Usage in Umbraco

To use in Umbraco, you must inject the configuration in an appropriate manor, eg. in a Composer.

using Umbraco.Cms.Core.Composing;

namespace MyUmbracoProject;

public class PdfFormatComposer : IComposer
{
    public void Compose(IUmbracoBuilder builder)
    {
        var config = SixLabors.ImageSharp.Configuration.Default.Clone();
        config.Configure(new ImageSharpCommunity.Formats.Pdf.PdfConfigurationModule());
    }
}

This will be picked up by Umbraco when starting the website, and adds the necessary configuration.
