plug-ins/libgck/gck/gck.h removed the GckRGB color type and all it's 2001-01-01 Michael Natterer <mitch@gimp.org> * plug-ins/libgck/gck/gck.h * plug-ins/libgck/gck/gckcolor.c: removed the GckRGB color type and all it's functions. * libgimp/Makefile.am * libgimp/gimpcolor.[ch]: new files containing the new GimpRGB color type and assorted functions. * libgimp/gimpcolorspace.[ch]: colorspace conversion routines for the new GimpRGB type. Also taken from LibGCK. * libgimp/gimp.h * libgimp/gimptypes.h: #include "gimpcolor.h". It's ugly to include it in both files but unavoidable to follow our new "*.c" file include policy. This will go away as libgimp will be chopped up into pieces anyway. * app/apptypes.h * app/asupsample.[ch] * app/blend.c * app/color_transfer.h * app/gradient_header.h: removed "color_t" and use GimpRGB instead. * plug-ins/Lighting/lighting_apply.c * plug-ins/Lighting/lighting_image.c * plug-ins/Lighting/lighting_image.h * plug-ins/Lighting/lighting_main.c * plug-ins/Lighting/lighting_main.h * plug-ins/Lighting/lighting_preview.c * plug-ins/Lighting/lighting_shade.c * plug-ins/Lighting/lighting_shade.h * plug-ins/MapObject/mapobject_apply.c * plug-ins/MapObject/mapobject_image.c * plug-ins/MapObject/mapobject_image.h * plug-ins/MapObject/mapobject_main.c * plug-ins/MapObject/mapobject_main.h * plug-ins/MapObject/mapobject_preview.c * plug-ins/MapObject/mapobject_shade.c * plug-ins/MapObject/mapobject_shade.h * modules/colorsel_triangle.c: s/GckRGB/GimpRGB/g * plug-ins/gdyntext/gdyntextcompat.h: check also for GIMP's minor version when deciding if to add a missing PDB wrapper. (All this compat cruft including libgimp/gimpcompat.h should go away ASAP)

* gimp_rgb_to_cmyk:
* @rgb: A value in the RGB colorspace
* @pullout: A scaling value (0-1) indicating how much black should be
* pulled out
* @cmyk: The input value naively converted to the CMYK colorspace
*
* 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.
