PrintPreviewControl::UseAntiAlias Property

Gets or sets a value indicating whether printing uses the anti-aliasing features of the operating system.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
property bool UseAntiAlias {
	bool get ();
	void set (bool value);
}

Property Value

Type: System::Boolean
true if anti-aliasing is used; otherwise, false.

Anti-aliasing removes jagged lines when fonts are rendered.

The following code example demonstrates the Document, UseAntiAlias, and Zoom properties of the PrintPreviewControl. To run this example, place the following code in a form and call the InitializePrintPreviewControl method from the form’s constructor or Load event-handling method.

internal:
   // Declare the PrintPreviewControl object and the  
   // PrintDocument object.
   PrintPreviewControl^ PrintPreviewControl1;

private:
   System::Drawing::Printing::PrintDocument^ docToPrint;
   void InitializePrintPreviewControl()
   {
      // Construct the PrintPreviewControl. 
      this->PrintPreviewControl1 = gcnew PrintPreviewControl;

      // Set location, name, and dock style for PrintPreviewControl1. 
      this->PrintPreviewControl1->Location = Point(88,80);
      this->PrintPreviewControl1->Name = "PrintPreviewControl1";
      this->PrintPreviewControl1->Dock = DockStyle::Fill;

      // Set the Document property to the PrintDocument  
      // for which the PrintPage event has been handled. 
      this->PrintPreviewControl1->Document = docToPrint;

      // Set the zoom to 25 percent. 
      this->PrintPreviewControl1->Zoom = 0.25;

      // Set the document name. This will show be displayed when  
      // the document is loading into the control. 
      this->PrintPreviewControl1->Document->DocumentName = "c:\\someFile";

      // Set the UseAntiAlias property to true so fonts are smoothed 
      // by the operating system. 
      this->PrintPreviewControl1->UseAntiAlias = true;

      // Add the control to the form. 
      this->Controls->Add( this->PrintPreviewControl1 );

      // Associate the event-handling method with the 
      // document's PrintPage event. 
      this->docToPrint->PrintPage += gcnew System::Drawing::Printing::PrintPageEventHandler( this, &Form1::docToPrint_PrintPage );
   }

   // The PrintPreviewControl will display the document 
   // by handling the documents PrintPage event 
   void docToPrint_PrintPage( Object^ /*sender*/, System::Drawing::Printing::PrintPageEventArgs^ e )
   {
      // Insert code to render the page here. 
      // This code will be called when the control is drawn. 
      // The following code will render a simple 
      // message on the document in the control.
      String^ text = "In docToPrint_PrintPage method.";
      System::Drawing::Font^ printFont = gcnew System::Drawing::Font( "Arial",35,FontStyle::Regular );
      e->Graphics->DrawString( text, printFont, Brushes::Black, 10, 10 );
   }
PrintPreviewControl class.


To run this example place the following code in a form 
and call the InitializePrintPreviewControl method from the form’s 
constructor or Load method.
