ini: input | Array | Array input. |
Contoh
Code Editor (JavaScript)
// Clamps below at 0.
print(ee.Array([-1]).byte()); // [0]
print(ee.Array([255]).byte()); // [255]
// Clamps above at 255.
print(ee.Array([256]).byte()); // [255]
// Rounds. [0,0,1,127,255,255]
print(ee.Array([-0.1, 0.1, 0.5, 127.1, 255.1, 255.9]).byte());
// Requires an explicit PixelType if no data.
print(ee.Array([[], []], ee.PixelType.float()).byte()); // Empty [[], []]
