Image resizer and fix exif rotate

This module fix rotate and resize your image.

import resizer from 'image-resizer-js';

resizer(image<Uint8Array | ArrayBuffer>, maxWidth<Number>, quality<Number 0..100>, rotate<Number 0..3>)
  .then(image<ArrayBuffer> => {
    // image resized
    const blob = new Blob([image]);

    image.src = blob;
  })
  .catch(err => console.error(err))

Or with more options...

import resizer from 'image-resizer-js';

const options = {
  maxWidth: <Number | undefined>,
  maxHeight: <Number | undefined>,
  quality: <Number 0..100 | undefined>,
  rotate: <Number 0..3 | undefined>,
  type: <String>,
  silent: <Boolean>
}

resizer(image<Uint8Array | ArrayBuffer>, options)
  .then(image<ArrayBuffer> => {
    // image resized
    const blob = new Blob([image]);

    image.src = blob;
  })
  .catch(err => console.error(err))

Where the options.silent is active, no logs is return if you have an error or other.

Where the options.type is the mime type of the resulting image. The mime type defaults to image/png so you may want to specify images/jpeg.

Example

From a fetched image

import resizer from 'image-resizer-js';

fetch('my-image.jpg')
  .then(res => res.arrayBuffer())
  .then(buffer => resizer(buffer, undefined, 50))
  .then(buffer => {
    const blob = new Blob([buffer]);
    const image = new Image():

    image.src = URL.createObjectURL(blob);

    // ...
  })
