fo-dicom 怎么将图片png合成打包为dcm打印文件

fo-dicom 如何实现将图片png,bmp,jpg合成打包为dicom打印的.dcm文件

之前做得过一个需求 就是通过dicom协议向打印机推送打印，但是打印程序是公司元老遗留的项目 已经没有了源码,

操作打印需要使用dcm文件进行提交 但我这边只有png图片并没有现成的dcm,出于考虑打印软件兼容性问题又不能换打印程序 就需要将png图像合成打包为dicom文件 再进行打印

以下是实现打包的代码：

    /// <summary>
    /// Dicom文件创建器
    /// </summary>
    public class DicomFileBuilder
    {
        private string _ImgFile;

        /// <summary>
        /// 实例化函数
        /// </summary>
        /// <param name="ImgFile">图片文件地址</param>
        public DicomFileBuilder(string ImgFile)
        {
            _ImgFile = ImgFile;
        }

        private byte[] GetPixels(Bitmap pngBitmap)
        {
            byte[] bytes = new byte[pngBitmap.Width * pngBitmap.Height * 3];
            int wide = pngBitmap.Width;
            int i = 0;
            int height = pngBitmap.Height;
            for (int y = 0; y < height; y++)
            {
                for (int x = 0; x < wide; x++)
                {
                    var srcColor = pngBitmap.GetPixel(x, y);
                    //bytes[i] = (byte)(srcColor.R * .299 + srcColor.G * .587 + srcColor.B * .114);
                    bytes[i] = srcColor.R;
                    i++;
                    bytes[i] = srcColor.G;
                    i++;
                    bytes[i] = srcColor.B;
                    i++;
                }
            }
            return bytes;
        }

        /// <summary>
        /// 获取dcm文件流
        /// </summary>
        /// <returns></returns>
        public Stream Get()
        {
            Stream DcmStream = new MemoryStream();
            using (FileStream PngStream = new FileStream(_ImgFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
            {
                using (Bitmap PngBitmap = new Bitmap(PngStream))
                {
                    //读取图像流
                    byte[] PngPixels = this.GetPixels(PngBitmap);
                    MemoryByteBuffer buffer = new MemoryByteBuffer(PngPixels);

                    DicomDataset PrintDataset = new DicomDataset();
