ee.Array.bitwiseNot
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
以元素為單位，計算輸入內容的位元 NOT，並以可容納輸入內容的最小帶正負號整數型別表示。
範例
程式碼編輯器 (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
