how to send image in format Uint8ClampedArray

[guyindepurker]

this is my code:
javascriptBarcodeReader({
/* Image file Path || {data: Uint8ClampedArray, width, height} || HTML5 Canvas ImageData */
image: {data: Uint8ClampedArray.from(res),width: 3333, height: 313},
barcode: 'code-128',
// barcodeType: 'industrial',
})
.then(code => {
console.log('code is',code)
})
.catch(err => {
console.log(err)
})

its print my nothing

my res is the result of base64 image with this:
function convertDataURIToBinary(dataURI) {
var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
var base64 = dataURI.substring(base64Index);
var raw = window.atob(base64);
var rawLength = raw.length;
var array = new Uint8Array(new ArrayBuffer(rawLength));

for(i = 0; i < rawLength; i++) {
array[i] = raw.charCodeAt(i);
}
return array;
}
