    pub gain_map_min_n: i32,
    pub gain_map_min_d: u32,
    pub gain_map_max_n: i32,
    pub gain_map_max_d: u32,

}

Per-channel gain map parameters from ISO 21496-1.

Each field is a rational number (numerator/denominator pair) describing how to apply the gain map for this channel.

Fields

gain_map_min_n: i32

Minimum gain map value (numerator).

gain_map_min_d: u32

Minimum gain map value (denominator).

gain_map_max_n: i32

Maximum gain map value (numerator).

gain_map_max_d: u32

Maximum gain map value (denominator).

gamma_n: u32

Gamma curve parameter (numerator).

gamma_d: u32

Gamma curve parameter (denominator).

base_offset_n: i32

Base image offset (numerator).

base_offset_d: u32

Base image offset (denominator).

alternate_offset_n: i32

Alternate image offset (numerator).

alternate_offset_d: u32

Alternate image offset (denominator).

Trait Implementations

impl Clone for GainMapChannel

fn clone(&self) -> GainMapChannel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GainMapChannel

impl Debug for GainMapChannel

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

Formats the value using the given formatter.

impl Eq for GainMapChannel

impl From<&GainMapChannel> for GainMapChannel

fn from(ch: &GainMapChannel) -> Self

Converts to this type from the input type.

impl From<&GainMapChannel> for GainMapChannel

fn from(ch: &GainMapChannel) -> Self

Converts to this type from the input type.

impl PartialEq for GainMapChannel

fn eq(&self, other: &GainMapChannel) -> 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.
