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.

self

A value in the RGB colorspace

pullout
