Controlling Hue Chroma ?

[Alpha504]

Hi,

I would like to modify the hue-chroma of some images.

I tried the following function:

Code:

(gimp-drawable-hue-chroma drawable MODE-REPLACE -60 20 0 100.0)

But it gives me an error:

Code:

Error: eval: unbound variable: gimp-drawable-hue-chroma

If someone knows which command to use and what are the parameters ?
