| def quadtree.Quadtree.Quadtree.Node.__getitem__ | ( | self, | ||

Allows access to a node's pixel data with the notation node[x, y].
| p | A tuplet (x, y) contaning coordinates. |

| tree, | ||||
| grid, | ||||
| corner, | ||||
| dims, | ||||
| parent, | ||||
| corner_index | ||||
| ) |
Constructs a new node.
| tree | The quad tree containing this node | |
| grid | The raw data in an enhanced_grid | |
| corner | An x,y tuplet denoting the top-left corner of the region that this node represents. | |
| dims | An x, y, tuplet denoting the dimensions of the region that this node represents. |

| def quadtree.Quadtree.Quadtree.Node.count | ( | self, | ||
count_self = True | ||||
| ) |
Counts the nodes from this node downwards.
If count_self is False, only leaf nodes are counted. If count_self is True, all children nodes including this node will be counted. Otherwise, only leaf nodes are counted.

| def quadtree.Quadtree.Quadtree.Node.interpolate | ( | self, | ||

Similar to __getitem__ but returns an interpolated value instead.
The Measure used for this Quadtree must implement the blend method for this method to work.

Similar to __getitem__ but returns an interpolated value instead.
The Measure used for this Quadtree must implement the blend method for this method to work. This interpolation is better than that provided by interpolate.

| def quadtree.Quadtree.Quadtree.Node.is_left_node | ( | self | ) |
These functions are used to find neighnoring nodes.
It is not a very good way to do it - for instance, a better way to find the left node neighbor is
node[self.x - 1, y]
