pub fn create_hanning_window(
    dst: &mut impl ToOutputArray,
    win_size: Size,
    typ: i32
) -> Result<()>

   Mat hann;
   createHanningWindow(hann, Size(100, 100), CV_32F);

Parameters

• dst: Destination array to place Hann coefficients in
• winSize: The window size specifications (both width and height must be > 1)
• type: Created array type
