Exemplos

O exemplo a seguir cria um FormattedText objeto e aplica vários estilos de formatação ao texto, incluindo SetForegroundBrush.

protected override void OnRender(DrawingContext drawingContext)
{
    string testString = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor";

    // Create the initial formatted text string.
    FormattedText formattedText = new FormattedText(
        testString,
        CultureInfo.GetCultureInfo("en-us"),
        FlowDirection.LeftToRight,
        new Typeface("Verdana"),
        32,
        Brushes.Black);

    // Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
    formattedText.MaxTextWidth = 300;
    formattedText.MaxTextHeight = 240;

    // Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
    // The font size is calculated in terms of points -- not as device-independent pixels.
    formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5);

    // Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
    formattedText.SetFontWeight(FontWeights.Bold, 6, 11);

    // Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
    formattedText.SetForegroundBrush(
                            new LinearGradientBrush(
                            Colors.Orange,
                            Colors.Teal,
                            90.0),
                            6, 11);

    // Use an Italic font style beginning at the 28th character and continuing for 28 characters.
    formattedText.SetFontStyle(FontStyles.Italic, 28, 28);

    // Draw the formatted text string to the DrawingContext of the control.
    drawingContext.DrawText(formattedText, new Point(10, 0));
}

Protected Overrides Sub OnRender(ByVal drawingContext As DrawingContext)
    Dim testString As String = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor"

    ' Create the initial formatted text string.
    Dim formattedText As New FormattedText(testString, CultureInfo.GetCultureInfo("en-us"), FlowDirection.LeftToRight, New Typeface("Verdana"), 32, Brushes.Black)

    ' Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
    formattedText.MaxTextWidth = 300
    formattedText.MaxTextHeight = 240

    ' Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
    ' The font size is calculated in terms of points -- not as device-independent pixels.
    formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5)

    ' Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
    formattedText.SetFontWeight(FontWeights.Bold, 6, 11)

    ' Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
    formattedText.SetForegroundBrush(New LinearGradientBrush(Colors.Orange, Colors.Teal, 90.0), 6, 11)

    ' Use an Italic font style beginning at the 28th character and continuing for 28 characters.
    formattedText.SetFontStyle(FontStyles.Italic, 28, 28)

    drawingContext.DrawText(formattedText, New Point(10, 0))
End Sub

 void SetForegroundBrush(System::Windows::Media::Brush ^ foregroundBrush);

public void SetForegroundBrush (System.Windows.Media.Brush foregroundBrush);

member this.SetForegroundBrush : System.Windows.Media.Brush -> unit

Public Sub SetForegroundBrush (foregroundBrush As Brush)

Parâmetros

foregroundBrush

Brush

O pincel a ser usado para o primeiro plano do texto.

Comentários

Esse método define o pincel de primeiro plano para toda a cadeia de caracteres de texto. Para definir o pincel de primeiro plano para um subconjunto da cadeia de caracteres de texto, use o SetForegroundBrush(Brush, Int32, Int32) método.
