right | 数组 | 右侧值。 |
示例
代码编辑器 (JavaScript)
var empty = ee.Array([], ee.PixelType.int8());
print(empty.or(empty)); // []
print(ee.Array([0, 0, 1, 1]).or(ee.Array([0, 1, 0, 1]))); // [0,1,1,1]
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.Or(empty)) # []
# [0, 1, 1, 1]
display(ee.Array([0, 0, 1, 1]).Or(ee.Array([0, 1, 0, 1])))
