[gdal-dev] translating palettes in geotiff

[David Strip]

I have a paletted geotiff that I want to modify by mapping palette 
entries to a new palette.
Thus, I have an input palette, an output palette, and a geotiff.  I have 
a mapping (many to 1, if it matters) from the input palette to the 
output palette. Each pixel in the output geotiff will have a value 
equivalent to mapping the input geotiff's pixel value through the map.

I've looked over the utilities and none seems to have this capability. 
It would be pretty easy, I think to write code using gdal to do this, 
but if one of the utilities will handle this case, that's even better.

Thanks.
