Pipit Imgix is a Perch template filter that enables you to easily manipulate and optimise your images on the fly using Imgix. Imgix also serves your images with a worldwide CDN optimized for visual content.

• Download the latest version of the Pipit Imgix.
• Unzip the download
• Place the PipitTemplateFilter_imgix.class.php file in the folder perch/addons/templates/filters/
• Include the class in the file perch/addons/templates/filters.php:

include('filters/PipitTemplateFilter_imgix.class.php');

Follow Imgix's setup guide and set up your Source.

If you are storing your images on your server along with your Perch installation (i.e. not in cloud storage), create a web folder source and use your root domain as the base URL.

Add your Imgix source subdomain to your Perch config file config.php. If your subdomain is grabapipit.imgix.net, you would add:

define('PIPIT_IMGIX_SUBDOMAIN', 'grabapipit');

By default, the filter does not rewrite your image URLs if you set your Perch production environment to development or staging:

define('PERCH_PRODUCTION_MODE', PERCH_DEVELOPMENT);

You have the option to enable it:

define('PIPIT_IMGIX_DEV', true);

Note that Imgix requires a publicly accessible URL to fetch the image from.

Also note that your Imgix subdomain is tied to a specific location, so unless you are using cloud storage a single subdomain won't work across multiple environments.

Use filter="imgix" on your image field tags to serve the image via Imgix:

<perch:content id="image" type="image" filter="imgix">

Refer to Imgix's documentation for what parameters you can use. You can also use their Sandbox tool to see them in action.

You can add Imgix parameters in 2 ways:

1. Use the imgix-opts or opts attribute and add them all together as if you were to add them to a URL:

<perch:content id="image" type="image" filter="imgix" imgix-opts="auto=format&q=80&w=800">
<perch:content id="image" type="image" filter="imgix" opts="auto=format&q=80&w=800">

2. Or you can add each parameter as a tag attribute prefixed with imgix-:

<perch:content id="image" type="image" filter="imgix" imgix-auto="format" imgix-q="80" imgix-w="800">

You can also use dynamic variables inside the imgix attributes. These are the variables you have access to inside the template:

<perch:content id="quality" type="select" label="Image Quality" options="90,80,70" suppress>
<perch:content id="image" type="image" label="Image" filter="imgix" imgix-opts="auto=format&q={quality}&w=800">

<perch:content id="quality" type="select" label="Image Quality" options="90,80,70" suppress>
<perch:content id="image" type="image" label="Image" filter="imgix" imgix-q="{quality}" imgix-auto="format">

You can specify a subdomain other than the default PIPIT_IMGIX_SUBDOMAIN with the subdomain attribute:

<perch:content id="image" type="image" filter="imgix" imgix-opts="auto=format&q=80&w=800" subdomain="grabapipit">
