Enum TransferFunction 

pub enum TransferFunction {
    Srgb,
    Linear,
    Bt709,
}

How a buffer’s stored values relate to light intensity.

Independent of YuvRange (where structural black and white sit in the integers) and of the layout dimensions SurfaceFormatKind carries: the same bytes can be sRGB-encoded or linear, and the range is a separate axis again.

The default for an RGB buffer is Srgb — desktop buffers, screen capture and UI assets are sRGB-encoded — and for a YCbCr one Bt709, whose matrix already produces non-linear R'G'B'. Linear is what a 3D engine’s linear render target carries; the renderer encodes it before compositing.

Variants

Srgb

sRGB-encoded (IEC 61966-2-1): the default for 8-bit RGB.

Linear

Linear light: what an engine’s render target holds before any display encoding.

Bt709

The BT.709 curve (BT.601 shares it): YCbCr video’s non-linear R'G'B'.
