The -hls argument

[SnowsatMan]

I try to convert tga files with colors in tga files in grey levels but I need to keep the opacity of the picture.

I try to use like in XnView the saturation with the -hls argument of nconvert but when I do it :

Code: Select all

"C:\program files\xnview\nconvert" -npcd 2 -size 256x256+0 -ctype grey -corder inter -out tga -hls 0 0 -100 "D:\image.tga"

nconvert returns

Code: Select all

Bad argument -'hls'

What's wrong in my line ?
Thanks
