Valore della proprietà

Istanza di BitmapFrame. Nessun valore predefinito per questa proprietà.

Esempio

Nell'esempio di codice seguente viene illustrato come usare un BitmapFrameBitmapSourceoggetto come .

// 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)

Commenti
