PDFFormat Class
Members  Example 

ArcGIS.Desktop.Mapping Namespace : PDFFormat Class
Represents a Portable Document Format (PDF) object that can be used to export a MapView, MapFrame, or a Layout.
Syntax
public class PDFFormat : ExportFormat 
Public Class PDFFormat 
   Inherits ExportFormat
Remarks
PDF files are designed to be consistently viewable and printable across different platforms. They are commonly used for distributing documents on the Web and are becoming a standard interchange format for content delivery. PDFs are editable in many graphics applications and can retain annotation, labeling, and attribute data for map layers. PDF exports from support embedding of fonts and thus can display symbology correctly even if the user does not have Esri fonts installed.
Example
The following examples demonstrate how to export a Layout, a MapFrame, and a MapView to PDF format.
//This example demonstrates how to export a layout to PDF.
