Exiv2 0.22

Exiv2 will allow you to print the Exif metadata of JPEG, TIFF and several RAW image formats as interpreted values, summary info, or the plain data for each tag. 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 · 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 accessed just like any other Exif metadata 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) · 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
