使用例使用例

TextRenderingHint プロパティ、TextContrast プロパティ、および TextRenderingHint 列挙体の使用方法を示すコード例を次に示します。

この例は、Windows フォームでの使用を意図してデザインされています。コードをフォームに貼り付け、フォームの Paint イベントを処理するときに PaintEventArgs の e を渡して ChangeTextRenderingHintAndTextContrast メソッドを呼び出します。

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()
