<class name="ImageFormatLoaderExtension" inherits="ImageFormatLoader" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../class.xsd">
<brief_description>
Base class for creating [ImageFormatLoader] extensions (adding support for extra image formats).
</brief_description>
<description>
The engine supports multiple image formats out of the box (PNG, SVG, JPEG, WebP to name a few), but you can choose to implement support for additional image formats by extending this class.
Be sure to respect the documented return types and values. You should create an instance of it, and call [method add_format_loader] to register that loader during the initialization phase.
