Magick.NET跨平台压缩图片的用法

//首先NuGet安装：Magick.NET.Core，Magick.NET-Q16-AnyCPU<br>using ImageMagick;
 
/// <summary>
        /// 压缩图片
        /// </summary>
        /// <param name="imageData">图片字节流</param>
        /// <param name="maxWidth">最大宽度</param>
        /// <param name="maxHeight">最大高度</param>
        /// <returns></returns>
        public static byte[] CompressImage(byte[] imageData, int maxWidth, int maxHeight)
        {
            using var image = new MagickImage(imageData);
            double width = image.Width;
            double height = image.Height;
 
            double scale = Math.Min(maxWidth / width, maxHeight / height);
 
            if (scale >= 1) //图片尺寸不高于最大尺寸，直接返回原图  
                return imageData;
 
            int newWidth = (int)Math.Round(width * scale, MidpointRounding.AwayFromZero);
            int newHeight = (int)Math.Round(height * scale, MidpointRounding.AwayFromZero);
 
            image.Resize(newWidth, newHeight);
 
            var compressedImage = image.ToByteArray(MagickFormat.Jpg);
 
            return compressedImage;
        }
