heic-decode

Decode HEIC images to extract raw pixel data.

Install

1npm install heic-decode

Usage

Decode the main image in the file:

1const fs = require('fs');
2const { promisify } = require('util');
3const decode = require('heic-decode');
4
5(async () => {
6  const buffer = await promisify(fs.readFile)('/path/to/my/image.heic');
7  const {
8    width,  // integer width of the image
9    height, // integer height of the image
10    data    // Uint8ClampedArray containing pixel data
11  } = await decode({ buffer });
12})();

Decode all images in the file:

1const fs = require('fs');
2const { promisify } = require('util');
3const decode = require('heic-decode');
4
5(async () => {
6  const buffer = await promisify(fs.readFile)('/path/to/my/multi-image.heic');
7  const images = await decode.all({ buffer });
8
9  for (let image of images) {
10    // decode and use each image individually
11    // so you don't run out of memory
12    const {
13      width,  // integer width of the image
14      height, // integer height of the image
15      data    // Uint8ClampedArray containing pixel data
16    } = await image.decode();
17  }
18
19  // when you are done, make sure to free all memory used to convert the images
20  images.dispose();
21})();

Note: when decoding a single image (i.e. using decode), all resources are freed automatically after the conversion. However, when decoding all images in a file (i.e. using decode.all), you can decode the images at any time, so there is no safe time for the library to free resources -- you need to make sure to call dispose once you are done.

When the images are decoded, the return value is a plain object in the format of ImageData. You can use this object to integrate with other imaging libraries for processing.

Note that while the decoder returns a Promise, it does the majority of the work synchronously, so you should consider using a worker thread in order to not block the main thread in highly concurrent production environments.
