Struct DisplayGamma 

pub struct DisplayGamma(/* private fields */);

Display gamma, decoded from EDID base block byte 0x17.

Gamma is encoded as (value * 100) - 100, so a stored byte of 120 represents gamma 2.20. A byte value of 0xFF means gamma is undefined; use None on DisplayCapabilities in that case.

Implementations

impl DisplayGamma

pub fn from_edid_byte(byte: u8) -> Option<DisplayGamma>

Decodes EDID byte 0x17 into a DisplayGamma.

Returns None if the byte is 0xFF (gamma not specified).

pub fn raw(&self) -> u8

Returns the raw encoded byte.

pub fn value(&self) -> f32

Returns the gamma value as a floating-point number (e.g. 2.20).
