Neos CMS optimization of JPEGs for Google PageSpeed

As Google PageSpeed docs suggests to increase the Google PageSpeed, this Neos CMS plugin changes the sampling factor of images to 4:2:0 while resizing.

Works very well in addition to moc/imageoptimizer.

Supported Imagine drivers:

• Imagick (ImageMagick)

Install

Install with composer

composer require vivomedia/neos-jpeg-pagespeed-optimization 

If you want to change all already created images, you have to clear all thumbnails and the cache.

./flow media:clearthumbnails
./flow flow:cache:flush --force

Configuration

If you want to disable the image optimization in development context, you can set up following configuration in your /Configuration/Development/Settings.yaml

VIVOMEDIA:
  GooglePageSpeed:
    JpegOptimization:
      enabled: false

TODO

Imgine drivers:

• Gmagick (GraphicsMagick)
