Javascript Uint8ClampedArray Type
Introduction
A Uint8ClampedArray object describes an array-like view of an underlying binary data buffer.
The constructors are listed as follows:
new Uint8ClampedArray(); new Uint8ClampedArray(length); new Uint8ClampedArray(typedArray); new Uint8ClampedArray(object); new Uint8ClampedArray(buffer [, byteOffset [, length]]);
| Parameter | Optional | Meaning |
|---|---|---|
| length | Required | an internal array buffer is created of size length multiplied by BYTES_PER_ELEMENT bytes. |
| typedArray | Required | the typedArray is copied into a new typed array. |
| object | Required | use the Uint8ClampedArray.from() method. |
| buffer | Required | create from buffer |
| byteOffset | optional | offset to start |
| length | optional | length to copy |
Property access
You can reference elements in the array using standard array index syntax.
var int16 = new Int16Array(2); int16[0] = 42;//ww w . ja v a2 s .com console.log(int16[0]); // 42
| Type | Value Range | Size in bytes | Description | Equivalent C type |
|---|---|---|---|---|
| Uint8ClampedArray | 0 to 255 | 1 | 8-bit unsigned integer (clamped) | uint8_t |
