Hi,<br><br>I ran gdalwarp in order to remap the 0,0,0 pixels to 0,0,1 by using gdalwarp.exe -srcnodata 0 0 0 -dstnodata 0 0 1. After running gdalwarp -mm it still has the min as being 0.000 even though I know that the pixels were changed by gdalwarp but why does dgalinfo still have the min value as
0.000 for all 3 colors? Gdalinfo dump below:<br><br>Driver: GTiff/GeoTIFF<br>Size is 5446, 4648<br>Coordinate System is:<br>GEOGCS["WGS 84",<br> DATUM["WGS_1984",<br> SPHEROID["WGS 84",6378137,
