@ section overview Exiv2 Overview
Exiv2 is a C + + library that provides
- read and write access to the Exif and Iptc IIM metadata of an image
through % Exiv2 keys and standard C + + iterators
- Exif MakerNote support :
- MakerNote tags can be accessed just like any other metadata
- a sophisticated write algorithm avoids corrupting the MakerNote :
< BR > & nbsp ; & nbsp ; 1 ) the MakerNote is not re - located if possible , and
< BR > & nbsp ; & nbsp ; 2 ) MakerNote IFD offsets are re - calculated if the MakerNote
needs to be moved ( for known IFD MakerNotes )
- new camera make / model specific MakerNotes can be added to the library
with minimum effort in OO - fashion ( by subclassing MakerNote or IfdMakerNote )
% Exiv2 comprises of a C + + library and 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
- a smart Iptc implementation that does not effect 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 :
< br > & nbsp ; & nbsp ; 1 ) the % MakerNote is not re - located if possible at all , and
< br > & nbsp ; & nbsp ; 2 ) % MakerNote % Ifd offsets are re - calculated if the
% MakerNote needs to be moved ( for known % Ifd % MakerNotes )
- new camera make / model specific % MakerNotes can be added to the library with
minimum effort in OO - fashion ( by subclassing % MakerNote or % IfdMakerNote )
- 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 )
- extract and delete methods for Exif thumbnails ( both , JPEG and TIFF thumbnails )
- Doxygen API documentation
- generic lower - level classes to access IFD ( Image File Directory ) data structures
% Exiv2 is also a command line program to
- print the Exif metadata of JPEG images ( as summary info , interpreted values , or
the plain data for each tag )
- print the Iptc metadata of JPEG images
- print the Jpeg comment of JPEG images
- adjust the Exif timestamp ( that ' s how it all started . . . )
- rename Exif image files according to the Exif timestamp
- extract Exif metadata , Iptc metadata and Jpeg comments from image files and
insert it again
- extract the thumbnail image embedded in the Exif metadata
- delete the thumbnail or the complete Exif metadata from an image
- complete API documentation ( by Doxygen )
- generic lower - level classes to access % Ifd ( % Image File Directory ) data
structures
