Initializes a new instance of the TextDecoration class with the specified Location, Pen, PenOffset, PenOffsetUnit, and PenThicknessUnit values.

C#

public TextDecoration(System.Windows.TextDecorationLocation location, System.Windows.Media.Pen pen, double penOffset, System.Windows.TextDecorationUnit penOffsetUnit, System.Windows.TextDecorationUnit penThicknessUnit);

Parameters

location

TextDecorationLocation

The location of the text decoration.

pen

Pen

penOffset

Double

The vertical displacement from the text decoration's location. A negative value moves the decoration lower, while a positive value moves the decoration higher.

penOffsetUnit

TextDecorationUnit

The units used to interpret the value of penOffset.

penThicknessUnit

TextDecorationUnit

The units used to interpret the value of the Thickness for the pen.

Examples

The following code example shows how to create a TextDecoration by using the location, pen, penOffset, penOffsetUnit, and penThicknessUnit parameters.

C#

// Use a Maroon pen for the baseline text decoration.
private void SetMaroonBaseline()
{
    // Create an baseline text decoration 2 units lower than the default.
    TextDecoration myBaseline = new TextDecoration(
            TextDecorationLocation.Baseline,
            new Pen(Brushes.Maroon, 1),
            2.0,
            TextDecorationUnit.Pixel,
            TextDecorationUnit.Pixel);

    // Set the baseline decoration to a TextDecorationCollection and add it to the text block.
    TextDecorationCollection myCollection = new TextDecorationCollection();
    myCollection.Add(myBaseline);
    TextBlock2.TextDecorations = myCollection;
}

XAML

<TextBlock>
  <TextBlock.TextDecorations>
    <TextDecoration Location="Baseline" PenOffset="2" PenOffsetUnit="Pixel" PenThicknessUnit="Pixel" >
