wiederholt AddImageUrl (url) zu assemblieren pdf-Dokument

Question

Ich benutze abcpdf und ich bin gespannt, ob wir rekursiv AddImageUrl() -Funktion aufrufen können, um PDF-Dokument zu kompilieren, die mehrere URLs kompilieren?

so etwas wie:

 int pageCount = 0; 
    int theId = theDoc.AddImageUrl("http://stackoverflow.com/search?q=abcpdf+footer+page+x+out+of+", true, 0, true); 
    //assemble document 
    while (theDoc.Chainable(theId)) 
    { 
     theDoc.Page = theDoc.AddPage(); 
     theId = theDoc.AddImageToChain(theId); 
    } 
    pageCount = theDoc.PageCount; 
    Console.WriteLine("1 document page count:" + pageCount); 
    //Flatten document 
    for (int i = 1; i <= pageCount; i++) 
    { 
     theDoc.PageNumber = i; 
     theDoc.Flatten(); 
    } 

    //now try again 
    theId = theDoc.AddImageUrl("http://stackoverflow.com/questions/1980890/pdf-report-generation", true, 0, true); 
    //assemble document 
    while (theDoc.Chainable(theId)) 
    { 
     theDoc.Page = theDoc.AddPage(); 
     theId = theDoc.AddImageToChain(theId); 
    } 
    Console.WriteLine("2 document page count:" + theDoc.PageCount); 
    //Flatten document 
    for (int i = pageCount + 1; i <= theDoc.PageCount; i++) 
    { 
     theDoc.PageNumber = i; 
     theDoc.Flatten(); 
    } 
    pageCount = theDoc.PageCount; 

edit: Code, basierend auf 'Jäger' Lösung scheint zu funktionieren:

 static void Main(string[] args) 
    { 
    Test2(); 
    } 

    static void Test2() 
    { 

    Doc theDoc = new Doc(); 
    // Set minimum number of items a page of HTML should contain. 
    theDoc.HtmlOptions.ContentCount = 10;// Otherwise the page will be assumed to be invalid. 
    theDoc.HtmlOptions.RetryCount = 10; // Try to obtain html page 10 times 
    theDoc.HtmlOptions.Timeout = 180000;// The page must be obtained in less then 10 seconds 

    theDoc.Rect.Inset(0, 10); // set up document 
    theDoc.Rect.Position(5, 15); 
    theDoc.Rect.Width = 602; 
    theDoc.Rect.Height = 767; 
    theDoc.HtmlOptions.PageCacheEnabled = false; 

    IList<string> urls = new List<string>(); 
    urls.Add("http://stackoverflow.com/search?q=abcpdf+footer+page+x+out+of+"); 
    urls.Add("http://stackoverflow.com/questions/1980890/pdf-report-generation"); 
    urls.Add("http://yahoo.com"); 
    urls.Add("http://stackoverflow.com/questions/4338364/recursively-call-addimageurlurl-to-assemble-pdf-document"); 

    foreach (string url in urls) 
     AddImage(ref theDoc, url); 

    //Flatten document 
    for (int i = 1; i <= theDoc.PageCount; i++) 
    { 
     theDoc.PageNumber = i; 
     theDoc.Flatten(); 
    } 

    theDoc.Save("batchReport.pdf"); 
    theDoc.Clear(); 
    Console.Read(); 

    } 


    static void AddImage(ref Doc theDoc, string url) 
    { 
    int theId = theDoc.AddImageUrl(url, true, 0, true); 
    while (theDoc.Chainable(theId)) 
    { 
     theDoc.Page = theDoc.AddPage(); 
     theId = theDoc.AddImageToChain(theId); // is this right? 
    } 
    Console.WriteLine(string.Format("document page count: {0}", theDoc.PageCount.ToString())); 
    } 

bearbeiten 2: leider Aufruf AddImageUrl mehrere Male, wenn PDF-Dokumente zu erzeugen doesn‘ t scheint zu arbeiten ...

Endlich zuverlässige Lösung gefunden. Anstatt die Funktion AddImageUrl() für dasselbe zugrunde liegende Dokument auszuführen, sollten wir die Funktion AddImageUrl() auf ihrem eigenen Doc-Dokument ausführen und eine Sammlung von Dokumenten erstellen, die wir am Ende mit der Append() -Methode zu einem Dokument zusammensetzen. Hier ist der Code:

 static void Main(string[] args) 
    { 
    Test2(); 
    } 

    static void Test2() 
    { 
    Doc theDoc = new Doc(); 
    var urls = new Dictionary<int, string>(); 
    urls.Add(1, "http://www.asp101.com/samples/server_execute_aspx.asp"); 
    urls.Add(2, "http://stackoverflow.com/questions/4338364/repeatedly-call-addimageurlurl-to-assemble-pdf-document"); 
    urls.Add(3, "http://www.google.ca/"); 
    urls.Add(4, "http://ca.yahoo.com/?p=us"); 
    var theDocs = new List<Doc>(); 

    foreach (int key in urls.Keys) 
     theDocs.Add(GetReport(urls[key])); 

    foreach (var doc in theDocs) 
    { 
     if (theDocs.IndexOf(doc) == 0) 
      theDoc = doc; 
     else 
      theDoc.Append(doc); 
    } 

    theDoc.Save("batchReport.pdf"); 
    theDoc.Clear(); 
    Console.Read(); 

    } 


    static Doc GetReport(string url) 
    { 

    Doc theDoc = new Doc(); 
    // Set minimum number of items a page of HTML should contain. 
    theDoc.HtmlOptions.ContentCount = 10;// Otherwise the page will be assumed to be invalid. 
    theDoc.HtmlOptions.RetryCount = 10; // Try to obtain html page 10 times 
    theDoc.HtmlOptions.Timeout = 180000;// The page must be obtained in less then 10 seconds 

    theDoc.Rect.Inset(0, 10); // set up document 
    theDoc.Rect.Position(5, 15); 
    theDoc.Rect.Width = 602; 
    theDoc.Rect.Height = 767; 
    theDoc.HtmlOptions.PageCacheEnabled = false; 

    int theId = theDoc.AddImageUrl(url, true, 0, true); 
    while (theDoc.Chainable(theId)) 
    { 
     theDoc.Page = theDoc.AddPage(); 
     theId = theDoc.AddImageToChain(theId); 
    } 

    //Flatten document 
    for (int i = 1; i <= theDoc.PageCount; i++) 
    { 
     theDoc.PageNumber = i; 
     theDoc.Flatten(); 
    } 

    return theDoc; 
    } 

    }
