Reproducing a command using cloning and composition

[fuglede]

I'm trying to reproduce the following command:

convert input.png -colorspace gray \( +clone -blur 0x1 \) +swap -compose divide -composite -linear-stretch 5%x0% output.png

As far as I can tell, linear-stretch isn't available, but contrast-stretch is. What I've tried is the below (and I've tried with DiviceDst instead of DivideSrc as well), but the result doesn't match what I get on the command line:

        ImageMagick.read(array, image => {
          image.colorSpace = ColorSpace.Gray
          image.clone(clone => {
            clone.blur(0, 1)
            image.composite(clone, CompositeOperator.DivideSrc)
            image.contrastStretch(new Percentage(5), new Percentage(0))
            image.rotate(1.5)
            const canvas = document.getElementById('canvas')
            image.writeToCanvas(canvas)
          })

What am I doing wrong?

Edit: Actually, it's close enough that it's probably just the difference between the stretching methods, so let me not worry more about that. I'd delete the thread entirely if that was possible. :)

Support for linear-stretch will become available in the next release.

Thanks for the heads-up, that's great!
