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

Problem

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
