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. > > -- This message was sent by Atlassian Jira (v8.20.10#820010)
