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?
Thanks, Matt Klaric
