imagemin-jpeg-recompress's Issues

index.js missing from npm

My script failed to load this module. It turns out http://registry.npmjs.org/imagemin-jpeg-recompress/-/imagemin-jpeg-recompress-0.2.0.tgz does not contain index.js. After I wget the file from GitHub, npm build-main succeeds. Did you miss something?

Photoshop intergration

Hi there,

Great software you have there. was wondering if possible to integrate it as a script in photoshop somehow to save work time?

Failed working with large numbers of JPGs

I tried to use jpeg-recompress on a directory consists of hundreds of thousands images. The directory size around 15 GB. I use Linux and Debian 9.
The command:

find /path/dir -type f -name '*.jpg' | xargs -P 50 -I {} jpeg-recompress --quality high --min 60 --method smallfry --strip {} {} ;

The command will result jpeg-recompress on HALT and shell session terminated after around 30 minutes.
Anyone can suggest me better line to work with huge directory?

Use imagemin-jpeg-recompress in the grunt-contrib-imagemin workflow

I tried to configure this plugin in my grunt workflow but it's not working.

module.exports = function(grunt, options ) {
  'use strict';
  var jpegRecompress = require('imagemin-jpeg-recompress');
  return {
    options: {
      optimizationLevel: 3,
      use: [jpegRecompress({ loops: 3 })]
    },
    dev: {
      files:[
          {
            expand: true,
            cwd: 'src/',
            src:['**/*.{png,jpg,gif}'],
            dest: 'dest'
        }
      ]
    }
  };
};

but it raising an error

Fatal error: Object #<Object> has no method 'apply'

It looks like the imagemin is expecting a function but the plugin is returning an object ( probably a stream ?). Do the imagemin apis has changed lately ?
Unfortunately I haven't had time yet to go deep in the code/problem.
Any ideas? Thanks

Always get an error

It seems that image has been optimized, but error is still thrown and process will exit.

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: ssim at q=50 (40 - 60): 0.996457

ssim at q=59 (59 - 60): 0.997369
ssim at q=60 (60 - 60): 0.997396
Final optimized ssim at q=61: 0.997048
New size is 47% of original (saved 63 kb)

How are quality presets and min/max settings related?

It's unclear from the documentation how these options are related. If I choose the "high" quality preset, does that have any effect on the min/max compression options? E.g. if the high quality preset is used, does that mean that the min is set at 60 rather than the default (40)?

I want to use this plugin, because it as a better compression.

Handle larger output file better

It took me a while to figure out why jpeg-recompress suddenly stopped generating output files. It turns out that, if the settings cause the output file to be larger than the input file (which can happen with default settings), jpeg-recompress prints an error and has an exit status of 1. However, imagemin-jpeg-recompress only throws an obscure "Command failed" in this case. It would be nice if you could detect it.

TypeError: pipe.then is not a function

const imagemin = require('imagemin');
const imageminJpegRecompress = require('imagemin-jpeg-recompress');

var path = process.argv[2];
var out = process.argv[3];

imagemin([path], out, {
    plugins: [
        imageminJpegRecompress()
    ]
}).then(files => {
    console.log(files);
    console.log("finished");
}).catch(err => {
    console.log("ERR:"+err);
    throw err;
});

I am getting this error when launching : node myscript.js .
I have seen this error already in similar plugins (imagemin/imagemin-webp#8), is it related?

Output file is larger than input, aborting!

Hello!
I use use gulp-image package with imagemin-jpeg-recompress plugin to optimize mutiple files:

gulp.task('images', config.img.description, wrapPipe(function (success, error) {
	return gulp
		.src(config.source, config.options)
		.pipe(imagemin([
			imageminJpegRecompress({ quality: 'low' })
		]).on('error', error))
		.pipe(gulp.dest(config.destination))
		.on('end', () => {
			notifier('Images have been minified.');
		}, success);
}));

If we get at least one non-optimizable file during processing, all output piping will be aborted:

[15:04:26] 'images' errored after 725 ms
[15:04:26] Error in plugin 'gulp-imagemin'
Message:

    timedOut: false
    fileName: /full_file_name_is_here.jpg

How can I continue piping and just copy non-optimized file as-is to destination in this case?
Thank you.

CMYK support

Hi,

Great job with this plugin. Just wandering if there is support for CMYK jpgs. I get an error : Unsupported color conversion request

Cheers

doesn't work on DigitalOcean dokku

work perfectly when i test it on localhost, but when i deploy to Digital Ocean compress dosesn't work.I am Using it with multer

      app.use( multer({ dest: './uploads/',
      limits: {

          fileSize : 10 * 1024 * 1024,
          fieldNameSize: 100,
          files: 5,
          fields: 8

      },

      onFileUploadComplete: function (file) {

          console.log( file.path+ ' upload complete');

          var imagemin = new Imagemin()
              .src(file.path)
              .dest(file.path)
              .use(jpegRecompress({
                  progressive: true,
                  loops: 7,
                  min: 30,
                  strip: true,
                  quality : 'low',
                  target : 0.7
              }));

          imagemin.optimize();
      },
      onFileUploadStart: function (file) {

      },
      onFileSizeLimit: function (file) {
          console.log('Failed: ToBiggZ')

      },
      onFilesLimit: function () {
          console.log('Crossed file limit!')
      },
      onError: function (error, next) {
          console.log(error)
          next(error)
      }
  }
));

Is there a way to provide an array of files with wildcards?

Right now it looks like I can only run this plugin on a per file basis, but I want it to do some pattern matching (like most plugins used with grunt).

Is that at all possible right now?

If not, can it be added?

I'm looking for a pattern like so:

files: [{
    expand: true,
    cwd: 'img/',
    src: ['*.jpg', 'projects/*.jpg'],
    dest: 'img/_build'
}]

not optimized = no output

When an image is already optimized or has, for example, 15Mpx dimensions and 0.5Mb filesize, jpeg-compress aborts.
So if I use gulp-imagemin, there's no output image, as exec-buffer throws an error for it.
It would be great, if you pass original image in such cases.

`GLIBC_2.14' not found (Debian 7.6)

I get the following when trying to save with this plugin:

 /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found

The output of running libc.so.6:

GNU C Library (Debian EGLIBC 2.13-38+deb7u3) stable release version 2.13

Using the latest version of libc6 from apt-get. Is it the case that I can't use it with my version of Debian?
