[jira] Created: (SANSELAN-35) IPTCParser fails after encountering
record number 1
IPTCParser fails after encountering record number 1
---------------------------------------------------
Key: SANSELAN-35
URL: https://issues.apache.org/jira/browse/SANSELAN-35
Project: Commons Sanselan
Issue Type: Bug
Reporter: Alex Vigdor
Priority: Minor
IPTCParser fails to find valid metadata in a JPEG after it encounters a record number 1 (it only extracts metadata from records numbered 2). A little debugging showed that this is because it was not properly moving the buffer pointer to the end of the record to pick up subsequent valid records - moving the record number check after the pointer update fixes the problem. I will attach a patch and sample image.

[jira] Updated: (SANSELAN-35) IPTCParser fails after encountering
record number 1
Posted by "Alex Vigdor (JIRA)" <ji...@apache.org>.

Alex Vigdor updated SANSELAN-35:
--------------------------------
Attachment: SANSELAN-35.patch

The JPG file demonstrates the bug - use ImageMagick, Photoshop or an other tool and see valid IPTC metadata, but Sanselan misses it. After applying the attached patch, Sanselan does find the metadata in the JPG.
