    I using TIFF v1.36 on a DOS machine.  I got the code for John Levine's book
    "Programming for Graphics files in C and C++.

I'm not sure how the code that you got from this book relates to the
software that I give away.  There is no v1.36 of my software.
    When I attempt to do a TIFFWriteScanline it displays the error message
    must set Planar Configuration, and I have already set the planar configuration
    to PLANAR_CONTIG using TIFFSetField.  I do not understand why I am getting this
    error.  I commented out the error checker in the library routine and recompiled
    and I am able to store a grey scale tiff file but some program are unable to
    read it.   I was wondering if there is a bug in the library or if I am doing
    something wrong.

Hard to say since I don't know what code you've got (though it certainly
sounds a lot of my library).
    Also the documentation I have is unclear on how I should set the strip
    offsets tag.  It says it is required but I understand how to set it.
    (typo above)  The manual says the tag must be set but I do not understand 
    what I am supposed to set it to.
In the software I give away you do not set the strip offsets tag directly.
It is automatically written for you as a consequence of writing out image
