使用pdfsharp保存wpf布局为pdf，c＃

问题描述

我是c＃，wpf和pdfsharp库的新手。
这是我的XAML代码：

 < Grid> 
< zoom：ZoomControl> 
< graphsharp：GraphLayout x：Name =graphLayout
 Graph ={Binding ElementName = root，Path = GraphToVisualize}
 LayoutAlgorithmType =FR
 OverlapRemovalAlgorithmType = FSA
 HighlightAlgorithmType =简单>< / graphsharp：GraphLayout> 
< / zoom：ZoomControl> 
< Button Content =ButtonHeight =23Name =button1Width =75Margin =12,294,658,412Click =button1_Click/> 
< / Grid> 
  

我现在要使用Pdfsharp将我的graphLayout保存为pdf文件。我创建了一个按钮，并基本上使用pdfsharp wiki中的hello world示例代码来启动。

  PdfDocument document = new PdfDocument（）; 
 document.Info.Title =Created with PDFsharp; 
 PdfPage page = document.AddPage（）; 
 XGraphics gfx = XGraphics.FromPdfPage（page）; 
 XFont font = new XFont（Verdana，20，XFontStyle.BoldItalic）; 
 gfx.DrawString（My Graph，font，XBrushes.Black，
 new XRect（0，0，page.Width，page.Height），
 XStringFormats.TopCenter）; 
 const string filename =MyGraph.pdf; 
 document.Save（graphLayout + filename）; 
 Process.Start（filename）; 
  

我得到一个pdf，但里面只有文字。有人可以告诉我，我怎么可以将整个布局保存为pdf？
thanks

解决方案

阅读文档：

我不是知道你可以直接从WPF转换为PDF，但它很简单

带有WPF< - > XPS< - > PDF。 b

  MemoryStream lMemoryStream = new MemoryStream（）; 
 Package package = Package.Open（lMemoryStream，FileMode.Create）; 
 XpsDocument doc = new XpsDocument（package）; 
 XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter（doc）; 
 writer.Write（dp）; 
 doc.Close（）; 
 package.Close（）; 
 
 var pdfXpsDoc = PdfSharp.Xps.XpsModel.XpsDocument.Open（lMemoryStream）; 
 PdfSharp.Xps.XpsConverter.Convert（pdfXpsDoc，d.FileName，0）; 
  

其中dp是您的Visual / layout

I'm new to c#, wpf and the pdfsharp library.This is my XAML Code:

<Grid>
    <zoom:ZoomControl>
    <graphsharp:GraphLayout x:Name="graphLayout"
                            Graph="{Binding ElementName=root, Path=GraphToVisualize}"
                            LayoutAlgorithmType="FR"
                            OverlapRemovalAlgorithmType="FSA"
                            HighlightAlgorithmType="Simple"></graphsharp:GraphLayout>
    </zoom:ZoomControl>
    <Button Content="Button" Height="23" Name="button1" Width="75" Margin="12,294,658,412" Click="button1_Click" />
</Grid>

I want now save my "graphLayout" to a pdf-file using Pdfsharp. I created a button and used basically the "hello world" sample code in the pdfsharp wiki to start.

PdfDocument document = new PdfDocument();
        document.Info.Title = "Created with PDFsharp";
        PdfPage page = document.AddPage();
        XGraphics gfx = XGraphics.FromPdfPage(page);
        XFont font = new XFont("Verdana", 20, XFontStyle.BoldItalic);
        gfx.DrawString("My Graph", font, XBrushes.Black,
            new XRect(0, 0, page.Width, page.Height),
            XStringFormats.TopCenter);
        const string filename = "MyGraph.pdf";
        document.Save(graphLayout+filename);
        Process.Start(filename);

I get a pdf , but there is just the text in it. Can somebody tell me please, how i can save the whole layout into a pdf?thanks

Read documentations: http://www.pdfsharp.net/wiki/Graphics.ashx?AspxAutoDetectCookieSupport=1

I am not aware that you can convert directly from WPF to PDF, however it's pretty simple

with WPF<-->XPS<-->PDF.

MemoryStream lMemoryStream = new MemoryStream();
Package package = Package.Open(lMemoryStream, FileMode.Create);
XpsDocument doc = new XpsDocument(package);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(doc);
writer.Write(dp);
doc.Close();
package.Close();

var pdfXpsDoc = PdfSharp.Xps.XpsModel.XpsDocument.Open(lMemoryStream);
PdfSharp.Xps.XpsConverter.Convert(pdfXpsDoc, d.FileName, 0);

where dp is your Visual/layout
