Struct ChromaLayout 

pub struct ChromaLayout {
    pub shift_x: u32,
    pub shift_y: u32,
    pub uv_rows_per_luma: usize,
}

Chroma addressing parameters for a semi-planar (NV12/NV16/NV24) format — the single source of truth shared by the codec writer, CPU readers, and the Linux + macOS GL shaders. See PixelFormat::chroma_layout.

Fields

shift_x: u32

Right-shift applied to the luma x to get the chroma column: 1 = half horizontal resolution (NV12/NV16), 0 = full resolution (NV24).

shift_y: u32

Right-shift applied to the luma y to get the chroma row: 1 = half vertical resolution (NV12), 0 = full vertical resolution (NV16/NV24).

uv_rows_per_luma: usize

Physical buffer rows the UV plane advances per chroma line: 1 for NV12/NV16 (one (Cb,Cr) line fits in a single stride-wide row), 2 for NV24 (a full-width 2*W-byte chroma line spans two stride-wide rows).

Trait Implementations

impl Clone for ChromaLayout

fn clone(&self) -> ChromaLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChromaLayout

impl Debug for ChromaLayout

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

Formats the value using the given formatter.

impl Eq for ChromaLayout

impl PartialEq for ChromaLayout

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