Optimised images for Silverstripe

A module to automatically optimise/compress uploaded as well as any resampled (cropped, scaled etc) images in Silverstripe. Images (JPG, PNG & GIF) are automatically optimised, provided you have the correct binaries installed (see "Installation" below).

The module overrides the default FlysystemAssetStore to and transparently optimises the image before adding the image to the store.

Requirements

• silverstripe/framework ^4.0 || ^5.0
• silverstripe/assets ^1.10 || ^2.0
• spatie/image-optimizer - automatically installed
• JpegOptim, Optipng, Pngquant 2 & Gifsicle binaries (see below)

Optimisation tools

The module uses spatie/image-optimizer and will use the following optimisers if they are both present and in your default path on your system:

• JpegOptim
• Optipng
• Pngquant 2
• Gifsicle

Installation

composer require axllent/silverstripe-image-optimiser

Installing the utilities on Ubuntu:

sudo apt-get install jpegoptim optipng pngquant gifsicle

Installing the utilities on Alpine Linux:

apk add jpegoptim optipng pngquant gifsicle

Usage

Assuming you have the necessary binaries installed, it should "just work" with the default settings once you have flushed your Silverstripe installation.

For custom optimisation settings, please refer to the Configuration documentation.
