ee.Array.bitwiseOr

  • Array.bitwiseOr() calculates the bitwise OR of two input arrays element-by-element.

  • It takes two arrays, left and right, as input and returns a new array with the results.

  • The bitwise OR operation is performed on corresponding elements of the input arrays.

  • The function works with numeric arrays and supports various data types.

  • It handles empty arrays gracefully, returning an empty array if either input is empty.

 On an element-wise basis, calculates the bitwise OR of the input values.

UsageReturns
Array.bitwiseOr(right)Array
ArgumentTypeDetails
this: leftArrayThe left-hand value.
rightArrayThe right-hand value.

Examples

Code Editor (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]
