Trouble with Unknown TIFF IFD Tags

Open RvanVeenendaal opened this issue 1 year ago • 1 comments

Sometimes JHOVE reports TIFF-HUL-12 "Unknown TIFF IFD Tag" messages. The latest versions of JHOVE seem to have a problem showing the unknown tag's number. There are additional characters at the end of the reported tag number string. Compare the bold InfoMessages below, for JHOVE 1.28.0, 1.26.1 and 1.20.1. For reproduction, use the file from https://github.com/openpreserve/jhove/issues/657.

Issue(s):

  1. JHOVE should not report the additional characters at the end of the reported tag number string
  2. Why does JHOVE 1.28.0 report the tags in a different order than the older versions?

JHOVE output for 1.28.0, 1.26.1 and 1.20.1:
