Examples

This example shows how to apply the same transforms to an object by using either a CompositeTransform or a TransformGroup.

<StackPanel Margin="50">
    <Canvas Background="Black" Width="200" Height="200">
        <Rectangle Height="100" Width="100" Fill="Red">
            <Rectangle.RenderTransform>

                <!-- This one line of markup is the equivalent of the entire
             TransformGroup block in the other Canvas below. -->
                <CompositeTransform SkewX="30" Rotation="45" ScaleX="0.8" ScaleY="0.8" />
            </Rectangle.RenderTransform>
        </Rectangle>
    </Canvas>

    <Canvas Margin="10" Background="Black" Width="200" Height="200">
        <Rectangle Height="100" Width="100" Fill="Red">
            <Rectangle.RenderTransform>
                <TransformGroup>

                    <!-- Note that you have to apply these transforms in 
                     a specific order to get the same effect as the
                     CompositeTransform. -->
                    <ScaleTransform ScaleX="0.8" ScaleY="0.8" />
                    <SkewTransform AngleX="30" />
                    <RotateTransform Angle="45" />
                </TransformGroup>
            </Rectangle.RenderTransform>
        </Rectangle>
    </Canvas>
</StackPanel>

Remarks

CompositeTransform applies multiple transforms in this order:

  1. Scale (ScaleX, ScaleY )
  2. Skew (SkewX, SkewY )
  3. Rotate (Rotation )
  4. Translate (TranslateX, TranslateY )

If you want to apply multiple transforms to an object in a different order, you can create a TransformGroup and insert the transforms in your intended order.

CompositeTransform uses the same center point (CenterX, CenterY ) for all transformations. If you want to specify different center points per transform, use TransformGroup.

Constructors

CompositeTransform() CompositeTransform() CompositeTransform() CompositeTransform()

Initializes a new instance of the CompositeTransform class.

Properties

CenterX CenterX CenterX CenterX

Gets or sets the x-coordinate of the center point for all transforms specified by the CompositeTransform in device-independent pixel (DIP) relative to the upper left-hand corner of the element.

CenterXProperty CenterXProperty CenterXProperty CenterXProperty

Identifies the CenterX dependency property.

CenterY CenterY CenterY CenterY

Gets or sets the y-coordinate of the center point for all transforms specified by the CompositeTransform in device-independent pixel (DIP) relative to the upper left-hand corner of the element.

CenterYProperty CenterYProperty CenterYProperty CenterYProperty

Identifies the CenterY dependency property.

Dispatcher Dispatcher Dispatcher Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

(Inherited from DependencyObject)
Inverse Inverse Inverse Inverse

Gets the inverse transformation of this GeneralTransform, if possible.

(Inherited from GeneralTransform)
InverseCore InverseCore InverseCore InverseCore

Implements the behavior for return value of Inverse in a derived or custom GeneralTransform.

(Inherited from GeneralTransform)
Rotation Rotation Rotation Rotation

Gets or sets the angle, in degrees, of clockwise rotation.

RotationProperty RotationProperty RotationProperty RotationProperty

Identifies the Rotation dependency property.

ScaleX ScaleX ScaleX ScaleX

Gets or sets the x-axis scale factor. You can use this property to stretch or shrink an object horizontally.

ScaleXProperty ScaleXProperty ScaleXProperty ScaleXProperty

Identifies the ScaleX dependency property.

ScaleY ScaleY ScaleY ScaleY

Gets or sets the y-axis scale factor. You can use this property to stretch or shrink an object vertically.

ScaleYProperty ScaleYProperty ScaleYProperty ScaleYProperty

Identifies the ScaleY dependency property.

SkewX SkewX SkewX SkewX

Gets or sets the x-axis skew angle, which is measured in degrees counterclockwise from the y-axis. A skew transform can be useful for creating the illusion of three-dimensional depth in a two-dimensional object.

SkewXProperty SkewXProperty SkewXProperty SkewXProperty

Identifies the SkewX dependency property.

SkewY SkewY SkewY SkewY

Gets or sets the y-axis skew angle, which is measured in degrees counterclockwise from the x-axis. A skew transform can be useful for creating the illusion of three-dimensional depth in a two-dimensional object.

SkewYProperty SkewYProperty SkewYProperty SkewYProperty

Identifies the SkewY dependency property.

TranslateX TranslateX TranslateX TranslateX

Gets or sets the distance to translate along the x-axis.

TranslateXProperty TranslateXProperty TranslateXProperty TranslateXProperty

Identifies the TranslateX dependency property.

TranslateY TranslateY TranslateY TranslateY

Gets or sets the distance to translate (move) an object along the y-axis.

TranslateYProperty TranslateYProperty TranslateYProperty TranslateYProperty

Identifies the TranslateY dependency property.

(Inherited from DependencyObject)
TransformBounds(Rect) TransformBounds(Rect) TransformBounds(Rect) TransformBounds(Rect)

Transforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it.

(Inherited from GeneralTransform)
TransformBoundsCore(Rect) TransformBoundsCore(Rect) TransformBoundsCore(Rect) TransformBoundsCore(Rect)

Provides the means to override the TransformBounds behavior in a derived transform class.

(Inherited from GeneralTransform)
