svn commit: r995554 - in /commons/proper/sanselan/trunk/src: main/java/org/apache/sanselan/formats/tiff/fieldtypes/ test/java/org/apache/sanselan/formats/jpeg/exif/

Author: cmchen
Date: Thu Sep  9 19:32:21 2010
New Revision: 995554

URL: http://svn.apache.org/viewvc?rev=995554&view=rev
Log:
Fix for bug introduced by last patch.
ASCII TIFF/Exif values were not correctly padded with a trailing zero.
Also suppressed an image with invalid EXIF data that was breaking the ExifRewriteText.
