MVC 生成PDf表格并插入图片

2024-07-04 18:51:26   227人阅读

最近做的项目中有一个功能，将最终的个人信息生成PDF表格，并插入图片。对于没接触过的程序员来说回一片茫然，网上有多种生成PDf的方法，我给大家介绍一下我认为比较简单，好操作的一种。

iTextSharp组件

使用方法。

1，引入itextsharp.dll

2,  引入命名空间

            Directory.CreateDirectory(HttpContext.Current.Server.MapPath(filepath));<br>            PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath(filepath + model.ExamNo + ".pdf"), FileMode.Create));<br>       <br>　　　　    document.Open();<br>
            BaseFont bftitle = BaseFont.CreateFont(@"C:\\Windows\Fonts\SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            Font fonttitle = new Font(bftitle, 20, Font.UNDERLINE);
            BaseFont bf1 = BaseFont.CreateFont(@"C:\\Windows\Fonts\SIMSUN.TTC,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            Font font1 = new Font(bf1, 12);
            Font fonttitle10 = new Font(bf1, 12);
            Font fonttitle12 = new Font(bf1, 11);
            PdfPCell cellmode = new PdfPCell();<br><span style="color: rgb(255, 0, 0);">　　//因为显示照片部分显示5列，而后续部分显示四列，所以创建两个table</span>
          <span style="color: rgb(255, 0, 0);">  PdfPTable table = new PdfPTable(4);
            PdfPTable tablerow = new PdfPTable(5);
</span>

 不一步一步赘述了，将详细代码奉上。
