pyexiv2

Read/Write metadata of digital image, including EXIF, IPTC, XMP.

• install: pip install pyexiv2
• source code on github

Features

• Runs on C++ API of Exiv2.
• Supports running on Linux 64bit.
• Supports running on Windows 64bit, with Python3(64bit).
• Supports various metadata
• Supports various image formats
• Supports Unicode characters that contained in image paths and data.

Usage

• read metadata :

  >>> from pyexiv2 import Image
  >>> i = Image("tests/1.jpg")
  >>> i.read_exif()
  {'Exif.Image.DateTime': '2019:06:23 19:45:17', 'Exif.Image.Artist': 'TEST', 'Exif.Image.Rating': '4', ...}
  >>> i.read_iptc()
  {'Iptc.Envelope.CharacterSet': '\x1b%G', 'Iptc.Application2.ObjectName': 'TEST', 'Iptc.Application2.Keywords': 'TEST', ...}
  >>> i.read_xmp()
  {'Xmp.dc.format': 'image/jpeg', 'Xmp.dc.rights': 'lang="x-default" TEST', 'Xmp.dc.subject': 'TEST', ...}

• modify metadata :

  >>> # prepare the XMP data you want to modify
  >>> _dict = {"Xmp.xmp.CreateDate": "2019-06-23T19:45:17.834",   # this will overwrite its original value, or add it if it doesn't exist
  ...          "Xmp.xmp.Rating": ""}  # set an empty str explicitly to delete the datum
  >>> i.modify_xmp(_dict)
  >>> # check the result
  >>> xmp_dict = i.read_xmp()
  >>> xmp_dict["Xmp.xmp.CreateDate"]
  '2019-06-23T19:45:17.834'           # it has been set
  >>> xmp_dict["Xmp.xmp.Rating"]
  KeyError: 'Xmp.xmp.Rating'          # it has been deleted

  • Use i.modify_exif() and i.modify_iptc() in the same way.

• In short, please call the public methods of class pyexiv2.Image :

  i = Image("tests/1.jpg")
  i.read_exif()
  i.read_iptc()
  i.read_xmp()
  i.read_all()
  i.modify_exif({"Exif.Image.ImageDescription": "test",...})
  i.modify_iptc({"Iptc.Application2.ObjectName": "test",...})
  i.modify_xmp({"Xmp.xmp.CreateDate": "2019-06-23T19:45:17.834",...})
  i.modify_all({"EXIF":{...}, "IPTC":{...}, "XMP":{...}})
  i.clear_exif()
  i.clear_iptc()
  i.clear_xmp()
  i.clear_all()
