On an element-wise basis, returns 0 if the input is non-zero, and 1 otherwise.
| Usage | Returns | Array.not() | Array |
| Argument | Type | Details | this: input | Array | The input array. |
Examples
Code Editor (JavaScript)
var empty = ee.Array([], ee.PixelType.int8());
print(empty.not()); // []
print(ee.Array([0]).not()); // [1]
print(ee.Array([1]).not()); // [0]
print(ee.Array([-1, -0.1, 0, 0.1, 1]).not()); // [0,0,1,0,0]
Python setup
See the
Python Environment page for information on the Python API and using
geemap for interactive development.
import ee
import geemap.core as geemap
Colab (Python)
empty = ee.Array([], ee.PixelType.int8())
display(empty.Not()) # []
display(ee.Array([0]).Not()) # [1]
display(ee.Array([1]).Not()) # [0]
display(ee.Array([-1, -0.1, 0, 0.1, 1]).Not()) # [0, 0, 1, 0, 0]
