TransformedBitmap.Transform Eigenschap

public:
 property System::Windows::Media::Transform ^ Transform { System::Windows::Media::Transform ^ get(); void set(System::Windows::Media::Transform ^ value); };

public System.Windows.Media.Transform Transform { get; set; }

member this.Transform : System.Windows.Media.Transform with get, set

Public Property Transform As Transform

Waarde van eigenschap

De Transform, waarmee de schaal of draaiing van de bitmap wordt opgegeven. De standaardwaarde is Identity.

Voorbeelden

In het volgende voorbeeld ziet u hoe u een Transform bitmap toepast.

<Image Width="150" Margin="5" Grid.Column="0" Grid.Row="1">
  <Image.Source>
    <TransformedBitmap Source="/sampleImages/watermelon.jpg" >
      <TransformedBitmap.Transform>
        <RotateTransform Angle="90"/>
      </TransformedBitmap.Transform>
    </TransformedBitmap>
  </Image.Source>
</Image>

// Create Image element.
Image rotated90 = new Image();
rotated90.Width = 150;

// Create the TransformedBitmap to use as the Image source.
TransformedBitmap tb = new TransformedBitmap();

// Create the source to use as the tb source.
BitmapImage bi = new BitmapImage();
bi.BeginInit();
bi.UriSource = new Uri(@"sampleImages/watermelon.jpg", UriKind.RelativeOrAbsolute);
bi.EndInit();

// Properties must be set between BeginInit and EndInit calls.
tb.BeginInit();
tb.Source = bi;
// Set image rotation.
RotateTransform transform = new RotateTransform(90);
tb.Transform = transform;
tb.EndInit();
// Set the Image source.
rotated90.Source = tb;

' Create Image element.
Dim rotated90 As New Image()
rotated90.Width = 150

' Create the TransformedBitmap to use as the Image source.
Dim tb As New TransformedBitmap()

' Create the source to use as the tb source.
Dim bi As New BitmapImage()
bi.BeginInit()
bi.UriSource = New Uri("sampleImages/watermelon.jpg", UriKind.RelativeOrAbsolute)
bi.EndInit()

' Properties must be set between BeginInit and EndInit calls.
tb.BeginInit()
tb.Source = bi
' Set image rotation.
Dim transform As New RotateTransform(90)
tb.Transform = transform
tb.EndInit()
' Set the Image source.
rotated90.Source = tb

Opmerkingen

TransformedBitmap ondersteunt alleen orthogonale transformaties, zoals rotatietransformaties van 90 stappen en schaaltransformaties. Transformaties die scheeftrekken van de afbeelding worden niet ondersteund.
