在ITextSharp免费许可证下动态创建.pdfs

本文关键字：动态 创建 pdfs 许可证 ITextSharp 免费 | 更新日期: 2023-09-27 18:26:56

在ASP.NET C#网站/服务器中，我使用名为ITextSharp的.pdf creater库来创建带有文本&一些关于产品的图片。

和往常一样，老板不想买执照。我知道，如果我使用ITextSharp 4.1.6或更低版本，我可以在免费许可证下使用该库（不是吗？）

我的问题：旧版本（4.1.6-）/免费版本是否满足我生成顶部有图像、中间有文本内容（某些段落）、底部有图像的pdf的需求？我会发现一些API函数对我自己不可用，因为我有旧版本吗？

你会建议我使用另一个开源的ASP.NET C#.pdf生成器吗？

是的，您可以这样做，旧版本也可以。我已经附上了使用字符串生成器生成带有itext Sharp的html的代码。

Document doc = new Document(PageSize.LETTER, 10, 10, 42, 35);
                iTextSharp.text.pdf.PdfWriter wri = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, new FileStream("D:''PurchaseOrderDetails.pdf", FileMode.Create));
                doc.Open();//
                StringBuilder builder = new StringBuilder();
                builder.Append("<html>");
                builder.Append("<head>");
                builder.Append("</head>");
                builder.Append("<body>");
                builder.Append("<img src='"D:''Images''logo_left.png'" align='"right'"/>");
                builder.Append("<br/><br/><br/><br>");
                builder.Append("");
                builder.Append("<h1 style='"font-weight: bold'">Purchase Order Details</h1> ");
                builder.Append("");
