Ejemplos

En el ejemplo siguiente se crea un FormattedText objeto y, a continuación, se aplican varios estilos de formato al texto, incluido 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)

    ' Draw the formatted text string to the DrawingContext of the control.
    drawingContext.DrawText(formattedText, New Point(10, 0))
End Sub

Este método establece el pincel de primer plano para toda la cadena de texto. Para establecer el pincel de primer plano para un subconjunto de la cadena de texto, use el SetForegroundBrush(Brush, Int32, Int32) método .
