PrintPreviewDialog.UseAntiAlias 屬性

定義

取得或設定值,指出列印時是否使用作業系統的反鋸齒補償功能。

public:
 property bool UseAntiAlias { bool get(); void set(bool value); };
public bool UseAntiAlias { get; set; }
member this.UseAntiAlias : bool with get, set
Public Property UseAntiAlias As Boolean

屬性值

如果使用反鋸齒補償,則為 true,否則為 false

備註

反鋸齒會在轉譯字型時移除不規則的行。

下列程式碼範例示範 PrintPreviewDialogUseAntiAlias 屬性的 Document 設定。 此範例假設表單包含 TreeView 包含 物件的具名 TreeView1TreeNodeTag每個 TreeNode 物件的 屬性都必須設定為完整檔案名稱,該名稱可由執行此範例的電腦存取。 將每個 TreeNode.Text 屬性設定為可識別 屬性所指定檔案的 TreeNode.Tag 字串。 例如,您可以將 設定為 「c:\myDocuments\recipe.doc」,並將 TreeNode1.Text 設定 TreeNode1.Tag 為 「recipe.doc」。 此範例也假設表單包含 PrintPreviewDialog 名為 PrintPreviewDialog1 的 ,以及名為 的 Button1 按鈕。 若要執行此範例,請在表單的建構函式或 Load 事件處理常式中呼叫 InitializePrintPreviewDialog 方法。
