Gulp plugin to optimize images using imageoptim and jpegmini
npm install gulp-imageoptimGulp plugin to optimize images using ImageOptim and JPEGmini.
> Please note this plugin uses ImageOptim-CLI. Unfortunately currently there is no support for Windows and Linux.
So why ImageOptim-CLI? My personal experience and current benchmarks suggest that ImageOptim and ImageAlpha currently outperform alternatives over lossless and lossy optimizations.
``
var gulp = require('gulp');
var imageOptim = require('gulp-imageoptim');
gulp.task('images', function() {
return gulp.src('src/images/*/')
.pipe(imageOptim.optimize())
.pipe(gulp.dest('build/images'));
});

Optimize images using ImageOptim-CLI
To enable JPEGmini support, set the option to true
Type: Boolean
Default: false
Set to false to disable optimize summary in console.
Type: Boolean
Default: true
Batch size
Type: Integer
Default: 100
#### Does Gulp-ImageOptim use JPEGmini?
Yes, however, please note that JPEGmini is a paid-for product. We are using ImageOptim-CLI (ImageOptim and ImageAlpha) without JPEGmini. To use JPEGmini you will need to purchase it.
#### Enabling JPEGmini and support for assistive devices
You may be presented with the following message the first time you run Gulp Imageoptim with the jpegmini flag set to true:
> To automate JPEGmini we need to add Terminal.app (or iTerm.app etc) to the 'support for assistive devices' whitelist.
The JPEGmini OS X Apps don't include a command line API, so a real user is simulated by entering synthetic clicks and keyboard commands instead. This requires your permission and is easily set up in System Preferences as shown by these guides.
+ Enable access for assistive devices in OS X Yosemite.
+ OS X Mavericks: Enable access for assistive devices and applications
#### How do I enable JPEGmini in my gulp task?
`
var gulp = require('gulp');
var imageOptim = require('gulp-imageoptim');
gulp.task('images', function() {
return gulp.src('src/images/*/')
.pipe(imageOptim.optimize({
jpegmini: true
}))
.pipe(gulp.dest('build/images'));
});

#### Can I use this plugin on Windows and Linux?
Unfortunately, ImageOptim and ImageAlpha are not available on those platforms yet.
