.. py:function:: compute_negative_tree_pixels(tree: hats.pixel_tree.pixel_tree.PixelTree) -> list[hats.pixel_math.HealpixPixel]

   
   Computes a 'negative pixel tree' consisting of the pixels needed to cover the full sky not in the tree


   :Parameters:

       **tree** : PixelTree
           the input tree to compute the negative of



   :Returns:

       list[HealpixPixel]
           A list of HEALPix pixels needed to cover the part of the sky not covered by the tree, using the least
           number of pixels possible.
