Nconvert, Ubuntu, HLS + GammaSat + AutoLevels + AutoContrast

[durumdara]

Hi!

I tried to move my photo tools to Ubuntu 9.10.

I installed xnview for linux on the machine. Today I tried to use my python script that calling nconvert with many modes.

But these modes failed to start:

• HLS
  GammaSat
  AutoLevels
  AutoContrast

I check the help - I have nconvert 4.51 - and it is show these commands in the help.

But when I try to use them I got error - unrecognized command...

Is this real, I need Windows to use these functions?

Thanks for your help:

Please update the nconvert version
