Function bgr_to_oklab

pub fn bgr_to_oklab(
    src: &[u8],
    src_stride: u32,
    dst: &mut [f32],
    dst_stride: u32,
    width: u32,
    height: u32,
    transfer_function: TransferFunction,
)

This function converts BGR to Oklab against D65 white point. This is much more effective than naive direct transformation

Arguments

• src - A slice contains BGR data
• src_stride - Bytes per row for src data.
• width - Image width
• height - Image height
• dst - A mutable slice to receive LAB(a) data
• dst_stride - Bytes per row for dst data
• transfer_function - transfer function to linear colorspace
