Hi All,

I am getting an error using i.colors.enhance on Windoes Grass 7.2.1 which crashes the session.

I get the following error in the command window.

Any advice would be greatly appreciated.

Cheers
Andrew

tested here with

System Info
GRASS version: 7.2.1
GRASS SVN revision: r71013
Build date: 2017-05-03

and the example from the manual:

https://grass.osgeo.org/grass73/manuals/i.colors.enhance.html

------
g.region raster=lsat7_2002_10 -p
i.colors.enhance blue=lsat7_2002_10 green=lsat7_2002_20 red=lsat7_2002_30
strength=95
------
it works as expected.

did you set your region to your images? could you test the manual example
with the NC sample data set?

-----
best regards
Helmut
