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

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.
Parameters
- name
- 
            Type: const char*The name for the color space. The argument can be NULL.The data is owned by the caller of the function. The value is a NUL terminated UTF-8 string. 
- wx
- 
            Type: doubleThe X-coordinate of the color space’s white point. 
- wy
- 
            Type: doubleThe Y-coordinate of the color space’s white point. 
- rx
- 
            Type: doubleThe X-coordinate of the red primary. 
- ry
- 
            Type: doubleThe Y-coordinate of the red primary. 
- gx
- 
            Type: doubleThe X-coordinate of the green primary. 
- gy
- 
            Type: doubleThe Y-coordinate of the green primary. 
- bx
- 
            Type: doubleThe X-coordinate of the blue primary. 
- by
- 
            Type: doubleThe Y-coordinate of the blue primary. 
- trc_red
- 
            Type: BablThe red component of the TRC. The data is owned by the caller of the function. 
- trc_green
- 
            Type: BablThe green component of the TRC (can be NULLif it’s the same astrc_red).The argument can be NULL.The data is owned by the caller of the function. 
- trc_blue
- 
            Type: BablThe blue component of the TRC (can be NULLif it’s the same astrc_red).The argument can be NULL.The data is owned by the caller of the function. 
- flags
- 
            Type: BablSpaceFlagsThe BablSpaceFlags.
