I have looked at many of the other similar questions but none of them seem to have a precise answer.
I'm working on an Android app that works with a lot of images. I am looking to add information to images by editing the value of their IPTC keyword tag (or other appropriate tags). I am using Metadata Extractor for reading metadata but this library doesn't support writing metadata.
I have looked at Apache Sanselan which doesn't seem to be appropriate because it has heavy dependency on java.awt
(which is not available in Android). I'm aware of Imagero but I have not used it yet in the hope of finding a better open source library.
Has anyone come across such a library? I prefer it to be open source but even commercial suggestions would be appreciated.
Thanks in advance.
