Winnovative Html to pdf转换器页码不正确附加文件

Question

我有一个问题，使用Winnovative HTML到PDF转换器v8.0.0.0，我的pdf页码不正确。 这是我所做的。 我设置一个页脚在我的转换器

pdfConverter.PdfFooterOptions.AddTextArea(new TextArea(500, 0, 50, "&p;/&P;", new Font(new FontFamily("Arial"), 8))); 

然后我从一个URL创建一个文档

pdfDocument = pdfConverter.GetPdfDocumentObjectFromUrl(FirstUrl); 

然后我追加的文件从一个url

pdfDocument.AppendDocument(pdfConverter.GetPdfDocumentObjectFromUrl(SecondUrl)); 

所有页面从产生第一个url包含正确的页码，但附加文档中的页码似乎没有重新计算

例如： FirstUrl导致3页，第二页导致2页。 页码

1/5 
2/5 
3/5 
1/2 
2/2 

我想他们是这样的：

1/5 
2/5 
3/5 
4/5 
5/5 

我也尽量不喜欢这个转换后的页脚添加到转换器，但到pdfDocument：

PdfFont pdfFont = pdfDocument.Fonts.Add(new Font(new FontFamily("Arial"), 8)); 
    string strPageNum = "&p;/&P;"; 
    TextElement footerPageNumber = new TextElement(500, 0, 50, strPageNum, pdfFont); 
    pdfDocument.FooterTemplate.AddElement(footerPageNumber); 

但在这种情况下。只有来自第一个Url的页面才会获取页码，无法在附加文档的页面上看到。

感谢您的帮助。

Answer 1

遇到与另一个项目相同的问题。我终于找到了从许多Url创建PDF的正确方法。

我仍然设置页脚像这样的文件：

pdfConverter.PdfFooterOptions.AddTextArea(new TextArea(500, 0, 50, "&p;/&P;", new Font(new FontFamily("Arial"), 8))); 

然后我从一个URL创建一个文档，就像之前：

​​

代替，但附加其他PDF我得到的HtmlToPdfElement中的第二个url，如下所示：

HtmlToPdfElement pdfBody = new HtmlToPdfElement(secoundUrl); 

并最终将其添加到PDF文档，使用ew页面。

PdfPage newPage = pdfDocument.Pages.AddNewPage(); 
newPage.AddElement(pdfBody);

在PDF转换的最新版本Winovative HTML的，你现在可以添加页眉和页脚appeneded或前置到转换的结果外PDF文档。您可以在Add Header and Footer In External PDF Documents demo

与C＃源代码，一个完整的例子下面是相关代码从演示应用程序复制：

protected void convertToPdfButton_Click(object sender, EventArgs e) 
{ 
    // Create a HTML to PDF converter object with default settings 
    HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); 

    // Set the PDF file to be inserted before conversion result 
    string pdfFileBefore = Server.MapPath("~/DemoAppFiles/Input/PDF_Files/Merge_Before_Conversion.pdf"); 
    htmlToPdfConverter.PdfDocumentOptions.AddStartDocument(pdfFileBefore, addHeaderFooterInInsertedPdfCheckBox.Checked, 
         showHeaderInFirstPageCheckBox.Checked, showFooterInFirstPageCheckBox.Checked); 

    // Set the PDF file to be added after conversion result 
    string pdfFileAfter = Server.MapPath("~/DemoAppFiles/Input/PDF_Files/Merge_After_Conversion.pdf"); 
    htmlToPdfConverter.PdfDocumentOptions.AddEndDocument(pdfFileAfter, addHeaderFooterInAppendedPdfCheckBox.Checked, true, true); 

    // Enable header in the generated PDF document 
    htmlToPdfConverter.PdfDocumentOptions.ShowHeader = true; 

    // Draw header elements 
    if (htmlToPdfConverter.PdfDocumentOptions.ShowHeader) 
     DrawHeader(htmlToPdfConverter, true); 

    // Enable footer in the generated PDF document 
    htmlToPdfConverter.PdfDocumentOptions.ShowFooter = true; 

    // Draw footer elements 
    if (htmlToPdfConverter.PdfDocumentOptions.ShowFooter) 
     DrawFooter(htmlToPdfConverter, true, true); 

    string url = urlTextBox.Text; 

    // Convert the HTML page to a PDF document and add the external PDF documents 
    byte[] outPdfBuffer = htmlToPdfConverter.ConvertUrl(url); 

    // Send the PDF as response to browser 

    // Set response content type 
    Response.AddHeader("Content-Type", "application/pdf"); 

    // Instruct the browser to open the PDF file as an attachment or inline 
    Response.AddHeader("Content-Disposition", String.Format("attachment; filename=Header_Footer_in_External_PDF.pdf; size={0}", outPdfBuffer.Length.ToString())); 

    // Write the PDF document buffer to HTTP response 
    Response.BinaryWrite(outPdfBuffer); 

    // End the HTTP response and stop the current page processing 
    Response.End();
