Class (GI Struct)

Gsk-4.0 ▶ Gsk ▶ ComponentTransfer`Since 4.20`

Specifies a transfer function for a color component to be applied while rendering.

The available functions include linear, piecewise-linear, gamma and step functions.

Note that the transfer function is applied to un-premultiplied values, and all results are clamped to the [0, 1] range.
