This is pretty much what I thought, but it does beg one question - why does Microsoft's viewer obey the Photometric flag in the original, but not the tiffcp created tiff?

Larry,

I think the G3 and G4 compression formats have an implicit assumption about what is white and what is black. This may have led Microsoft to ignore the photometric tags.

Also, this is less related to libtiff, but does anyone have any pointers on how I might cross-compile libtiff+tools for windows under linux?

Folks have done it, but I don't know the details. You might want to look around the MingW project. I think they may provide cross compilers.

Best regards,
