範例

// Set the stretch property.
myImage1.Stretch = Stretch.Fill;

// Set the StretchDirection property.
myImage1.StretchDirection = StretchDirection.Both;

// Create source
BitmapImage myBitmapImage1 = new BitmapImage();

myBitmapImage1.BeginInit();
myBitmapImage1.UriSource = new Uri(@"C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Winter.jpg");
myBitmapImage1.EndInit();

//set image source
myImage1.Source = myBitmapImage1;
Dim myImage1 As New Image()

' Set the stretch property.
myImage1.Stretch = Stretch.Fill

' Set the StretchDirection property.
myImage1.StretchDirection = StretchDirection.Both

' Create source
Dim myBitmapImage1 As New BitmapImage()

' BitmapImage.UriSource must be in a BeginInit/EndInit block
myBitmapImage1.BeginInit()
myBitmapImage1.UriSource = New Uri("C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Winter.jpg")
myBitmapImage1.EndInit()

'set image source
myImage1.Source = myBitmapImage1

備註

的值 Fill 會導致您的影像完全填滿輸出區域。 當輸出區域和影像的外觀比例不相同時,影像就會因為自動縮放而扭曲。 若要保留 Image 影像的外觀比例,請將此屬性設定為 Uniform (預設) 或 UniformToFill
