space_from_chromaticities

Description:

public unowned Object? space_from_chromaticities (string? name, double wx, double wy, double rx, double ry, double gx, double gy, double bx, double by, Object trc_red, Object? trc_green, Object? trc_blue, SpaceFlags flags)

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 space passing its name;

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

Parameters:

name	The name for the color space
wx	The X-coordinate of the color space's white point
wy	The Y-coordinate of the color space's white point
rx	The X-coordinate of the red primary
ry	The Y-coordinate of the red primary
gx	The X-coordinate of the green primary
gy	The Y-coordinate of the green primary
bx	The X-coordinate of the blue primary
by	The Y-coordinate of the blue primary
trc_red	The red component of the TRC.
trc_green	The green component of the TRC (can be null if it's the same as `trc_red`).
trc_blue	The blue component of the TRC (can be null if it's the same as `trc_red`).
flags	The SpaceFlags
