Importing compressed TIFF files

[Louis Clarke]

Hello,

I wish to import a standard TIFF 6.0 8-bit color pallette packbit compressed 
file into GRASS.  I pulled the r.in.tiff_sun file off the moon and attempted 
to pull this into GRASS.  The r.in.tiff_sun did not work with this file, it 
errored out.

Does anyone know how to read this type of compressed file directly into GRASS 
or through an intermediate program?  There is also a TIFF World File which 
contains the affine transformation coordinates needed to allow ERDAS, 
ArcInfo, and ArcView to treat the .tif file as a geo-referenced raster image.  
I wish to create a cellhd file that will give the imported TIFF image 
geo-references.

Any help would be appreciated.  Thanks.
