.. py:class:: SampleComparator

   Image comparator that uses nuke.sample for processing image data.

   This comparison is quite slow. It needs to compute the full image of both nodes.


   .. py:method:: assert_equal(node_a: nuke.Node, node_b: nuke.Node) -> None
      :staticmethod:


      Assert that both nodes output the same pixels.

      :param node_a: first test node.
      :param node_b: second test node.

      :raises AssertionError: the two nodes are not equal based on the testing criteria.
