Function bgr_to_xyz

pub fn bgr_to_xyz(
    src: &[u8],
    src_stride: u32,
    dst: &mut [f32],
    dst_stride: u32,
    width: u32,
    height: u32,
    matrix: &[[f32; 3]; 3],
    transfer_function: TransferFunction,
)

This function converts BGR to XYZ. 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 XYZ data
• dst_stride - Bytes per row for dst data
• matrix - Transformation matrix from BGR to XYZ. If you don’t have specific just pick SRGB_TO_XYZ_D65
• transfer_function - Transfer function from gamma to linear space. If you don’t have specific pick Srgb
