Enum `ChromaSampling`

#[repr(C)]
pub enum ChromaSampling

Chroma subsampling format

Variants

Cs420: Both vertically and horizontally subsampled.
Cs422: Horizontally subsampled.
Cs444: Not subsampled.
Cs400: Monochrome.

Implementations

`impl ChromaSampling`

const fn get_decimation(self) -> Option<(usize, usize)>: Provides the amount to right shift the luma plane dimensions to get the chroma plane dimensions. Only values 0 or 1 are ever returned. The plane dimensions must also be rounded up to accommodate odd luma plane sizes. Cs400 returns None, as there are no chroma planes.
const fn get_chroma_dimensions(self, luma_width: usize, luma_height: usize) -> (usize, usize): Calculates the size of a chroma plane for this sampling type, given the luma plane dimensions.
