Hi, I'm not sure what point you're making here. Make the perceptual
colorspace non-linear enough, and the geometric assumptions break down.
That's the nature of things. (ie. the -N5.5 failed in your particular case.
It won't necessarily fail there in other cases :- it could fail at lower
or higher values. I have no way of predicting this. If you have some way
of predicting this, then you should be writing scholarly articles on
non-Euclidean geometry :-)
Graeme Gill.
I will try make this clear
Targen documentation
-N emphasis Degree of neutral axis patch concentration 0-1. (default
0.50)
So after typing targen -N 1.5 I expected "Neautral weighting argument %f
to '-N' is out of range"
but targen accpets -N 1.5,it was sopposed to give me an error and i
havent got any errors.
so i looked into targen.c and ...

}
I do not understad why you're conditioning "perc_wght" but related
mesaage errors are to argumet Neutral weighting.
