class_docstr: Get padding images.
  
  Args:
      stride(int): Stride for calculate pad value for edges.
      padValue(int): Initialization for new area.
code: def __init__(self, stride: int = 8, padValue: int = 128):
      self.stride = stride
      self.padValue = padValue

label_desc: Use image node_id 1 to create a new PadDownRight object  with example: obj = PadDownRight(stride, padValue)
