SilverStripe Image Compress and Cache module

SilverStripe Image Minify Module

SS-image-min is a Silverstripe module for image compressing and server-side caching based on nielse63/php-image-cache., _(*1)

Requirements

SilverStripe Framework 3.0+, _(*2)

Installation

After installing the module by any of the following methods you must build you database by visiting http://yoursite.com/dev/build., _(*3)

Composer

Create a composer.json file:, _(*4)

``` json { "require" : { "encoda/ss-image-min": "~0.1.3" } }, <sub>(*5)</sub>

Navigate to your project root and run the install command.

`$ composer install`

### Github

Navigate to the root directory of your SilverStripe application and execute `git clone https://github.com/encoda/ss-image-min.git`

### Manually

Download [this zip file](https://github.com/encoda/ss-image-min/zipball/master) and extract it in your SilverStripe root directory.

## Usage

Once the module is installed, a compressed cache version of each Silverstripe `Image` instance file is automatically generated by the time it is saved in the database, or (if the module is lately installed in the application and there are already several images in the database) individually at the moment the URL of any of them is called directly or indirectly, by calling either one of its following methods: `getTag`, `getUrl` or `getAbsoluteURL`.

### Example

mysite/code/NarcissisticTeenager.php

``` php
<?php

NarcissisticTeenager extends DataObject {
    ...
    private static $many_many = array(
        'Selfies' => 'Image',
    );

    public function FirstSelfie() {
        return $this->Selfies()->First();
    }
    ...
}

themes/autinpack/templates/Page.ss, <sub>(*6)</sub>

``` ss $GetTag , <sub>(*7)</sub>

## Configuration

SS-image-min doesn't require any configuration.
Although you can overwrite some of them through your `_config.php`.

### Compress Rate

**Default:** `80`

<?php, <sub>(*8)</sub>

SSImageCache::$compress_rate = 70;, <sub>(*9)</sub>

### Increasead Memory Limit

Generating compressed images uses a lot more than the PHP is normally allowed to use. So, by default, SS-image-min increases its memory limit temporarily during the compression processes.

**Default:** '2480M'

<?php, <sub>(*10)</sub>

SSImageCache::$increased_memory_limit = '128M';, <sub>(*11)</sub>

## Cached Image Directory

Change the directory where the generated cached images are saved into.

**Default:** 'ASSETS_PATH . /cache/images'

<?php, <sub>(*12)</sub>

SSImageCache::$image_directory = '/home/user/workspace/project/assets/cached_images'; ```, <sub>(*13)</sub>

Important: The chosen directory must have write rights., <sub>(*14)</sub>
