NPOI导出Word插入图片问题解决方案

NPOI用版本2.2.0或者2.2.1时导出Word插入图片时，word文档打开报错

解决方案之一：用NPOI 2.1.3版本可以解决

            XWPFDocument doc = new XWPFDocument();

            XWPFParagraph p2 = doc.CreateParagraph();

            XWPFRun r2 = p2.CreateRun();

            r2.SetText("test");

            var img = Image.FromFile("D:\\11.png");

            var widthEmus = (int)(400.0 * 9525);

            var heightEmus = (int)(300.0 * 9525);

            using (FileStream picData = new FileStream("D:\\11.png", FileMode.Open, FileAccess.Read))

            {

                r2.AddPicture(picData, (int)PictureType.PNG, "11.png", widthEmus, heightEmus);

            }

            using (FileStream sw = File.Create("F:\\test.docx"))

            {

                doc.Write(sw);

            }
