Subject [jira] [Commented] (IMAGING-205) Imaging (Apache Sanselan) produces "odd offsets" in (EXIF) metadata
Date Fri, 17 Nov 2017 22:22:00 GMT

    [ https://issues.apache.org/jira/browse/IMAGING-205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16257674#comment-16257674

Bruno P. Kinoshita commented on IMAGING-205:
--------------------------------------------

>Are you able to reproduce/verify the differences in the two jpeg files

Let me try it.

>Perhaps it is to be expected that different camera makers and different vendor OS will
produce differently structured JPEG metadata?

Yup, that seems to be quite normal. It increases the complexity for troubleshooting some issues,
so thanks heaps for attaching the examples from different cameras.

> 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|https://sno.phy.queensu.ca/~phil/exiftool/]):

> 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? :-)
