Implementations

impl MasteringDisplay

pub const fn new( display_primaries: [(u32, u32); 3], white_point: (u32, u32), max_luminance: (u32, u32), min_luminance: (u32, u32), ) -> Self

Constructs a MasteringDisplay.

pub const fn display_primaries(&self) -> [(u32, u32); 3]

Display primary chromaticities (x, y) for R, G, B in CIE 1931, each coordinate normalized to SMPTE ST 2086 fixed-point units — 0.00002 increments, so a floating value is raw / 50000.0. The same units mediaframe::color::ChromaCoord uses, so a (x, y) pair here constructs one directly.

A tuple has room for one denominator, not two, so it cannot hold x and y each as an independent AVRational the way the source AVMasteringDisplayMetadata does — parse_mastering_ display (mediadecode-ffmpeg’s convert module) is the one place that resolves each coordinate’s own rational to this shared fixed-point unit, exactly rather than by rounding, for every producer this crate has observed (which all emit a denominator of 50000 already).

pub const fn white_point(&self) -> (u32, u32)

White-point chromaticity (x, y), in the same SMPTE ST 2086 fixed-point units as Self::display_primaries.

pub const fn max_luminance(&self) -> (u32, u32)

Maximum luminance in 0.0001 cd/m² units (rational (num, den)).

pub const fn min_luminance(&self) -> (u32, u32)

Minimum luminance in 0.0001 cd/m² units.

pub const fn with_display_primaries(self, value: [(u32, u32); 3]) -> Self

Sets the display primaries (consuming builder).

pub const fn with_white_point(self, value: (u32, u32)) -> Self

Sets the white point (consuming builder).

pub const fn with_max_luminance(self, value: (u32, u32)) -> Self

Sets the max luminance (consuming builder).

pub const fn with_min_luminance(self, value: (u32, u32)) -> Self

Sets the min luminance (consuming builder).

pub const fn set_display_primaries( &mut self, value: [(u32, u32); 3], ) -> &mut Self

Sets the display primaries in place.

pub const fn set_white_point(&mut self, value: (u32, u32)) -> &mut Self

Sets the white point in place.

pub const fn set_max_luminance(&mut self, value: (u32, u32)) -> &mut Self

Sets the max luminance in place.

pub const fn set_min_luminance(&mut self, value: (u32, u32)) -> &mut Self

Sets the min luminance in place.
