void
gimp_rgb_to_cmyk (
  const GimpRGB* rgb,
  gdouble pullout,
  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.

Parameters

A scaling value (0-1) indicating how much black should be pulled out.

cmyk GimpCMYK
 

The input value naively converted to the CMYK colorspace.
