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.] Brad
