babl_space_from_chromaticities (
  const char* name,
  double wx,
  double wy,
  double rx,
  double ry,
  double gx,
  double gy,
  double bx,
  double by,

)

Description [src]

Creates a new babl-space/ RGB matrix color space definition with the specified CIE xy(Y) values for white point: wx, wy and primary chromaticities: rx,ry,gx,gy,bx,by and TRCs to be used. After registering a new babl-space it can be used with babl_space() passing its name;

Internally this does the math to derive the RGBXYZ matrix as used in an ICC profile.
