Exiv2 0.10 - Command line tool to access EXIF data in image files.

Exiv2 is a command line utility to access image metadata. Exiv2 is free software.

The Exiv2 library provides

* full read and write access to the Exif and IPTC metadata of an image through Exiv2 keys and standard C++ iterators (Example1, Example2, Example3, Example4) * a smart IPTC implementation that does not affect data that programs like Photoshop store in the same image segment * Exif MakerNote support: o MakerNote tags can be accessed just like any other Exif metadata o a sophisticated write algorithm avoids corrupting the MakerNote: 1) the MakerNote is not re-located if possible at all, and 2) MakerNote Ifd offsets are re-calculated if the MakerNote needs to be moved (for known Ifd MakerNotes) * extract and delete methods for Exif thumbnails (both, JPEG and TIFF thumbnails) * set methods for Exif thumbnails (JPEG only, TIFF thumbnails can be set from individual tags) * complete API documentation (by Doxygen)

Exiv2 is a command line utility to

* print the Exif metadata of JPEG, TIFF and several RAW image formats as summary info, interpreted values, or the plain data for each tag (a sample is here) * print the IPTC metadata of JPEG images * print, set and delete the JPEG comment of JPEG images * set, add and delete Exif and IPTC metadata of JPEG images * adjust the Exif timestamp (that's how it all started...) * rename Exif image files according to the Exif timestamp * extract, insert and delete Exif metadata, IPTC metadata and JPEG comments * extract, insert and delete the thumbnail image embedded in the Exif metadata * fix the Exif ISO setting of picture taken with Nikon cameras.
