**Disclaimer:**\\

The license for **System.Drawing.Managed** **does not include** or grant any rights to use the underlying **ImageSharp** libraries or classes directly. While **System.Drawing.Managed** internally includes portions of **ImageSharp** for rendering and imaging functionality, these are provided strictly as an **implementation detail**.

Any **direct use** of `SixLabors.ImageSharp` or other **SixLabors** libraries must be licensed **directly from** [**SixLabors**](https://sixlabors.com/) and should be performed using their official **NuGet packages**.

Developers must not reference or rely on internal ImageSharp types exposed through reflection or by bypassing the public `System.Drawing` API.
