README

Image optimization of images for Flow and Neos using the imagemin-cli or other tools.

This package is inspired by MOC.ImageOptimizer https://packagist.org/packages/moc/imageoptimizer and Sitegeist.Origami https://github.com/sitegeist/Sitegeist.Origami that basically perform the same task.

Deviations from the previously mentioned packages:

All mediaTypes that shall be optimized have to be enabled explicitly.
Imagemin-cli is used by default for all enabled media types but can be replaced as needed.
Does not need a jobqueue like Sitegeist.Origami did because async thumbnails are nowadays default.
Local temporary files that are later imported should support cloud storages (not tested yet).
Temorary files with file extensions allow to use tools that rely on file extensions.

Installation

Sitegeist.Iconoclasm is available via packagist. Just add "sitegeist/iconoclasm" to the require section of the composer.json or run composer require sitegeist/iconoclasm. We use semantic-versioning so every breaking change will increase the major-version number.

In addition to the Flow Package the imagemin-cli and all plugins or other tools have to be available on the server. You can install the libraries globally using npm:

npm install --global imagemin-cli imagemin-pngquant imagemin-webp imagemin-mozjpeg

You can also install the packages into a dedicated folder instead globally. In this case you will have to configure the imegemin command with full pathes like /your/folder/node_modules/imagemin-cli/cli.js

npm install --prefix /your/folder imagemin-cli imagemin-pngquant imagemin-webp imagemin-mozjpeg

!!!Please verify the that the cli tools work by executing each plugin separately. Especially the imagemin-webp tool sometimes requires additional libraries!!!

Configuration

Using the Sitegeist.Iconoclasm configuration, the used command can be configured. The mediaTypes section allows to enable certain types and allows to override the global command for this type.

Sitegeist:
  Iconoclasm:

    #
    # The imagemin cli command, you may want to configure an explicit path here for your server
    #
    # The tool can be installed npm install --global imagemin-cli imagemin-pngquant imagemin-webp imagemin-mozjpeg imagemin-svgo
    #
    command: 'imagemin {input} > {output}'

    #
    # The media types that are to be optimized
    #
    # Each media type has to be enabled for optimizing. In case specific options or even 
    # an different command shall be used the global `command` can be overwritten for each type.
    #
    mediaTypes:
      'image/jpeg':
        enabled: true
        command: 'imagemin {input} --plugin=mozjpeg > {output}'

      'image/png':
        enabled: true
        command: 'imagemin {input} --plugin=pngquant > {output}'

      'image/webp':
        enabled: true
        command: 'imagemin {input} --plugin=webp > {output}'

      'image/gif':
        enabled: false

      'image/svg':
        enabled: false
