+ __footer__ - fast read and write access to the Exif, IPTC, and XMP metadata - of an image - -- -- -- --- an easy to use and extensively documented API
-- conversions of Exif and IPTC metadata to XMP and vice versa
-- a smart IPTC implementation that does not affect data that programs like Photoshop store - in the same image segment
-- Exif Makernote support: -
--
-
- Makernote tags can be read and written just like any other metadata -
- a sophisticated write algorithm avoids corrupting the Makernote -
- a simple interface to extract previews embedded in RAW images and Exif thumbnails
-- set and delete methods for Exif thumbnails
- +Examples: read Exif; - add, modify, delete Exif; - read IPTC; - set IPTC; - set XMP -
+ __bootstrap__ -Exiv2 is also a command line utility to
--
-
- print Exif, IPTC and XMP image metadata in different formats: Exif summary info, interpreted values, - or the plain data for each tag (a sample is here) -
- set, add and delete Exif, IPTC and XMP image metadata - from command line modify commands or command scripts -
- adjust the Exif timestamp (that's how it all started...) -
- rename Exif image files according to the Exif timestamp -
- extract, insert and delete Exif, IPTC and XMP metadata and JPEG comments -
- convert from Exif and IPTC to XMP properties and vice versa -
- extract previews from RAW images and thumbnails from the Exif metadata -
- insert and delete the thumbnail image embedded in the Exif metadata -
- print, set and delete the JPEG comment of JPEG images -
- fix the Exif ISO setting of picture taken with Canon and Nikon cameras -
Future plans include
--
-
- a unified metadata container -
- support for additional image formats -
- more Makernotes -
- to support CMake on all platforms -
The roadmap has details for the upcoming version.
