implementation of geotiff keys [message #65080]

Hello,
In order to be able to write large geotiff (i.e. without using
WRITE_TIFF which has to load the data), I have recycled the "obsolete"
procedure TIFF_WRITE.pro (still distributed with IDL). Presently I can
write large tiff files of float data whitout having to load the whole
dataset in memory.
Now I would like to write some geotiff tags and keys to my tiff file,
but I cannot figure out clearly how to proceed. Has anyone an example
of code showing how to pass parameters and manage the offsets when
writing the geotiff keys/tags?

Thank you
Marc
