Exiv2 C++ library features

Fast read and write access to the Exif, IPTC, and XMP metadata of an image
Easy to use and extensively documented C++ API

- Makernote tags can be read and written just like any other metadata
- Sophisticated write algorithm avoids corrupting the Makernote
Simple interface to extract previews embedded in RAW images and Exif thumbnails
Set and delete methods for Exif thumbnails
