-	addtiffo 1.0
-	============
-
-The addtiffo utility is used to add overview pyramids to an existing 
-TIFF or GeoTIFF file.  Some applications can take advantage of these
-overviews to accelerate overview display performance of large rasters. 
-
-This release of addtiffo is primarily intended for compatibility testing
-with applications, and to see if there is interest in a cleaner release
-of the capability ... perhaps incorporation into the libtiff tools 
-distribution. 
-
-Please feel free to contact me with questions, or problems.

-Usage
------
-
-Usage: addtiffo [-r {average/nearest} [-subifd] 
-                tiff_filename [resolution_reductions]
-
-Example:
- % addtiffo abc.tif 2 4 8 16
-
-The numeric arguments are the list of reduction factors to 
-generate.  In this example a 1/2, 1/4 1/8 and 1/16 
-
-
-
-Limitations
------------
-
-See tif_overview.cpp for up to date details. 
-
-  o Currently only images with bits_per_sample of a multiple of eight
-    will work.
-
-  o The code will attempt to use the same kind of compression,
-    photometric interpretation, and organization as the source image, but
-    it doesn't copy geotiff tags to the reduced resolution images.
-
-  o Reduced resolution overviews for multi-sample files will currently
-    always be generated as PLANARCONFIG_SEPARATE.  This could be fixed
-    reasonable easily if needed to improve compatibility with other
-    packages.  Many don't properly support PLANARCONFIG_SEPARATE. 
-
-  o Overviews are always written as appended IFDs, rather than using the
-    ``tree of tree's'' approach using the SUBIFD tag.  I wanted to implement
-    both, but it isn't currently easy to add a SUBIFD tag to an existing
-    main tiff IFD with libtiff.  I hope to try this again later.

-TIFF File Tags
---------------
-
-The results of running addtiffo on a 1024x1024 tiled greyscale file 
-with the arguments ``2 4 8 16'' is to add four additional TIFF directories
-appended on the file with the SUBFILETYPE flag to 0x1 indicating the extra
-items are reduced resolution images. 
-
-The tiffinfo output of such a file might look like this:
-
-TIFF Directory at offset 0x118008
-  Image Width: 1024 Image Length: 1024
-  Tile Width: 256 Tile Length: 112
-  Bits/Sample: 8
-  Compression Scheme: none
-  Photometric Interpretation: min-is-black
-  Samples/Pixel: 1
-  Planar Configuration: single image plane
-TIFF Directory at offset 0x15e1d2
-  Subfile Type: reduced-resolution image (1 = 0x1)
-  Image Width: 512 Image Length: 512
-  Tile Width: 256 Tile Length: 112
-  Bits/Sample: 8
-  Compression Scheme: none
-  Photometric Interpretation: min-is-black
-  Samples/Pixel: 1
-  Planar Configuration: separate image planes

-Building
---------
-
-You will need a C compiler.  You will need to have libtiff already
-built and installed.  The provided Makefile should work on most Unix systems.
-A similar file will be needed for Windows, but is not provided. 
-
-The CFLAGS and LIBS macros in the Makefile will have to be updated to 
-point to the correct location of the libtiff include files, and library.

-Credits
--------
-
- o Intergraph Corporation for partially funding the work. 
-
- o Global Geomatics for partially funding reorganization of the overview
-   building ability as a separate utility.
-
- o Orrin Long, and Ed Grissom of Intergraph for explaining what needed to 
-   be done. 
-
- o Max Martinez of Erdas for his discussion of external overviews. 
-
- o Atlantis Scientific who supported adding averaging, and some other
-   generalizations. 
-
- o Frank Warmerdam for writing the bulk of the code. 
-
- o Sam Leffler since this only exists because of his libtiff.
