/*
*
* The TIFF specification was originally released in
* 1986 by Aldus Corporation as a standard method of storing
* black-and-white images created by scanners and desktop publishing
* applications. This first public release of TIFF was
* the third major revision of the TIFF format, and
* although it was not assigned a specific version number, this release
* may be thought of as TIFF Revision 3.0. The first
* widely used revision of TIFF, 4.0, was released in
* April 1987. TIFF 4.0 added support for uncompressed
* RGB color images and was quickly followed by the
* release of TIFF Revision 5.0 in August
* 1988. TIFF 5.0 was the first revision to add the
* capability of storing palette color images and support for the
* LZW compression algorithm. TIFF 6.0 was released in June
* 1992 and added support for CMYK and YCbCr color
*
