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