定义

命名空间:

System.Windows.Media

程序集:

PresentationCore.dll

初始化 TextEffect 类的新实例。

重载

TextEffect()	初始化 TextEffect 类的新实例。
TextEffect(Transform, Brush, Geometry, Int32, Int32)	通过指定类属性值来初始化 TextEffect 类的新实例。

TextEffect()

初始化 TextEffect 类的新实例。

public:
 TextEffect();

public TextEffect ();

Public Sub New ()

示例

下面的代码示例演示如何创建、 TextEffect设置其属性并将其添加到 TextEffectCollection 指定文本对象。

// Create and configure a simple color animation sequence.  Timespan is in 1000ns ticks.
ColorAnimation colorAnimation =
    new ColorAnimation(Colors.Maroon, Colors.White, new Duration(new TimeSpan(1000000)));
colorAnimation.AutoReverse = true;
colorAnimation.RepeatBehavior = RepeatBehavior.Forever;

// Create a new brush and apply the color animation.
SolidColorBrush solidColorBrush = new SolidColorBrush(Colors.Black);
solidColorBrush.BeginAnimation(SolidColorBrush.ColorProperty, colorAnimation);

// Create a new TextEffect object. Set the foreground to the color-animated brush.
TextEffect textEffect = new TextEffect();
textEffect.Foreground = solidColorBrush;

// Apply the TextEffect to the entire range of characters.
textEffect.PositionStart = 0;
textEffect.PositionCount = int.MaxValue;

// Create a new text Run, and add the TextEffect to the TextEffectCollection of the Run.
Run flickerRun = new Run("Text that flickers...");
flickerRun.TextEffects = new TextEffectCollection();
flickerRun.TextEffects.Add(textEffect);

MyFlowDocument.Blocks.Add(new Paragraph(flickerRun));

' Create and configure a simple color animation sequence.  Timespan is in 1000ns ticks.
Dim colorAnimation As New ColorAnimation(Colors.Maroon, Colors.White, New Duration(New TimeSpan(1000000)))
colorAnimation.AutoReverse = True
colorAnimation.RepeatBehavior = RepeatBehavior.Forever

' Create a new brush and apply the color animation.
Dim solidColorBrush As New SolidColorBrush(Colors.Black)
solidColorBrush.BeginAnimation(SolidColorBrush.ColorProperty, colorAnimation)

' Create a new TextEffect object. Set the foreground to the color-animated brush.
Dim textEffect As New TextEffect()
textEffect.Foreground = solidColorBrush

' Apply the TextEffect to the entire range of characters.
textEffect.PositionStart = 0
textEffect.PositionCount = Integer.MaxValue

' Create a new text Run, and add the TextEffect to the TextEffectCollection of the Run.
Dim flickerRun As New Run("Text that flickers...")
flickerRun.TextEffects = New TextEffectCollection()
flickerRun.TextEffects.Add(textEffect)

MyFlowDocument.Blocks.Add(New Paragraph(flickerRun))

TextEffect(Transform, Brush, Geometry, Int32, Int32)

通过指定类属性值来初始化 TextEffect 类的新实例。

public:
 TextEffect(System::Windows::Media::Transform ^ transform, System::Windows::Media::Brush ^ foreground, System::Windows::Media::Geometry ^ clip, int positionStart, int positionCount);

public TextEffect (System.Windows.Media.Transform transform, System.Windows.Media.Brush foreground, System.Windows.Media.Geometry clip, int positionStart, int positionCount);

new System.Windows.Media.TextEffect : System.Windows.Media.Transform * System.Windows.Media.Brush * System.Windows.Media.Geometry * int * int -> System.Windows.Media.TextEffect

Public Sub New (transform As Transform, foreground As Brush, clip As Geometry, positionStart As Integer, positionCount As Integer)

参数

transform

Transform

应用于 Transform 的 TextEffect。

foreground

Brush

要应用于 Brush 的内容的 TextEffect。

clip

Geometry

TextEffect 的剪辑区域。

positionStart

Int32

在文本中应用 TextEffect 的开始位置。

positionCount

Int32

在文本中应用 TextEffect 的位置数。

示例

下面的代码示例演示如何调用 TextEffect 构造函数。 请注意，在这种情况下，transform将设置null参数和clip参数，因为不需要这些参数值。

// Create a new TextEffect object, setting only the foreground brush, position start, and position count.
TextEffect textEffect = new TextEffect(null, solidColorBrush, null, 0, int.MaxValue);

' Create a new TextEffect object, setting only the foreground brush, position start, and position count.
Dim textEffect As New TextEffect(Nothing, solidColorBrush, Nothing, 0, Integer.MaxValue)
