Implementations
impl ChromaSampling
impl ChromaSampling
pub fn get_decimation(self) -> Option<(usize, usize)>
pub 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.
