lab2xyz(lab, illuminant='D65', observer='2')
By default Observer= 2A, Illuminant= D65. CIE XYZ tristimulus values x_ref = 95.047, y_ref = 100., z_ref = 108.883. See function 'get_xyz_coords' for a list of supported illuminants.
The image in Lab format. Final dimension denotes channels.
The name of the illuminant (the function is NOT case sensitive).
The aperture angle of the observer.
If lab
is not at least 2-D with shape (..., 3).
If either the illuminant or the observer angle are not supported or unknown.
If any of the pixels are invalid (Z < 0).
The image in XYZ format. Same dimensions as input.
CIE-LAB to XYZcolor space conversion.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
