title: "TransferParameters"
description: "Defines the parameters for the ICC parametric curve type 4, as defined in ICC.1:2004-10, section
10.15.

[The EOTF is of the form linked
here](https://d.android.com/reference/android/graphics/ColorSpace.Rgb.TransferParameters)

The corresponding OETF is simply the inverse function.

The parameters defined by this class form a valid transfer function only if all the following
conditions are met:
* No parameter is a [Not-a-Number][Double.isNaN]
* `d` is in the range `[0..1]`
* The function is not constant
* The function is positive and increasing"
