No PDF From Blob

[DevQueen]

My pdf comes in as a byte array. I'm trying to show it using your viewer. My Controller code:

lwsService.getdocument(id) .success(function (response) { var fileName = response[0].FileName; var fileImage = base64ArrayBuffer(response[0].binFileImage); var fileURL = new Blob([fileImage], { type: 'application/pdf' }); $scope.pdfURL = URL.createObjectURL(fileURL);

The code to convert the byte array is:

` function base64ArrayBuffer(arrayBuffer) {
var base64 = ''
var encodings = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'

    var bytes = new Uint8Array(arrayBuffer)
    var byteLength = bytes.byteLength
    var byteRemainder = byteLength % 3
    var mainLength = byteLength - byteRemainder

    var a, b, c, d
    var chunk

    // Main loop deals with bytes in chunks of 3
    for (var i = 0; i < mainLength; i = i + 3) {
        // Combine the three bytes into a single integer
        chunk = (bytes[i] << 16) | (bytes[i + 1] << 8) | bytes[i + 2]

        // Use bitmasks to extract 6-bit segments from the triplet
        a = (chunk & 16515072) >> 18 // 16515072 = (2^6 - 1) << 18
        b = (chunk & 258048) >> 12 // 258048   = (2^6 - 1) << 12
        c = (chunk & 4032) >> 6 // 4032     = (2^6 - 1) << 6
        d = chunk & 63               // 63       = 2^6 - 1

        // Convert the raw binary segments to the appropriate ASCII encoding
        base64 += encodings[a] + encodings[b] + encodings[c] + encodings[d]
    }

    // Deal with the remaining bytes and padding
    if (byteRemainder == 1) {
        chunk = bytes[mainLength]

        a = (chunk & 252) >> 2 // 252 = (2^6 - 1) << 2

        // Set the 4 least significant bits to zero
        b = (chunk & 3) << 4 // 3   = 2^2 - 1

        base64 += encodings[a] + encodings[b] + '=='
    } else if (byteRemainder == 2) {
        chunk = (bytes[mainLength] << 8) | bytes[mainLength + 1]

        a = (chunk & 64512) >> 10 // 64512 = (2^6 - 1) << 10
        b = (chunk & 1008) >> 4 // 1008  = (2^6 - 1) << 4

        // Set the 2 least significant bits to zero
        c = (chunk & 15) << 2 // 15    = 2^4 - 1

        base64 += encodings[a] + encodings[b] + encodings[c] + '='
    }

    return base64
}`

My HTML is:

<pdfviewer src="{{pdfURL}}" on-page-load='pageLoaded(page,total)' id="viewer" load-progress='loadProgress(loaded, total, state)'></pdfviewer>

Nothing displays.
