Description

Old-style JPEG compression field. TechNote2 invalidates this part of the specification.

No new TIFF writer code should ever attempt to use this tag. It is part of an invalidated compression scheme, old-style JPEG, that was always unclear to begin with, and next enjoyed many mutualy exclusive implementations. The following description is for TIFF reading purposes only.

This field was originally intended to indicate the length of the JPEG stream pointed to by JPEGInterchangeFormat tag.
