Exiv2 is a C++ image metadata manipulation library that makes reading and writing Exif, IPTC, and XMP image metadata easy. It provides full Exif makernote and thumbnail support. The Exiv2 command line utility prints Exif, IPTC and XMP metadata including Makernote tags in various formats, adjusts Exif timestamps, renames images according to the Exif timestamp, extracts and inserts Exif, IPTC, and XMP metadata and JPEG comments, or deletes the thumbnail or a specific type of metadata from an image. License: GNU General Public License (GPL) Changes: This release considerably extends the functionality for dealing with XMP. It includes conversion of Exif and IPTC to and from XMP, XMP sidecar files, and XMP pretty printing functionality. It also adds support for JPEG 2000 (JP2) and Photoshop (PSD) images, among other improvements and fixes.
