如何导入MagickImage

using ImageMagick;

using (MagickImage image = new MagickImage("input.svg"))
{
    image.Scale(new Percentage(60));
    image.Write("output.png");
}

并通过添加imageMagick

dotnet add package Magick.NET.Core --version 8.3.3

error CS0246: The type or namespace name 'MagickImage' could not be found (are you missing a using directive or an assembly reference?

我该如何解决这个问题?我缺少什么导入/使用?
