Enum libcamera::controls::AeMeteringMode

#[repr(i32)]
pub enum AeMeteringMode {
    MeteringCentreWeighted = 0,
    MeteringSpot = 1,
    MeteringMatrix = 2,
    MeteringCustom = 3,
}

Specify a metering mode for the AE algorithm to use. The metering modes determine which parts of the image are used to determine the scene brightness. Metering modes may be platform specific and not all metering modes may be supported.

Variants

MeteringCentreWeighted = 0

Centre-weighted metering mode.

MeteringSpot = 1

Spot metering mode.

MeteringMatrix = 2

Matrix metering mode.

MeteringCustom = 3

Custom metering mode.

Trait Implementations

impl Clone for AeMeteringMode

fn clone(&self) -> AeMeteringMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ControlEntry for AeMeteringMode

const ID: u32 = 3u32

impl Debug for AeMeteringMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<AeMeteringMode> for ControlValue

fn from(val: AeMeteringMode) -> Self

Converts to this type from the input type.

impl From<AeMeteringMode> for i32

fn from(enum_value: AeMeteringMode) -> Self

Converts to this type from the input type.

impl PartialEq for AeMeteringMode

fn eq(&self, other: &AeMeteringMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<ControlValue> for AeMeteringMode

type Error = ControlValueError

The type returned in the event of a conversion error.

fn try_from(value: ControlValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<i32> for AeMeteringMode

type Error = TryFromPrimitiveError<AeMeteringMode>

The type returned in the event of a conversion error.

fn try_from(number: i32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for AeMeteringMode

type Primitive = i32

const NAME: &'static str = "AeMeteringMode"

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>
