从资源文件中加载图片插入到word中：
Assembly assm = Assembly.GetExecutingAssembly();Stream istr = assm.GetManifestResourceStream("idgt_converter.Resources.caution.png");XWPFParagraph p = table.GetRow(rowIndex).GetCell(i).AddParagraph();XWPFRun r = p.CreateRun();var widthPx = Resource.caution.Width;var heightPx = Resource.caution.Height;var horzRezDpi = Resource.caution.HorizontalResolution;var vertRezDpi = Resource.caution.VerticalResolution;const int emusPerInch = 914400;var widthEmus = (int)(widthPx / horzRezDpi * emusPerInch);var heightEmus = (int)(heightPx / vertRezDpi * emusPerInch);XWPFPicture pic = r.AddPicture(istr, (int)PictureType.PNG, "caution.png", widthEmus, heightEmus);
AddPicture方法的宽和高要注意，不是图片的像素，而是需要根据像素和分辨率计算出来的值。
