PrintPreviewDialog.UseAntiAlias プロパティ

印刷においてオペレーティングシステムのアンチエイリアシング機能を使用するかどうかを示す値を取得または設定します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public Property UseAntiAlias As
 Boolean

Visual Basic (使用法)

Dim instance As PrintPreviewDialog
Dim value As Boolean

value = instance.UseAntiAlias

instance.UseAntiAlias = value

public bool UseAntiAlias { get;
 set; }

C++

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

/** @property */
public boolean get_UseAntiAlias ()

/** @property */
public void set_UseAntiAlias (boolean value)

JScript

public function get UseAntiAlias
 () : boolean

public function set UseAntiAlias
 (value : boolean)

プロパティ値
アンチエイリアシングを使用する場合は true。それ以外の場合は false。

解説

アンチエイリアシングを使用すると、フォントを描画するときにジャグラインが取り除かれます。

Document プロパティと UseAntiAlias プロパティを設定する PrintPreviewDialog のコード例を次に示します。この例では、TreeNode オブジェクトを含む TreeView1 という名前の TreeView がフォームに配置されていることを前提としています。各 TreeNode オブジェクトの Tag プロパティには、この例を実行するコンピュータからアクセスできるドキュメントの完全修飾名を設定する必要があります。各 TreeNode.Text プロパティには、TreeNode.Tag プロパティによって指定されたファイルを識別するための文字列を設定します。たとえば、TreeNode1.Tag を "c:\myDocuments\recipe.doc" に設定し、TreeNode1.Text を "recipe.doc" に設定します。この例では、PrintPreviewDialog1 という名前の PrintPreviewDialog と、Button1 という名前のボタンがフォームに配置されていることを前提としています。この例を実行するには、フォームのコンストラクタまたは Load のイベントハンドラで InitializePrintPreviewDialog メソッドを呼び出します。
