ee.Array.bitsToArray
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
將整數的位元轉換為陣列。陣列的元素數量與最高位元的位置相同，如果值為 0，則陣列只會有一個 0。

ee.Array.bitsToArray(input) | 陣列 |
範例
程式碼編輯器 (JavaScript)
print(ee.Array.bitsToArray(0)); // [0]
print(ee.Array.bitsToArray(1)); // [1]
print(ee.Array.bitsToArray(5)); // [1, 0 , 1]
print(ee.Array.bitsToArray(0xFF)); // [1,1,1,1,1,1,1,1]
print(ee.Array.bitsToArray(-1)); // Array of 64 "1" values
print(ee.Array.bitsToArray(-1).toInt8()); // Array of 64 "1" values
