I modified this code:

LOOK HERE

and I am attaching a program that reads latitude and longitude from a jpg file.
jar file for Libraries folder is attached.

Everything seems to be fine as long as the 360 degree jpg file is small (164 kb).
But the problem arises if the 360 degree jpg file is large (14 MB).
Could someone please advise me how to modify the code to read metadata from a large jpg file as well?
Or is there any other way to read the EXIF metadata (latitude, longitude ...) with B4J?

1. What happens with the large file?

2. It will probably behave the same, but please try it with the code I posted in that thread.

Erel, please look at the attached pictures and the ERROR report:

Looks like you are missing the xmpcore-x.x.xx.jar which contains the missing class (the x in the name is the version etc, get the latest one that works).

Thank you very much "Daestrum" now works fine with xmpcore-5.1.2.
Do not work with xmpcore-6.1.11.
