pub fn idct(
    src: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray, 
    flags: i32
) -> Result<()>

idct(src, dst, flags) is equivalent to dct(src, dst, flags | DCT_INVERSE).

Parameters

• src: input floating-point single-channel array.
• dst: output array of the same size and type as src.
• flags: operation flags.
