xyY_to_xy
(xyY)[source]¶ Converts from CIE xyY colourspace to xy chromaticity coordinates.
xyY
argument with last dimension being equal to 2 will be assumed to be a xy chromaticity coordinates argument and will be returned directly by the definition.Parameters: xyY (array_like) – CIE xyY colourspace array or xy chromaticity coordinates. Returns: xy chromaticity coordinates. Return type: ndarray Notes
- Input CIE xyY colourspace array is in domain [0, 1].
- Output xy chromaticity coordinates are in range [0, 1].
