In trying to use the bias feature of the tiffcp tool, I discovered that the tiff images I was trying to modify were reported as having more than 1 sample/pixel, so I got an error result instead of the expected processing. I spent some time with the tiffinfo tool looking at various images because I really didn't know much about the specific format of the images in question. It reported that they were compressed using the "CCITT Group 4" method, which I thought was a monochrome format, so the message about more than 1 sample/pixel was a bit confusing. I thought maybe I didn't understand enough about the image properties. In fact, I almost posted a message to this list but decided I'd do some research first.

What version of libtiff are you using? Since you are new to libtiff, perhaps you are using an outdated version?
