Bruno P. Kinoshita commented on IMAGING-205: -------------------------------------------- Had a bit more of time. So removed the code in the example that changes the the metadata (aperture, GPS). The changed code simply retrieved the TIFF metadata, and then called a code as below: {code:java} new ExifRewriter().updateExifMetadataLossless(jpegImageFile, os, outputSet); {code} And the output still presents the issue. So looks like we can focus on the ExifRewriter method call and onwards. > 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 > Assignee: Bruno P.
