Hi there 👋

blob-image-convert's Issues

Uncaught TypeError: blob.ToPNG is not a function

<script type="text/javascript">
const b64toBlob = (b64Data, contentType='', sliceSize=512) => {
const byteCharacters = atob(b64Data);
const byteArrays = [];

for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
  const slice = byteCharacters.slice(offset, offset + sliceSize);

  const byteNumbers = new Array(slice.length);
  for (let i = 0; i < slice.length; i++) {
    byteNumbers[i] = slice.charCodeAt(i);
  }

  const byteArray = new Uint8Array(byteNumbers);
  byteArrays.push(byteArray);

const blob = new Blob(byteArrays, {type: contentType});

//USAGE
var mime_type = '{{get_blob_instance.mime_type}}'

var blobUrl = URL.createObjectURL(blob)
