gimp_rgb_to_cmyk (
const GimpRGB* rgb,

GimpCMYK* cmyk
)
Description [src]
Does a naive conversion from RGB to CMYK colorspace. A simple
formula that doesn’t take any color-profiles into account is used.
The amount of black pullout how can be controlled via the pullout
parameter. A pullout
value of 0 makes this a conversion to CMY.
A value of 1 causes the maximum amount of black to be pulled out.
