Description

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?

Research direction
Investigate the 'maxMemoryUsageInMB limit exceeded' error in Jimp's source code. Look for configuration options to increase the limit or implement streaming/lazy loading for large images. Check if there is a way to pass options to Jimp.read() to override the memory limit. Also review comments in the issue for any workarounds or proposed solutions.
