colour.YcCbcCrc_to_RGB(YcCbcCrc: ArrayLike, in_bits: int = 10, in_legal: bool = True, in_int: bool = False, is_12_bits_system: bool = False, **kwargs: Any) numpy.ndarray[source]

Convert an array of Yc’Cbc’Crc’ colour encoding values to the corresponding RGB array of linear values.

  • YcCbcCrc (ArrayLike) – Input Yc’Cbc’Crc’ colour encoding array of linear float values.

  • in_bits (int) – Bit depth for integer input, or used in the calculation of the denominator for legal range float values, i.e. 8-bit means the float value for legal white is 235 / 255. Default is 10.

  • in_legal (bool) – Whether to treat the input values as legal range. Default is False.

  • in_int (bool) – Whether to treat the input values as in_bits integer code values. Default is False.

  • is_12_bits_system (bool) – Recommendation ITU-R BT.2020 EOTF (EOCF) adopts different parameters for 10 and 12 bit systems. Default is False.

  • in_range – Array overriding the computed range such as in_range = (Y_min, Y_max, C_min, C_max). If in_range is undefined, Y_min, Y_max, C_min and C_max will be computed using colour.models.rgb.ycbcr.ranges_YCbCr() definition.

  • kwargs (Any) –


RGB array of linear float values.

* This definition has input and output integer switches, thus the domain-range scale information is only given for the floating point mode.


This definition is specifically for usage with Recommendation ITU-R BT.2020 when adopting the constant luminance implementation.
