[Gdal-dev] gdalwarp color management

[Simone]

Much probably your image is internally compressed
and doing a simple warp on it is decompressing it.

I guess if you copy and paste here a gdalinfo on the original image as well 
the gdalwarp comman line you used we could be of more help.


Ciao,
Simone.
