Uint8ClampedArray 到 Uint8Array 到 base64

Question

Is there a similar method of converting a Uint8ClampedArray to a regular array.

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

But then converting from Uint8ClampedArray to Uint8Array?

I understand there are differences in how values are assigned but is rather confusing to look into for me as the Uint8ClampedArray involves an image that is being drawn onto a canvas for which a downloadable blob link is made.

My data looks like this:

And then I try to convert it into base64 with this: https://gist.github.com/enepomnyaschih/72c423f727d395eeaa09697058238727

EDIT: Already tried putting it into the constructor of Uint8Array but when converting to base64 it does not appear to be valid.

new Uint8Array(imageData.data)

Answer 1

我最终使用 canvas.toDataURL 而不是尝试自己转换。
