Function vizia::vg::yuva_info::plane_subsampling_factors

pub fn plane_subsampling_factors(
    plane: SkYUVAInfo_PlaneConfig,
    subsampling: Subsampling,
    plane_index: usize,
) -> (i32, i32)

SubsamplingFactors(Subsampling) if plane_index refers to a U/V plane and otherwise (1, 1) if inputs are valid. Invalid inputs consist of incompatible PlaneConfig Subsampling plane_index combinations. (0, 0) is returned for invalid inputs.
