以元素为单位，计算输入值的按位 OR。
| 用法 | 返回 |
|---|
Array.bitwiseOr(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.bitwiseOr(empty)); // []
print(ee.Array(0).bitwiseOr(ee.Array(0))); // 0
print(ee.Array(0).bitwiseOr(ee.Array(1))); // 1
print(ee.Array(1).bitwiseOr(ee.Array(0))); // 1
print(ee.Array(1).bitwiseOr(ee.Array(1))); // 1
print(ee.Array(0xFF).bitwiseOr(ee.Array(0xFFFF))); // 65535
print(ee.Array(0xFFFF).bitwiseOr(ee.Array(0xFF))); // 65535
print(ee.Array(-1).bitwiseOr(ee.Array(0xFF))); // -1
print(ee.Array(-2).bitwiseOr(ee.Array(-3))); // -1
print(ee.Array(-2).bitwiseOr(ee.Array(-4))); // -2
print(ee.Array([6, 6]).bitwiseOr(ee.Array([1, 11]))); // [7,15]
Python 设置
如需了解 Python API 和如何使用 geemap 进行交互式开发，请参阅
Python 环境页面。
import ee
import geemap.core as geemap
Colab (Python)
empty = ee.Array([], ee.PixelType.int8())
display(empty.bitwiseOr(empty)) # []
display(ee.Array(0).bitwiseOr(ee.Array(0))) # 0
display(ee.Array(0).bitwiseOr(ee.Array(1))) # 1
display(ee.Array(1).bitwiseOr(ee.Array(0))) # 1
display(ee.Array(1).bitwiseOr(ee.Array(1))) # 1
display(ee.Array(0xFF).bitwiseOr(ee.Array(0xFFFF))) # 65535
display(ee.Array(0xFFFF).bitwiseOr(ee.Array(0xFF))) # 65535
display(ee.Array(-1).bitwiseOr(ee.Array(0xFF))) # -1
display(ee.Array(-2).bitwiseOr(ee.Array(-3))) # -1
display(ee.Array(-2).bitwiseOr(ee.Array(-4))) # -2
display(ee.Array([6, 6]).bitwiseOr(ee.Array([1, 11]))) # [7, 15]
