PreviewPrintController

---

System.Drawing.Printing (system.drawing.dll)

class

This class, derived from PrintController , manages the printing of a document to a series of Image objects, which can then be displayed to the user as a preview of the final printed output.

You would typically use a System.Windows.Forms.PrintPreviewDialog or System.Windows.Forms.PrintPreviewControl , which then uses this class in its implementation to display a series of page images to the user.

You can enable antialiasing to improve display quality, with the UseAntiAlias property. GetPreviewPageInfo() returns an array of PreviewPageInfo objects, which encapsulate the images representing each page to be printed.

To use a PreviewPrintController independently of the aforementioned controls, you can construct an instance and assign it to the PrintDocument.PrintController . If you then call PrintDocument.Print() , the controller will be populated with the images, which you can then retrieve with the GetPreviewPageInfo() method.

 public class  PreviewPrintController  : PrintController {  // Public Constructors  public  PreviewPrintController  ();  // Public Instance Properties  public virtual bool  UseAntiAlias  {set; get; }  // Public Instance Methods  public PreviewPageInfo[ ]  GetPreviewPageInfo  ();    public override void  OnEndPage  (PrintDocument  document  , PrintPageEventArgs  e  );  // overrides PrintController  public override void  OnEndPrint  (PrintDocument  document  , PrintEventArgs  e  );  // overrides PrintController  public override Graphics  OnStartPage  (PrintDocument  document  , PrintPageEventArgs  e  );  // overrides PrintController  public override void  OnStartPrint  (PrintDocument  document  , PrintEventArgs  e  );  // overrides PrintController  }
