colour.models.oetf_RIMMRGB(X, I_max=255, E_clip=2.0)

Defines the RIMM RGB encoding opto-electronic transfer function (OETF / OECF).

RIMM RGB encoding non-linearity is based on that specified by Recommendation ITU-R BT.709-6.

Parameters:

• X (numeric or array_like) – Linear data \(X_{RIMM}\).
• I_max (numeric, optional) – Maximum code value: 255, 4095 and 650535 for respectively 8-bit, 12-bit and 16-bit per channel.
• E_clip (numeric, optional) – Maximum exposure level.

Returns:

Non-linear data \(X'_{RIMM}\).

Return type:

numeric or ndarray
