将Uint8ClampedArray转换为常规数组

Question

如何将Uint8ClampedArray （如用于存储HTML5画布图像数据的那个）转换为常规数组，其中值不会被约束为0 - 255 ？

Answer 1

You can convert a typed array to a regular array by using Array.prototype.slice

var typedArray = new Uint8ClampedArray([1, 2, 3, 4]);
var normalArray = Array.prototype.slice.call(typedArray);

Also if using ES6 you may be able to use Array.from instead:

var normalArray = Array.from(typedArray);
