The output is different between window and mac

[minhquankq]

I have optimized image from the same image and execute on window and mac
Input image 87kb

Output:

• Window image 30.8 kb
• Mac image 32 kb

Expected: the output should be the same.

If you are using the same version of gulp-image and its configuration, the results should be the same as you say. Is there any difference between those configurations? or if they are same, the binaries bundled on gulp-image might (?) be different. So, could you clarify the difference between them?

[minhquankq]

I use the same version (6.1.0) and configuration

const imageOptimizerOptions = {
  pngquant: true,
  optipng: false,
  zopflipng: true,
  jpegRecompress: false,
  mozjpeg: true,
  guetzli: false,
  gifsicle: true,
  svgo: ['--enable', 'cleanupIDs', '--disable', 'convertColors', '--disable', 'removeViewBox'],
  concurrent: 10,
  quiet: true, // defaults to false
};

my gulp tasks are download the images from another repository and gulp-image to optimize the download images. if run again, I will delete the optimized images and download and gulp-image again (to make sure the input of gulp-image will be the same).

• first, I run these gulp tasks on window, then commit the optimized images to git repository.
• second, my teammate runs the same task on mac.

=> the expected is git status should not list any change

but currently, the optimize images was changes (they are different size also), does it depend on OS?

I have checked the version (the image for testing is jpeg)

• gulp-image 6.2.0
• mozjpeg 7.0.0
• jpeg-recompress-bin 5.1.0
  The same version for window and mac.

Also, would you check the version of binaries in node_modules?

[minhquankq]

Sorry for the late response, but what do you mean for binaries in node_modules? in my node_modules doesn't have any binaries dependency

I mean the binaries bundled by each package (mozjpeg, jpeg-recompress-bin) in gulp-image.
