[jira] [Resolved] (SANSELAN-13) Problem loading JPEG metada
[ https://issues.apache.org/jira/browse/SANSELAN-13?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Damjan Jovanovic resolved SANSELAN-13.
--------------------------------------
Resolution: Fixed
My tests with the latest SVN show that getting metadata works - provided you explicitly disable fetching the thumbnail (which is corrupt in those images):
Map params = new HashMap();
params.put(Sanselan.PARAM_KEY_READ_THUMBNAILS, Boolean.FALSE);
IImageMetadata metadata = Sanselan.getMetadata(file, params);
Resolving fixed.

> I'm trying to load the metadata from image files generated by a JAI-PULNIX camera, model TS-1327EN.
> I am specifically interested in getting the following tag values:
> ExifTagConstants.EXIF_TAG_IMAGE_DESCRIPTION,
> ExifTagConstants.EXIF_TAG_DATE_TIME_ORIGINAL and
> ExifTagConstants.EXIF_TAG_SUB_SEC_TIME_ORIGINAL.
> But, when the following line of code is executed:
> IImageMetadata metadata = Sanselan.getMetadata(file);
> I get one of two errors:
> java.io.IOException: Invalid Segment: insufficient data

> If that is the case I could contact JAI-PULNIX and ask them to fix it, but I'm not sure what the problem is.
