colour.models.cctf_decoding_ProPhotoRGB¶
- colour.models.cctf_decoding_ProPhotoRGB(X_p, bit_depth=8, in_int=False)¶
Define the ProPhoto RGB decoding colour component transfer function (Encoding CCTF).
- Parameters
X_p – Non-linear data \(X'_{ROMM}\).
bit_depth – Bit depth used for conversion.
in_int – Whether to treat the input value as integer code value or float equivalent of a code value at a given bit depth.
- Returns
Linear data \(X_{ROMM}\).
- Return type
