Read file from sharepoint 2013 layouts folder

Question

I want to get the path of a file from _layouts folder in SharePoint 2013, for a stream input.

I tried:

iTextSharp.text.Document doc = new iTextSharp.text.Document(PageSize.A4); 
var path = Server.MapPath(@"\15\TEMPLATE\LAYOUTS\wfcourrierdep\images\LettreI.png");
var output = new FileStream(path, FileMode.Create);
var writer = PdfWriter.GetInstance(doc, output);
doc.Open();

And

iTextSharp.text.Document doc = new iTextSharp.text.Document(PageSize.A4);
var path = SPUtility.GetCurrentGenericSetupPath(@"TEMPLATE\LAYOUTS\wfcourrierdep\pdf\Dictionnaire.pdf");
var output = new FileStream(path, FileMode.Create);
var writer = PdfWriter.GetInstance(doc, output);
doc.Open();

No result

I want to use the GetCurrentGenericSetupPath or GetVersionedGenericSetupPath but I don't know what is the format of my URL I should pass in.

You can modify your code as below

 var path = SPUtility.GetCurrentGenericSetupPath(@"TEMPLATE\LAYOUTS\wfcourrierdep\pdf\Dictionnaire.pdf");
