BitmapDecoder.Frames 屬性

定義

取得點陣圖內個別畫面格的內容。

public:
 virtual property System::Collections::ObjectModel::ReadOnlyCollection<System::Windows::Media::Imaging::BitmapFrame ^> ^ Frames { System::Collections::ObjectModel::ReadOnlyCollection<System::Windows::Media::Imaging::BitmapFrame ^> ^ get(); };
public virtual System.Collections.ObjectModel.ReadOnlyCollection<System.Windows.Media.Imaging.BitmapFrame> Frames { get; }
member this.Frames : System.Collections.ObjectModel.ReadOnlyCollection<System.Windows.Media.Imaging.BitmapFrame>
Public Overridable ReadOnly Property Frames As ReadOnlyCollection(Of BitmapFrame)

屬性值

ReadOnlyCollection<BitmapFrame>

BitmapFrame 的執行個體。 此屬性沒有預設值。

範例

下列程式碼範例示範如何使用 BitmapFrame 做為 BitmapSource


// Open a Stream and decode a TIFF image
Stream imageStreamSource = new FileStream("tulipfarm.tif", FileMode.Open, FileAccess.Read, FileShare.Read);
TiffBitmapDecoder decoder = new TiffBitmapDecoder(imageStreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
BitmapSource bitmapSource = decoder.Frames[0];

// Draw the Image
Image myImage1 = new Image();
myImage1.Source = bitmapSource;
myImage1.Stretch = Stretch.None;
myImage1.Margin = new Thickness(20);
' Open a Stream and decode a TIFF image
Dim imageStreamSource As New FileStream("tulipfarm.tif", FileMode.Open, FileAccess.Read, FileShare.Read)
Dim decoder As New TiffBitmapDecoder(imageStreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default)
Dim bitmapSource As BitmapSource = decoder.Frames(0)

' Draw the Image
Dim myImage1 As New Image()
myImage1.Source = bitmapSource
myImage1.Stretch = Stretch.None
myImage1.Margin = New Thickness(20)

備註

只有標記的影像檔案格式 (TIFF) 和圖形交換格式 (GIF) 影像支援多個畫面。

此屬性傳回的任何 BitmapFrame 物件都已凍結。
