//
// File: TIFTemplate.bt
// Author: Kevin O. Grover <kevin@kevingrover.net>
// Purpose: A template for parsing TIFF (Tagged Image File Format) files.
// Version: $Revision: 61 $
// History:
// 2005-05-09 KOG Initial version
// 2005-05-11 KOG *Many* more TIFF Tag IDs (generated with a Perl script)
// 2005-05-19 KOG Added new iFax tags and best guess for MS Fax Tags
// 2005-06-30 KOG Updated MSFax Tag list
// 2007-02-28 KOG Updated for 010 2.1 (uses EnumToString)
// 2012-09 ELB add interpretation for GeoTiff (rev 1.8.2)
//
// This template was written to the TIFF6 specification. You can get the TIFF
// documentation from Adobe (http://www.adobe.com) after registering, or
// from the libtiff home page (http://www.libtiff.org).
//
// GeoTiff template written to GeoTIFF specification 1.8.2, which can be found at the following address:
// http://www.remotesensing.org/geotiff/spec/geotiffhome.html
//
// NOTE: This is NOT a comprehensive list of TIFF tags. Many are tags
// registered as private and not reported anywhere. If you run
// across any definitions, forward them to me and I'll add them
// to this template.
//--------------------------------------
// TODO
// - ADD: ??Color highlighting?? (ENT=gray, DATA=??, EXTERNAL DATA=??)
// - Types to Test: eBYTE, eSBYTE, eSSHORT, eSLONG, eFLOAT, eDOUBLE
// Check the Byte Order Mark to determine if file is Little or Big Endian
