[转载]c#中使用ABCpdf处理PDF,so easy – 老赵【苏州】 – 博客园.
这几天项目中需要将页面导成PDF,刚开始使用iTextSharp,觉得在分页处理上比较复杂,后来无意中看到了ABCpdf,使用非常简单,并将一些常用操作记录下来,平时可以瞅瞅,也分享给大家伙们,废话不多说,直接贴代码。
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using WebSupergoo.ABCpdf9; using System.Text; namespace ABCpdfTest { /// <summary> /// 官方网站:http://www.websupergoo.com/ /// demo用的是当前的最新版本ABCpdf .NET 9.1 X64,支持当前windows的主流操作系统,包括最新的win8,IE10(服务器版本) /// ABCpdf有30天的试用期 /// 引用方式,安装ABCpdf组件,有两个DLL是有用的,需要对ABCpdf.dll添加引用,ABCpdf9-64.dll(引擎组件)放在bin目录下就可以了 /// 它有其他组件比如(iTextSharp)所不具备的功能,如能直接指定一个URL就可以将页面转换为PDF,这也是它的强大之处 /// 在选择版本时要注意,区分64位和32位,如果版本放错了,会发生错误,在IIS的部署上一定要注意,这里很可能会出现问题,请参考官方资料 /// 地址:http://www.websupergoo.com/support.htm 常见问题介绍的比较详细 /// </summary> public partial class Default : System.Web.UI.Page { string url = "http://www.websupergoo.com/support.htm"; private void DownloadPDF(string fileName, byte[] buffer) { Response.Buffer = false; Response.AddHeader("Connection", "Keep-Alive"); Response.ContentType = "application/octet-stream"; Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName); Response.AddHeader("Content-Length", buffer.Length.ToString()); Response.BinaryWrite(buffer); } private string GetFileName() { return DateTime.Now.ToString("yyyy-MM-dd-HH-mm-ss") + ".pdf"; } /// <summary> /// 指定URL生成PDF /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button1_Click(object sender, EventArgs e) { string fileName = GetFileName(); Doc doc = new Doc(); doc.Page = doc.AddPage();//新建一个页面 doc.Rect.Inset(10, 10);//设置矩形边距 int id = doc.AddImageUrl(url, true, 800, false);//添加一个URL的页面返回一个页面ID //以下这段代码很重要,关系到分页,如果不写这段代码,就无法分页 while (true) { //这个判断应该是判断id是否是页面对象,如果不是,就跳出循环 if (!doc.Chainable(id)) { break; } doc.Page = doc.AddPage(); id = doc.AddImageToChain(id);//这里是将这个可链接的对象ID添加到页面并返回一个id } doc.Flatten();//压缩pdf doc.Save(Server.MapPath(fileName));//这里保存pdf到相对路径 //你也你可以这样做把文件输出 byte[] buffer = doc.GetData();//得到bytes[] DownloadPDF(fileName, buffer); } /// <summary> /// 自定义页面 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button2_Click(object sender, EventArgs e) { string fileName = GetFileName(); Doc doc = new Doc(); doc.Page = doc.AddPage();//新建一个页面 doc.Rect.Inset(10, 10);//设置矩形边距,这里Rect是一个重要的对象,你也可以doc.Rect.String来设置属性 doc.FontSize = 24; //设置默认字体大小 doc.Color.String = "89,89,254"; int id = doc.AddText("Hello World!!!");//添加文字 doc.FrameRect(); //添加边框操作 doc.Save(Server.MapPath(fileName)); byte[] buffer = doc.GetData(); DownloadPDF(fileName, buffer); } /// <summary> /// 支持HTML元素 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button3_Click(object sender, EventArgs e) { string fileName = GetFileName(); Doc doc = new Doc(); doc.Page = doc.AddPage(); doc.Rect.Inset(10, 10); doc.AddHtml("<h2>How to use the ABCpdf</h2>"); doc.AddHtml("<hr>"); doc.AddHtml(@"<p>Use ABCpdf to create Adobe PDF documents on the fly.
