Contoh
Code Editor (JavaScript)
// Numbers within range are unaffected.
print('100 clamped to range [0,255]', ee.Number(100).clamp(0, 255)); // 100
// Numbers greater than max in range are set to max.
print('259 clamped to range [0,255]', ee.Number(259).clamp(0, 255)); // 255
// Numbers less than min in range are set to min.
print('-259 clamped to range [0,255]', ee.Number(-259).clamp(0, 255)); // 0
