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 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.
