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

public bool UseAntiAlias { get; set; }

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.

// Declare the PrintPreviewControl object and the 
// PrintDocument object.
internal PrintPreviewControl PrintPreviewControl1;
private System.Drawing.Printing.PrintDocument docToPrint = 
	new System.Drawing.Printing.PrintDocument();

private void InitializePrintPreviewControl()

	// Construct the PrintPreviewControl.
	this.PrintPreviewControl1 = new PrintPreviewControl();

	// Set location, name, and dock style for PrintPreviewControl1.
	this.PrintPreviewControl1.Location = new 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.

	// Associate the event-handling method with the
	// document's PrintPage event.
	this.docToPrint.PrintPage += 
		new System.Drawing.Printing.PrintPageEventHandler(

// The PrintPreviewControl will display the document
// by handling the documents PrintPage event
private 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 = 
		new Font("Arial", 35, FontStyle.Regular);

	e.Graphics.DrawString(text, printFont,
		Brushes.Black, 10, 10);
