[gdal-dev] offset and scale

[Trent M Hare]

I have a set of existing 16bit geoTiffs.  While converting there was no 
"Offset" or "Scale" in the converted image. I now need to add a Offset and 
Scale values postmortem such that at least the label is correct.  Is there 
a clever way to do this on the existing images or even maybe via a created 
VRT format and a convert again?

thanks,
Trent
