HOW TO：旋轉影像
更新：2007 年 11 月
本範例示範如何使用 BitmapImage 的 Rotation 屬性，將影像旋轉 90 度。
範例
<Image Width="150" Margin="5" Grid.Column="0" Grid.Row="1">
<Image.Source>
<BitmapImage UriSource="/sampleImages/watermelon.jpg" Rotation="Rotate90" />
</Image.Source>
</Image>
'Create Image element
Dim rotated270 As New Image()
rotated270.Width = 150
'Create source
Dim bi As New BitmapImage()
'BitmapImage properties must be in a BeginInit/EndInit block
bi.BeginInit()
bi.UriSource = New Uri("pack://application:,,/sampleImages/watermelon.jpg")
'Set image rotation
bi.Rotation = Rotation.Rotate270
bi.EndInit()
'set image source
rotated270.Source = bi
//Create Image element
Image rotated270 = new Image();
rotated270.Width = 150;
//Create source
BitmapImage bi = new BitmapImage();
//BitmapImage properties must be in a BeginInit/EndInit block
bi.BeginInit();
bi.UriSource = new Uri(@"pack://application:,,/sampleImages/watermelon.jpg");
//Set image rotation
bi.Rotation = Rotation.Rotate270;
bi.EndInit();
//set image source
rotated270.Source = bi;
