ee.Array.byte

AI-generated Key Takeaways

• The byte() method casts input values to an unsigned 8-bit integer on an element-wise basis.

• Values below 0 are clamped to 0, and values above 255 are clamped to 255.

• The byte() method rounds input values.

• An explicit PixelType is required if there is no data in the input array.

On an element-wise basis, casts the input value to an unsigned 8-bit integer.

Usage	Returns
Array.byte()	Array

Argument	Type	Details
this: input	Array	The input array.

Examples

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 [[], []]
