Introduction Since 1992 Kofax has supported the use of a TIFF file with JPEG compression (TIFF-JPEG) for the storage of multi-bit images (color or grayscale). Kofax implemented the TIFF-JPEG storage filter in accordance with a simplified and widely accepted interpretation of the TIFF 6.0 specification for handling JPEG compression within a TIFF file. As a standard, TIFF-JPEG was non-specific and confusing, leaving developers open to interpreting the specification.
Following the TIFF 6.0 specification, there was a Draft TIFF Technical Note #2. This draft attempted to clarify the support for TIFF-JPEG; however, the draft was never brought to be accepted as a standard.
Additionally, the Technical Note #2 implementation was incompatible with the existing format outlined in the TIFF 6.0 specification. Developers of storage and display technologies that wish to leverage the benefits of a TIFF file with JPEG compression now have to make an implementation decision based upon the format and interpretation they believe will be most utilized by their customer base. Unfortunately the varied formats may not work together.
Recently with advancements in scanning technologies, imaging software, and algorithms we are seeing more customers turn to the use of multi-bit images within their document management/imaging workflows. Whereas the TIFF standard for binary images is well documented and accepted by imaging developers (i.e. binary images written as TIFF files have an extremely high probability of being displayed and read by a wide variety of engines), TIFF-JPEG images written by one vendor according to their interpretation of the TIFF-JPEG specification may not be read by another vendor because of a differing interpretation/implementation of the specification. The problem this creates is one in which images scanned with one vendors implementation of TIFF-JPEG may not be able to be displayed and leveraged by another vendors repository or management system.
