ee.Array.bitwiseAnd

按元素计算输入值的按位 AND。

用法返回
Array.bitwiseAnd(right)数组
参数类型详细信息
此：left数组左侧值。
right数组右侧值。

示例

代码编辑器 (JavaScript)

var empty = ee.Array([], ee.PixelType.int8());
print(empty.bitwiseAnd(empty));  // []

print(ee.Array(0).bitwiseAnd(ee.Array(0)));  // 0
print(ee.Array(0).bitwiseAnd(ee.Array(1)));  // 0
print(ee.Array(1).bitwiseAnd(ee.Array(0)));  // 0
print(ee.Array(1).bitwiseAnd(ee.Array(1)));  // 1
print(ee.Array(0xFF).bitwiseAnd(ee.Array(0xFFFF)));  // 255
print(ee.Array(0xFFFF).bitwiseAnd(ee.Array(0xFF)));  // 255

print(ee.Array(-1).bitwiseAnd(ee.Array(0xFF)));  // 255
print(ee.Array(-1).bitwiseAnd(ee.Array(-2)));  // -2

print(ee.Array([6, 6]).bitwiseAnd(ee.Array([1, 11])));  // [0,2]

import ee
import geemap.core as geemap

Colab (Python)

empty = ee.Array([], ee.PixelType.int8())
display(empty.bitwiseAnd(empty))  # []

display(ee.Array(0).bitwiseAnd(ee.Array(0)))  # 0
display(ee.Array(0).bitwiseAnd(ee.Array(1)))  # 0
display(ee.Array(1).bitwiseAnd(ee.Array(0)))  # 0
display(ee.Array(1).bitwiseAnd(ee.Array(1)))  # 1
display(ee.Array(0xFF).bitwiseAnd(ee.Array(0xFFFF)))  # 255
display(ee.Array(0xFFFF).bitwiseAnd(ee.Array(0xFF)))  # 255

display(ee.Array(-1).bitwiseAnd(ee.Array(0xFF)))  # 255
display(ee.Array(-1).bitwiseAnd(ee.Array(-2)))  # -2

display(ee.Array([6, 6]).bitwiseAnd(ee.Array([1, 11])))  # [0, 2]
