| def quadtree_image.ChannelMeasure.aproximate | ( | self, | ||
| grid, | ||||
| corner, | ||||
| dims | ||||
| ) |
Aproximates the region of the grid between corner and corner+dims.
The return type must be the same as the data content type of the tree's node in which this AbstractMeasure is used.

| def quadtree_image.ChannelMeasure.blend | ( | self, | ||
| col1, | ||||
| col2, | ||||
| ratio | ||||
| ) |
Blends two node values.
Ratio is a value between 0 and 1. If it is 0, the second value is returned. If it is 1, the first value is returned.

| def quadtree_image.ChannelMeasure.blend3 | ( | self, | ||
| col1, | ||||
| col2, | ||||
| col3, | ||||
| ratio1, | ||||
| ratio2, | ||||
| ratio3 | ||||
| ) |
Blends three node values.
The three ratios must add up to 1. If the three ratios are 0 1 0, the result is the same as the second value.

| def quadtree_image.ChannelMeasure.detail | ( | self, | ||
| grid, | ||||
| corner, | ||||
| dims, | ||||
| bias | ||||
| ) |
Measures the detail of the region of the grid between the points corner and corner+dims.
Returns a value between 0 and 1. (0 is no detail, 1 is full detail). The bias can be ignored - it is the ratio of cells to the entire grid represented by the piece of node.
- Todo:
- Remove bias: can be calculated from grid.dims and dims!
