Failing to read large files

I’m trying to use Jimp to process images that are about 70-100 MB in size. However, I get the following error

// image is 87.7 MB
Jimp.read('big-image', (err, img) => {
  console.log(err)
})

> Error: maxMemoryUsageInMB limit exceeded by at least 226MB

Is there any way around this?

i found the solutions above would only partially work and further transforms like crop would error

This is what worked for me

const cachedJpegDecoder = Jimp.decoders['image/jpeg']
Jimp.decoders['image/jpeg'] = (data) => {
  const userOpts = { maxMemoryUsageInMB: 1024 }
  return cachedJpegDecoder(data, userOpts)
}

I have same problem. So I tried fix something. [(https://developer.aliyun.com/mirror/npm/package/jpeg-js)] On this site, there are maxMemoryUsageInMB option on decode function.

And I change \node_modules@jimp\core\dist\utils\image-bitmap.js:196 line.

this.bitmap = this.constructor.decoders[_mime](data); to this.bitmap = this.constructor.decoders[_mime](data, {maxMemoryUsageInMB: 2000});

Then I can read the large image. Try this one.
