Function lab_with_alpha_to_bgra

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

This function converts LAB with separate alpha channel to BGRA. This is much more effective than naive direct transformation

Arguments

• src - A slice contains LAB data
• src_stride - Bytes per row for src data.
• dst - A mutable slice to receive BGRA data
• dst_stride - Bytes per row for dst data
• width - Image width
• height - Image height
• matrix - Transformation matrix from RGB to XYZ. If you don’t have specific just pick XYZ_TO_SRGB_D65
• transfer_function - Transfer function. If you don’t have specific pick Srgb
