原标题:print wpf window to pdf file

I need to build a pdf file from an wpf window. that window contains a canvas with some draw and some textboxes and labels whith data.

一位朋友告诉我说,他用了结晶报告,但似乎不是我的好解决办法。

我想印刷一下信道上的形象,并写出一些电.盒和标签的 whi。

我需要一个不付报酬的解决办法。

我如何能够这样做?

问题回答

我通过称为iTextSharp的自由工具(EDIT)找到了解决这一问题的办法: iTextSharp是无商业用途的NOT,是假信息的 s。 实际上,我需要把世界森林论坛的固定文件转换为人民抵抗力量,因此,这与你想要做的工作略有不同,但或许也可以帮助你们。 基本上,这种做法是采用WPF固定文件(实际上是一种XPS格式),将其转换成图象。 之后,使用ITextSharp s PdfWriter语,将这一图像作为PDF文件的一个页子添加。 我尝试了其他几种方法,包括一种称为gxps的自由用途,但这种方法对我来说是最好的。

我的法典就是一个例子。

using iTextSharp.text;
using iTextSharp.text.pdf;
.
.
.
// create an iTextSharp document
Document doc = new Document(PageSize.LETTER, 0f, 0f, 0f, 0f);
PdfWriter.GetInstance(doc, new FileStream("C:\myFile.pdf", FileMode.Create));
doc.Open();

// cycle through each page of the WPF FixedDocument
DocumentPaginator paginator = myFixedDocument.DocumentPaginator;
for (int i = 0; i < paginator.PageCount; i++)
{
    // render the fixed document to a WPF Visual object
    Visual visual = paginator.GetPage(i).Visual;

    // create a temporary file for the bitmap image
    string targetFile = Path.GetTempFileName();

    // convert XPS file to an image
    using (FileStream outStream = new FileStream(targetFile, FileMode.Create))
    {
        PngBitmapEncoder enc = new PngBitmapEncoder();
        enc.Frames.Add(BitmapFrame.Create(CreateBitmapFromVisual(visual, 300, 300)));
        enc.Save(outStream);
    }

    // add the image to the iTextSharp PDF document
    using (FileStream fs = new FileStream(targetFile, FileMode.Open))
    {
        iTextSharp.text.Image png = iTextSharp.text.Image.GetInstance(System.Drawing.Image.FromStream(fs), System.Drawing.Imaging.ImageFormat.Png);
        png.ScalePercent(24f);
        doc.Add(png);
    }
}
doc.Close();

这里指的是如何在C#中建立固定文件:

using System.Windows.Documents;
using System.Windows.Documents.Serialization;
using System.Windows.Markup;

// create an instance of your XAML object (Window or UserControl)
var yourXAMLObj = new YourXAMLObject();

// create a FixedDocument and add a page of your XAML object
var fixedDocument = new FixedDocument();
fixedDocument.DocumentPaginator.PageSize = new Size(96 * 8.5, 96 * 11);

PageContent pageContent = new PageContent();
FixedPage fixedPage = new FixedPage();
fixedPage.Children.Add(yourXAMLObj);
fixedDocument.Pages.Add(pageContent);
((IAddChild)pageContent).AddChild(fixedPage);

我希望这一图书馆能帮助你。
