ee.Array.bitwiseNot
Stay organized with collections
Save and categorize content based on your preferences.
On an element-wise basis, calculates the bitwise NOT of the input, in the smallest signed integer type that can hold the input.
| Usage | Returns | Array.bitwiseNot() | Array |
| Argument | Type | Details | this: input | Array | The input array. |
Examples
Code Editor (JavaScript)
var empty = ee.Array([], ee.PixelType.int8());
print(empty.bitwiseNot()); // []
print(ee.Array(0).bitwiseNot()); // -1
print(ee.Array(1).bitwiseNot()); // -2
print(ee.Array(0xFF).bitwiseNot()); // -256
print(ee.Array(-1).bitwiseNot()); // 0
print(ee.Array(-2).bitwiseNot()); // 1
print(ee.Array(-3).bitwiseNot()); // 2
print(ee.Array(0xFF).toInt64().bitwiseNot()); // -256
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.bitwiseNot()) # []
display(ee.Array(0).bitwiseNot()) # -1
display(ee.Array(1).bitwiseNot()) # -2
display(ee.Array(0xFF).bitwiseNot()) # -256
display(ee.Array(-1).bitwiseNot()) # 0
display(ee.Array(-2).bitwiseNot()) # 1
display(ee.Array(-3).bitwiseNot()) # 2
display(ee.Array(0xFF).toInt64().bitwiseNot()) # -256
