While it is possible to check for the presence of the GD plugin via composer require ext-gd, this does not ensure that specific format support is enabled. This Composer plugin allows you to specify a set of required formats for GD and will verify that they are enabled after composer install has run.

If these formats are not enabled, Composer will output the issue on the command line.

Configuration

This plugin ships with a default set of required formats that it checks for.

FreeType
JPEG
PNG
WebP

To override these defaults, include configuration in your composer.json file:

"extra": {
  "php-gd-config-check": {
      "required-formats": [
          "JPEG Support",
          "PNG Support"
      ]
}
