TransferParameters
open class TransferParameters
| kotlin.Any | |
| ↳ | android.graphics.ColorSpace.Rgb.TransferParameters |
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:
\(\begin{equation} Y = \begin{cases}c X + f & X \lt d \\\ \left( a X + b \right) ^{g} + e & X \ge d \end{cases} \end{equation}\)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 - \(d\) is in the range \([0..1]\)
- The function is not constant
- The function is positive and increasing

Defines the parameters for the ICC parametric curve type 3, as defined in ICC.1:2004-10, section 10.15.
The EOTF is of the form:
\(\begin{equation} Y = \begin{cases}c X & X \lt d \\\ \left( a X + b \right) ^{g} & X \ge d \end{cases} \end{equation}\)This constructor is equivalent to setting \(e\) and \(f\) to 0.
