Function opencv::core::copy_to

pub fn copy_to(
    src: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray, 
    mask: &dyn ToInputArray
) -> Result<()>

This is an overloaded member function, provided for convenience (python) Copies the matrix to another one. When the operation mask is specified, if the Mat::create call shown above reallocates the matrix, the newly allocated matrix is initialized with all zeros before copying the data.

Parameters

• src: source matrix.
• dst: Destination matrix. If it does not have a proper size or type before the operation, it is reallocated.
• mask: Operation mask of the same size as *this. Its non-zero elements indicate which matrix elements need to be copied. The mask has to be of type CV_8U and can have 1 or multiple channels.
