Hi all,
I'm new to image processing, so I'm sorry if this is a dumb question.
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

I'm attaching two files. One for each of the errors.
Is there something wrong with the encoding of these images?
If that is the case I could contact JAI-PULNIX and ask them to fix, but I'm not
sure
what the problem is.
Any help would be much appreciated.
Thank you,
Bruno Abreu
