code: def xy(
      transform, rows, cols, zs=None, offset="center", **rpc_options
  ):
      """Get the x and y coordinates of pixels at `rows` and `cols`.
  
      The pixel's center is returned by default, but a corner can be returned
      by setting `offset` to one of `ul, ur, ll, lr`.
  
      Supports affine, Ground Control Point (GCP), or Rational Polynomial
      Coefficients (RPC) based coordinate transformations.
  
      Parameters
      ----------
      transform : Affine or sequence of GroundControlPoint or RPC
          Transform suitable for input to AffineTransformer, GCPTransformer, or RPCTransformer.
      rows : list or int
          Pixel rows.
      cols : int or sequence of ints
          Pixel columns.
      zs : list or float, optional
          Height associated with coordinates. Primarily used for RPC based
          coordinate transformations. Ignored for affine based
          transformations. Default: 0.
      offset : str, optional
          Determines if the returned coordinates are for the center of the
          pixel or for a corner.
      rpc_options : dict, optional
          Additional arguments passed to GDALCreateRPCTransformer.
  
      Returns
      -------
      xs : float or list of floats
          x coordinates in coordinate reference system
      ys : float or list of floats
          y coordinates in coordinate reference system
