Java library for reading and writing IPTC metadata to JPEG and TIFF

Question

Does anyone know some opensource Java library for reading and writing IPTC metadata to JPEG and TIFF? Now I'm using Apache Sanselan. Unfortunately, it can only read IPTC, not write (http://commons.apache.org/sanselan/formatsupport.html).
Will be very grateful for your assistance.
Denis.

Answer 1

This seems to be quite a old question but following is some helpful info:

reading of metadata such as EXIF,IPTC..etc can be done using Apache Commons Imaging(Formerly Sanselan) or Metadata Extractor(by drew noaks).

writing of metadata can be done using Apache Commons Imaging using following classes:

EXIF - ExifRewriter (http://commons.apache.org/proper/commons-imaging/apidocs/org/apache/commons/imaging/formats/jpeg/exif/ExifRewriter.html)

IPTC - JpegIptcRewriter (http://commons.apache.org/proper/commons-imaging/apidocs/org/apache/commons/imaging/formats/jpeg/iptc/JpegIptcRewriter.html)

XMP - JpegXmpRewriter (http://commons.apache.org/proper/commons-imaging/apidocs/org/apache/commons/imaging/formats/jpeg/xmp/JpegXmpRewriter.html)

Answer 2

Take a look at IIM4J. Use IIMWriter to write IPTC IIM tags into (jpeg) images.

Answer 3

The Apache Commons Imaging (formerly sanselan) has added support for writing IPTC metadata in the svn repo code for their next release. I have verified that this is so in the latest trunk code checked out from svn repo. The code seems stable so I am hoping a release is not too far away. For my project this is good enough.
