在我的应用程序中,首先允许用户使用CKEDITOR创建html文档,用户可以在其中创建html文档并可以插入图像,表单字段等。生成的HTML文档将转换为PDF。 如果HTML文档包含纯文本而不是PDF文件成功创建但如果用户在其中插入图像而不是给出错误。 用于创建PDF文档的代码。
public ActionResult CreateFile(FormCollection data)
{
var filename = data["filename"];
var htmlContent = data["content"];
string sFilePath = Server.MapPath(_createdPDF + filename + ".html");
htmlContent = htmlContent.Trim();
if (!System.IO.File.Exists(sFilePath))
{
using (FileStream fs = new FileStream(sFilePath, FileMode.Create))
{
using (StreamWriter w = new StreamWriter(fs, Encoding.UTF8))
{
w.Write(htmlContent);
}
}
createPDF(sFilePath);
}
return View();
}
private MemoryStream createPDF(string sFilePath)
{
string filename = Path.GetFileNameWithoutExtension(sFilePath);
string name = Server.MapPath(_createdPDF + filename + ".pdf");
MemoryStream ms = new MemoryStream();
TextReader tr = new StringReader(sFilePath);
Document document = new Document(PageSize.A4, 30, 30, 30, 30);
string urldir = Request.Url.GetLeftPart(UriPartial.Path);
urldir = urldir.Substring(0, urldir.LastIndexOf("/") + 1);
Response.Write(urldir);
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(name, FileMode.Create));
document.Open();
string htmlText = "";
StreamReader sr;
sr = System.IO.File.OpenText(sFilePath);
htmlText = sr.ReadToEnd();
sr.Close();
WebClient wc = new WebClient();
Response.Write(htmlText);
var props = new Dictionary<string, Object>();
props["img_baseurl"] = @"C:\Documents and Settings\shubham\My Documents\visdatemplatemanger\visdatemplatemanger\";
List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(htmlText), null,props);
for (int k = 0; k < htmlarraylist.Count; k++)
{
document.Add((IElement)htmlarraylist[k]);
}
document.Close();
System.IO.File.Delete(sFilePath);
UploadURL(name);
return ms;
}
如果图像包含在HTML文档中,我得到的错误是:
Could not find a part of the path 'C:\Program Files\Common Files\Microsoft Shared\PDFimages\rectangle-shape.png'.
答案 0 :(得分:0)
iTextSharp将尝试解析基于HTTP的文档的相对图像,但是您需要提供的文件系统提供绝对路径或为其提供搜索基础。
//Image search base, path will be concatenated directly so make sure it contains a trailing slash
var props = new Dictionary<string, Object>();
props["img_baseurl"] = @"c:\images\";
//Include the props from above
htmlarraylist = HTMLWorker.ParseToList(sr, null, props);
