[Gimp-developer] about gimp_rgb_to_hsl and gimp_colorize

[hejian <hejian he gmail com>]

I am trying to write a plugin, this is the code snippet:

    GimpHSL hsl;
    gimp_rgb_to_hsl (&rbvals.color, &hsl);
    gimp_colorize(drawable->drawable_id, hsl.h, hsl.s, hsl.l);

It will got this error:

Calling error for procedure 'gimp-colorize':
Procedure 'gimp-colorize' has been called with value '-1.000000' for
argument 'hue' (#2, type gdouble). This value is out of range.

any suggestion is appreciated.
