# System Requirements

# General requirements

• Craft CMS 3 or greater
• PHP 7.0 or newer compiled with GD (or GD 2) library
  • ImageMagick is also supported if installed
• MySQL 5.5+ (with InnoDB) or PostgreSQL 9.5+
• At least 256 megabytes of memory allocated and available to PHP
  • 512 megabytes is recommended (and more if you can spare it). Manipulating images can take a lot of memory. And particularly, the larger image, the more memory it will take.

# Control panel interface and entry field type use requirements

• Edge 41 or greater
• Internet Explorer 11 or greater
• Chrome (tested on version 65)
• Firefox (tested on version 59)
• Safari (Mac) (tested on version 11)

# Image optimization requirements

Ansel will also utilize various image optimization libraries if they are installed on the server and your PHP version is high enough.

• PHP 5.5 or greater
• jpegoptim for jpeg optimization
• gifsicle for gif optimization
• optipng for PNG optimization

# Installing And Licensing Ansel

Installing and updating Ansel for Craft can be done in 1 of 2 ways:

# Composer

For those who are comfortable with and/or prefer the command line, you can install via Composer directly:

composer require buzzingpixel/ansel-craft

After installing via composer, go to your Craft CP > Settings > Plugins and install Ansel.

# Craft Plugin Store

The other way, of course, is through the plugin store.

Use the plugin store in your Craft Control Panel to install Ansel.

# Buying Ansel

Either way, buying and licensing of Ansel for Craft is handled through Craft’s plugin store. A site license is $79. Yearly renewals to access updates and support are $29.

# Upgrading from Ansel 1.x

Follow the update instructions for updating Craft CMS using the Craft CMS documentation. Once you have completed that, you can install Ansel. If you install Ansel via the command line with Composer, be sure to visit a CP page which will run some required schema updates.

You’ll also probably need to do some template updating:

• .all() must be called to loop through ansel images (or use .one() to get a single image)
• .first() and .find() must be replaced with .one() and .all() respectively.

# Configuring

Ansel has a few settings you may want to look at before diving in to making your Ansel fields.

# Config file only options

There are a couple of configuration options that can only be set in the config file.

# optimizerShowErrors

Normally the optimizer for jpegoptim, gifsicle, and optipng will fail silently. However, it can sometimes be useful to know if something is going wrong — for instance, when you install the tools on your server and want to make sure they are working. If the optimizer is not able to find the tools or they return an error code when trying to optimize the image, when this config setting is set to true, the optimizer will throw an error for you to see.

'optimizerShowErrors' => true;

# disableOptipng

Disables optipng optimization.

'disableOptipng' => true;

# disableJpegoptim

Disables jpegoptim optimization.

'disableJpegoptim' => true;

# disableGifsicle

Disables gifsicle optimization.

'disableGifsicle' => true;
