You will need to tell ImageMagick that the format of the image that you are reading is a dng file:

const settings: MagickReadSettings = new MagickReadSettings();
settings.format = MagickFormat.Dng;
await ImageMagick.read(array, settings, async (image) => {
console.log('load image ',image.width,image.height)
