When you use input file, you can get base64 string as array without worrying about orientation of exif.

Usage

$ npm install exif-rotate-js

getBase64Strings(files, {maxSize})

return

return is string of base64 array like ["data:image/jpeg;base64,/9j/4AAQS..."]

files

files is input target files. User can select multiple files.

maxSize

default: 720

maxSize is canvas max size. When image's width is greater than height, maxSize applies to width. And vice versa.

Example

import { getBase64Strings } from 'exif-rotate-js/lib';

const elem = document.getElementById('fileImage');

if (elem) {
  elem.onchange = async e => {
    if (!e.target) return;
    const data = await getBase64Strings(e.target.files, { maxSize: 1024 });
    console.log(data); // ["data:image/jpeg;base64,/9j/4AAQS..."] as type of Array
  };
}
