Does anyone have any experience using 1-bit TIFF images with GDAL?  The
GeoTIFF file format page (http://www.gdal.org/frmt_gtiff.html) indicates
that they can be read, but is silent on the issue of writing them.  I'm
interested in writing them using GDAL, but it appears that the 1-bit data
type is not valid in GDAL(
http://gdal.org/gdal_8h.html#22e22ce0a55036a96f652765793fb7a4).  Does anyone
have any experience with this?  How difficult would it be to modify the TIFF
driver to handle these?
