Graphics.TextRenderingHint-Eigenschaft

Ruft den Wiedergabemodus für Text ab, der diesem Graphics zugeordnet ist, oder legt diesen fest.

Namespace: System.Drawing
Assembly: System.Drawing (in system.drawing.dll)

Syntax

'Declaration
Public Property TextRenderingHint As TextRenderingHint
'Usage
Dim instance As Graphics
Dim value As TextRenderingHint

value = instance.TextRenderingHint

instance.TextRenderingHint = value

public TextRenderingHint TextRenderingHint { get; set; }

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

/** @property */
public TextRenderingHint get_TextRenderingHint ()

/** @property */
public void set_TextRenderingHint (TextRenderingHint value)

public function get TextRenderingHint () : TextRenderingHint

public function set TextRenderingHint (value : TextRenderingHint)

Eigenschaftenwert

Einer der TextRenderingHint-Werte.

Hinweise

Das Textwiedergabehinting gibt an, ob Text mit Antialiasing wiedergegeben wird.

Beispiel

Im folgenden Codebeispiel wird die Verwendung der TextRenderingHint-Eigenschaft und der TextContrast-Eigenschaft veranschaulicht.

Dieses Beispiel ist für die Verwendung mit Windows Forms vorgesehen. Fügen Sie den Code in ein Formular ein, und rufen Sie beim Behandeln des Paint-Ereignisses des Formulars die ChangeTextRenderingHintAndTextContrast-Methode auf, wobei Sie e als PaintEventArgs übergeben.

Private Sub ChangeTextRenderingHintAndTextContrast(ByVal e As _
    PaintEventArgs)

    ' Retrieve the graphics object.
    Dim formGraphics As Graphics = e.Graphics

    ' Declare a new font.
    Dim myFont As Font = New Font(FontFamily.GenericSansSerif, _
        20, FontStyle.Regular)

    ' Set the TextRenderingHint property.
    formGraphics.TextRenderingHint = _
        System.Drawing.Text.TextRenderingHint.SingleBitPerPixel

    ' Draw the string.
    formGraphics.DrawString("Hello World", myFont, _
        Brushes.Firebrick, 20.0F, 20.0F)

    ' Change the TextRenderingHint property.
    formGraphics.TextRenderingHint = _
        System.Drawing.Text.TextRenderingHint.AntiAliasGridFit

    ' Draw the string again.
    formGraphics.DrawString("Hello World", myFont, _
        Brushes.Firebrick, 20.0F, 60.0F)

    ' Set the text contrast to a high-contrast setting.
    formGraphics.TextContrast = 0

    ' Draw the string.
    formGraphics.DrawString("Hello World", myFont, _
        Brushes.DodgerBlue, 20.0F, 100.0F)

    ' Set the text contrast to a low-contrast setting.
    formGraphics.TextContrast = 12

    ' Draw the string again.
    formGraphics.DrawString("Hello World", myFont, _
        Brushes.DodgerBlue, 20.0F, 140.0F)

    ' Dispose of the font object.
    myFont.Dispose()

End Sub
