[jira] [Updated] (TIKA-915) Image geodata being rounded to integers
[ https://issues.apache.org/jira/browse/TIKA-915?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ray Gauss II updated TIKA-915:
------------------------------
Attachment: problem_jpeg_geo_test.diff
testJPEG_GEO_2.jpg
Attached is a patch which includes a test which demonstrates the failure and a smaller version of the example file.
Unfortunately the patch also contains some of the changes from TIKA-859 in the test class so you can ignore those.
Also, the grant of license only applies to the patch, license to use the image was obtained by Nick.

> This was initially reported as an Alfresco issue, https://issues.alfresco.com/jira/browse/ALF-13004, but is actually a Tika problem. It seems that for some images, the geo metadata is being incorrectly rounded to an integer:
> $ tika --metadata 2012-02-19\ 16.43.29.jpg | grep --text geo
> geo:lat: 51.0
> geo:long: -1.0
> The image was actually taken at (as extracted by exiftool)
> $ exiftool 2012-02-19\ 16.43.29.jpg | grep GPS
> ....
> GPS Altitude : 295 m Above Sea Level
> GPS Date/Time : 2012:02:20 16:44:22Z
> GPS Latitude : 51 deg 34' 32.74" N
> GPS Longitude : 1 deg 34' 4.39" W
> GPS Position : 51 deg 34' 32.74" N, 1 deg 34' 4.39" W
> The sample file for this example is available at <https://issues.alfresco.com/jira/secure/attachment/29236/2012-02-19+16.43.29.jpg>. We do have the OK to use the photo in a test suite, but it's possibly a bit big as-is so we may need to resize it whilst preserving the exif data for a unit test.
