What is a good Java library for recording GPS metadata in JPEG (in EXIF)?

Question

I developed a Java application (Latipics) that displays photos with location information pulled from Google Latitude. I am using an open source library called Sanselan to read / write GPS coordinates from / to JPEG metadata.

It works mostly fine except that the Apple Preview (viewing in JPEG format in OS X) seems to misinterpret the GPS longitude link ( see the question for details ).

In any case, I am considering the possibility of removing Sanselan, but I cannot find a suitable replacement (remember that I need to write to metadata, and not just extract)

Thanks for the help.

Answer 1

Look at the OpenGTS source code ... you can get some advantage for your needs!

Answer 2

There is nothing better than ExifTool . It is also open source and very reliable. It is not written in java, but you have nothing to stop calling it from a java program.
