Fields
| Name | Value | Description |
|---|---|---|
| Rotate0 | 0 | The bitmap is not rotated. This is the default value. |
| Rotate90 | 1 | Rotate the bitmap clockwise by 90 degrees. |
| Rotate180 | 2 | Rotate the bitmap clockwise by 180 degrees. |
| Rotate270 | 3 | Rotate the bitmap clockwise by 270 degrees. |
Examples
The following example demonstrates how to apply a rotation to a bitmap image.
// Define a BitmapImage.
Image myImage = new Image();
BitmapImage bi = new BitmapImage();
// Begin initialization.
bi.BeginInit();
// Set properties.
bi.CacheOption = BitmapCacheOption.OnDemand;
bi.CreateOptions = BitmapCreateOptions.DelayCreation;
bi.DecodePixelHeight = 125;
bi.DecodePixelWidth = 125;
bi.Rotation = Rotation.Rotate90;
MessageBox.Show(bi.IsDownloading.ToString());
bi.UriSource = new Uri("smiley.png", UriKind.Relative);
// End initialization.
bi.EndInit();
myImage.Source = bi;
myImage.Stretch = Stretch.None;
myImage.Margin = new Thickness(5);
' Define a BitmapImage.
Dim myImage As New Image()
Dim bi As New BitmapImage()
' Begin initialization.
bi.BeginInit()
' Set properties.
bi.CacheOption = BitmapCacheOption.OnDemand
bi.CreateOptions = BitmapCreateOptions.DelayCreation
bi.DecodePixelHeight = 125
bi.DecodePixelWidth = 125
bi.Rotation = Rotation.Rotate90
MessageBox.Show(bi.IsDownloading.ToString())
bi.UriSource = New Uri("smiley.png", UriKind.Relative)
' End initialization.
bi.EndInit()
myImage.Source = bi
myImage.Stretch = Stretch.None
myImage.Margin = New Thickness(5)
Remarks
Only 90 degree increments are supported.
