Twig Image Base64 Encoding

A simple Twig extension to create base64-encoded strings from Craft [Image] Assets in your Twig templates.

Requirements

This Twig extension requires that you pass an instance of a Craft Asset in your Twig template. The extension will die gracefully if anything other than that is passed in as the first parameter.

Usage

Base64-encode asset

As a Twig Function

With default options

{{ image64(asset) }}

With inline set to true

{{ image64(asset, true) }}

This will return the base64-encoded string in a data URI scheme. The default value is false.

As a Twig Filter

{{ asset|image64 }}

Base64-encode thumbnail

As a Twig Function

With default options

{{ thumb64(asset) }}

With inline set to true and width to 200px

{{ thumb64(asset, 200, true) }}

Second parameter is thumbnail width, default to 100px; Setting third parameter to true will return the base64-encoded string in a data URI scheme. The default value is false.

As a Twig Filter

{{ asset|thumb64 }}
