--------------------------------------
Summary: Imaging (Apache Sanselan) produces "odd offsets" in
(EXIF) metadata
Key: IMAGING-205
URL: https://issues.apache.org/jira/browse/IMAGING-205
Project: Commons Imaging
Issue Type: Bug
Components: imaging.*
Reporter: Joakim Knudsen
Priority: Critical
I'm using the "last stable version" of Apache Sanselan 0.97 in an Android
project (app). I have not upgraded to Commons Imaging yet, since the website
says there is no stable release yet. Meanwhile, there are bugs in Sanselan.
If I run the [sample code method
WriteExifMetadataExample.changeExifMetadata|http://svn.apache.org/repos/asf/commons/proper/sanselan/trunk/src/test/java/org/apache/sanselan/sampleUsage/WriteExifMetadataExample.java?p=820841]
on an image, which updates the Apterture and GPS tags, the resulting image
fails to validate (through Phil Harvey's ExifTool software):
{{> exiftool.exe -validate -error -warning -a "..\20171030_21481_COPY.jpg"
Validate : 19 Warnings (17 minor)

I need some advice on how to proceed here. Since Sanselan does not appear to do
what it should (even on very basic metadata editing), am I correct to assume
that the current version of Commons Imaging does a better job? :-)
