Simple Question:  How do I place the IFD at the beginning of the file 
(after the header)?

I'm building a TIF with LIBTIFF, and it places the directory after the 
strip.  I'd like to place it in the front of the file (behind the header).
I'm basically doing this:
TIFOpen ()
TIFCreateDirectory ()
TIFSetField ()
TIFSetField ()
...
loop -   TIFWriteScanLine ()
TIFClose ()

Rearraning the TIFCreateDirectory didn't do it.

I know it doesn't matter, but we are trying to emulate a component from a 
major vendor, and want to demonstrate that the image files are virtually 
identical.  I don't want to get caught up in an explaination to some 
illiterate VP

Thanks for any help.
