead. For example:
  img.modify_xmp({"Xmp.xmp.Rating": None})
• Upgrade the exiv2 version used by pyexiv2 to 0.27.4.
  So compatibility with Linux and MacOS has changed. See the Tutorial for details.

v2.5.0

• Automatically convert some EXIF tags from UCS2 encoding to UTF-8 encoding.

  Affected Tags

  For example, the previous effect:

  >>> img.read_exif()['Exif.Image.XPKeywords']
  '116 0 101 0 115 0 116 0 0 0'

  The current effect:

  >>> img.read_exif()['Exif.Image.XPKeywords']
  'test\x00'

• Automatically convert some IPTC tags to List type, even if they do not have multiple values.

  Affected Tags

  For example, the previous effect:

  >>> img.modify_iptc({'Iptc.Application2.Keywords': 'tag1'})
  >>> img.read_iptc()['Iptc.Application2.Keywords']
  'tag1'

  The current effect:

  >>> img.read_iptc()['Iptc.Application2.Keywords']
  ['tag1']

v2.4.1

• Add APIs to handle comment embedded in images: read_comment(), modify_comment(), clear_comment()
• Add APIs to handle ICC Profile embedded in images: read_icc(), modify_icc(), clear_icc()
• Make test cases more rigorous.
• Make the wheel package for different platforms separately.

v2.3.2

• This is a patched version.
• Update documents
• Add compiled files for python3.9

v2.3.1

• This is a patched version.
• Add libexiv2.dylib to the .whl package.
  I forgot to do this in v2.3.0, which made it impossible to run pyexiv2 on MacOS.

v2.3.0

• This is a backward compatible version.
• Add class ImageData. It is used to open an image from bytes data.
• Enable running on MacOS.
