Valor de propiedad

Transform

Clase Transform que especifica la escala o la rotación del mapa de bits. El valor predeterminado es Identity.

Ejemplos

En el ejemplo siguiente se muestra cómo aplicar un Transform objeto a un mapa de bits.

<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

Comentarios

TransformedBitmap solo admite transformaciones ortogonales, como transformaciones de rotación de 90 incrementos y transformaciones de escala. No se admiten transformaciones que sesgarán la imagen.
