[FWTools] Extract to binary with meta, manipulate, then project

[Simon Hook]

Hi,

If I have an ASTER image, can I extract the bands as flat binary, 
including the geocoding info. Manipulate the flat binary with my code 
and then pass the manipulated binary (same size as original) with 
geocoding info to gdal and have it generate a geotif or jpg with world file?

Thanks, Simon
