推荐答案

以下是将图像徽标添加到pdf中的代码。在应用程序设置中，你必须提到徽标的路径。





string HeaderImagePath = ConfigurationManager.AppSettings [PdfHeader]。ToString（ ）;

iTextSharp.text.Image headerLogo = iTextSharp.text.Image.GetInstance（HeaderImagePath）;



headerCell = new PdfPCell（headerLogo） ）;

headerCell.BorderWidth = 0;

headerCell.Horizo​​ntalAlignment = Element.ALIGN_CENTER;

headerCell.VerticalAlignment = Element.ALIGN_MIDDLE;

tblHeader.AddCell（headerCell）;

Here is the code for adding image logo into pdf. in app settings you have to mention the path of logo.


string HeaderImagePath = ConfigurationManager.AppSettings["PdfHeader"].ToString();
iTextSharp.text.Image headerLogo = iTextSharp.text.Image.GetInstance(HeaderImagePath);

headerCell = new PdfPCell(headerLogo);
headerCell.BorderWidth = 0;
headerCell.HorizontalAlignment = Element.ALIGN_CENTER;
headerCell.VerticalAlignment = Element.ALIGN_MIDDLE;
tblHeader.AddCell(headerCell);

最好使用iTextSharp.DLL，它将HTML页面转换成PDF格式。
