Convert Uint8ClampedArray to regular array

How can I convert a Uint8ClampedArray (like one used for storing HTML5 canvas image data) to a regular array, in which values won't be constrained to 0-255?

Solution

  • 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);
