    thanks to tifflib, and CxImage class, ImageMagick for inspiration. Please send any modifications to 
    +s i r r u b e 2 @ y a h o o . c o m+ so I can implement them as well if I choose. 

    Thanks to all the coders on code project in the past who have shared thier source as well.

    To build you need CXImage and libtiff.  /cvsroot/osrs/libtiff/libtiff.
