如何将该图像保存为高清图像？

Question

我正在尝试修改歌曲的元数据。 我可以使用它，但是如果用户未指定专辑封面图像，我会自动从保存该专辑图像的图片框中绘制一个。 返回的图像真的很模糊-有什么办法可以使它尽可能的高清晰度吗？ 这是我处理代码的部分：

 if (isDir == false){
            IPicture art2 = new TagLib.Picture(new TagLib.ByteVector((byte[])new System.Drawing.ImageConverter().ConvertTo(pictureBox1.Image, typeof(byte[])))); //I make the new picture here.

            TagLib.File file2 = TagLib.File.Create(Properties.Settings.Default.NowPlayingPath);
            file2.Tag.Title = SongBox.Text;
            file2.Tag.AlbumArtists = artist;
            file2.Tag.Genres = genre;
            file2.Tag.Year = Convert.ToUInt32(YearBox.Text);
            file2.Tag.Composers = composers;
            file2.Tag.Pictures = new IPicture[1] { art2 };//I set the picture here.
            file2.Save();
            MessageBox.Show("You'll need to reload your song to continue listening to it.", "Settings saved.");
            this.Hide();
        }
    }

尝试使用MemoryStream获取图像作为字节数组：

MemoryStream ms = new MemoryStream();
pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] buff = ms.GetBuffer();
IPicture art2 = new TagLib.Picture(new TagLib.ByteVector(buff));
