UIElement.BitmapEffect UIElement.BitmapEffect UIElement.BitmapEffect UIElement.BitmapEffect Property

定義

警告

此 API 現已淘汰。

取得或設定直接套用至此元素呈現內容的點陣圖效果。Gets or sets a bitmap effect that applies directly to the rendered content for this element. 這是相依性屬性。This is a dependency property.

public:
 property System::Windows::Media::Effects::BitmapEffect ^ BitmapEffect { System::Windows::Media::Effects::BitmapEffect ^ get(); void set(System::Windows::Media::Effects::BitmapEffect ^ value); };
[System.Obsolete("BitmapEffects are deprecated and no longer function.  Consider using Effects where appropriate instead.")]
[System.Obsolete("Avoid using BitmapEffects as they have very poor performance characteristics.  They will be deprecated in a future version.  Consider using the UIElement.Effect property and ShaderEffects where appropriate instead.")]
public System.Windows.Media.Effects.BitmapEffect BitmapEffect { get; set; }
member this.BitmapEffect : System.Windows.Media.Effects.BitmapEffect with get, set
Public Property BitmapEffect As BitmapEffect

屬性值

要套用的點陣圖效果。The bitmap effect to apply.

範例

下列範例會設定點陣圖效果,使用BlurBitmapEffectThe following example sets a bitmap effect, using BlurBitmapEffect.

// Get a reference to the Button.
Button myButton = (Button)sender;

// Initialize a new BlurBitmapEffect that will be applied
// to the Button.
BlurBitmapEffect myBlurEffect = new BlurBitmapEffect();

// Set the Radius property of the blur. This determines how 
// blurry the effect will be. The larger the radius, the more
// blurring. 
myBlurEffect.Radius = 10;

// Set the KernelType property of the blur. A KernalType of "Box"
// creates less blur than the Gaussian kernal type.
myBlurEffect.KernelType = KernelType.Box;

// Apply the bitmap effect to the Button.
myButton.BitmapEffect = myBlurEffect;

備註

BitmapEffect 是抽象類型,因此XAMLXAML使用方式必須實作的衍生的類別的BitmapEffect,例如OuterGlowBitmapEffectBitmapEffect is an abstract type, therefore the XAMLXAML usage requires an implemented derived class of BitmapEffect, such as OuterGlowBitmapEffect. 實作一個衍生類別的附註是集合型別,可讓您指定多個循序BitmapEffect,使用巢狀的標記語法。Note that one implemented derived class is a collection type that allows you to specify more than one sequential BitmapEffect, using a nested tag syntax.

目前沒有衍生的類別BitmapEffect支援的型別轉換子,所以XAMLXAML您使用這個屬性的語法通常是屬性元素語法。No existing derived class of BitmapEffect supports a type converter, so the XAMLXAML syntax that you use for this property is generally property element syntax.
