[gdal-dev] gdalenhance -config file how you do linear interpolation of the colors?

[Chaitanya kumar CH]

Nikolaos,

The gdalenhance utility is not really recommended. I don't know the config
file format.

GDAL's VRT driver[1] supports a look-up-table that works with linear
interpolation. In it, you specify pairs of corresponding values in source
and destination rasters. The intermediate source values are interpolated
linearly.
