Nice.

Saving and loading TIFF files is implemented as a plug-in. You can't
easily copy code from the core application (as found in the app
directory) to a plug-in. You can only use the API that is exported to
plug-ins. But you should find everything you need there. Check the API
reference and look for gimp_channel_get_color() and
gimp_channel_get_opacity().

Please base your efforts on the development branch or a recent 2.3
snapshot.
