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]
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.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]
