> TIFF tags 0x111 and 0x117 have wrong descriptive names
> ------------------------------------------------------
>
> Key: IMAGING-362
> URL: https://issues.apache.org/jira/browse/IMAGING-362
> Project: Commons Imaging
> Issue Type: Bug
> Components: Format: TIFF
> Affects Versions: 1.0-alpha2
> Reporter: Gary Lucas
> Priority: Minor
> Fix For: 1.0
>
>
> The TIFF standard defines metadata elements using integer code values. For
> code values 0x111 and 0x117, Commons Imaging associates these with incorrect
> names "PreviewImageStart" and "PreviewImageLength". According to the
> specification "TIFF Revision 6.0 Final – June 3, 1992", the correct names for
> these are "StripOffsets" and "StripByteCounts". In fact, the word "preview"
> never even shows up in the TIFF specification.
> This should be an easy fix. No new test cases will be required, since these
> are descriptive elements only.
> The role of these two elements is to define the file position and length of
> data elements for TIFF files that are encoded as strips.
> One of the example programs in the Commons Imaging distribution (which is not
> compiled) is called ReadTagsAndImages.java. It can be used to dump TIFF tags.
