XAML Values

Property Value

Type: System.Windows.Media.Transform
Describes the specifics of the desired render transform. The default value is nulla null reference (Nothing in Visual Basic).


Dependency property identifier field: RenderTransformProperty

The Transform object can either be a single type of transform (such as RotateTransform) or a TransformGroup. The TransformGroup is not a transform per se, but is instead a container that enables you to specify more than one transform for a RenderTransform as markup children in XAML, or by adding transform items to the Children collection in code.

The local 0,0 for an object can be offset on a Canvas using Canvas.Left and Canvas.Top, but this does not count as a transform; the object retains its own local 0,0 in this case for transform purposes.

The render transform origin can also be offset with RenderTransformOrigin.


The following XAML defines a Matrix that provides data for a MatrixTransform applied to a rectangular shape as its RenderTransform. In this case, the matrix combines an offset (OffsetX and OffsetY) and a skew (M12). Note that this same effect could have been produced by combining a TranslateTransform and a SkewTransform; whether to use a single Matrix or combinations of discrete transforms (with TransformGroup) is a matter of coding style, the results are identical.

<Rectangle Width="60" Height="60" Fill="Blue">
      <MatrixTransform.Matrix >

        <!-- This matrix transforms the x,y position of
             the rectangle and skews it. -->
        <Matrix OffsetX="30" OffsetY="100" M12="0.5" />
