I'm sure I'm not following this too well (been on holidays, my mind is too
relaxed :-)) Are you saying that you can't decode any TIFF image without
using internal structures? Or are you saying you want to use libtiff to
decode just the CCITT G3/G4 formats?
If you just want something that can do G3/G4 format, perhaps libtiff might not
be the right answer. KDE's okular viewer has code extracted from the viewfax
utility. See faxexpand.cpp and faxexpand.h in
http://websvn.kde.org/trunk/KDE/kdegraphics/okular/generators/fax/
(it isn't really C++ though).
[There is a serious problem with copying internal libtiff headers - they
aren't stable. If you want to copy the headers, you'll have to fork the
library and include the whole thing.]
