# Feature: #88602 - Allow registering additional file processors

See [forge#88602](https://forge.typo3.org/issues/88602)

## Description

Registering additional file processors has been introduced.
New processors need to implement the interface `\TYPO3\CMS\Core\Resource\Processing\ProcessorInterface`.

To register a new processor, add the following code to `ext_localconf.php`

```php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['fal']['processors']['MyNewImageProcessor'] = [
    'className' => \Vendor\ExtensionName\Resource\Processing\MyNewImageProcessor::class,
    'before' => ['LocalImageProcessor']
];
```

To order the processors, use `before` and `after` statements. TYPO3 will process the file
with the first processor that is able to process a given task.

## Impact

Developers are now able to provide their own file processing. By providing priorities, the processor ending up handling
the file can be determined on a fine granular level including a fallback.

Examples for custom implementations might be:

-   add a watermark to each image of type png
-   compress uploaded pdf files into zip archives
-   store images that should be cropped at a separate position in the target storage
