Properties

	Name	Description
	Dispatcher	Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
	Inverse	Gets the inverse of this transform, if it exists. (Inherited from Transform.)
	X	Gets or sets the distance to translate along the x-axis.
	Y	Gets or sets the distance to translate (move) an object along the y-axis.

Methods

	Name	Description
	CheckAccess	Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
	ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetAnimationBaseValue	Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
	SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Transform	Transforms the specified point and returns the result. (Inherited from GeneralTransform.)
	TransformBounds	Transforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it. (Inherited from Transform.)
	TryTransform	Attempts to transform the specified point and returns a value that indicates whether the transformation was successful. (Inherited from Transform.)

Fields

	YProperty	Identifies the Y dependency property.

Remarks

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.

Multiple transforms can be applied with a TransformGroup. Custom transforms can be created with a MatrixTransform.

TranslateTransform defines an axis-aligned translation along the x and y axes. The following illustration shows the transformation matrix for a translation by offset (dx, dy).

Transforms can alter the display of text in your application to create a decorative effect. The following illustration shows text translated, or moved, along the x and y axes.

Examples

The following example uses a TranslateTransform to offset text. In this example, a slightly offset copy of text below the primary text creates a shadow effect.

Run this sample

<Canvas>

      <!-- Offset the text using a TranslateTransform. -->
      <TextBlock
       FontFamily="Verdana"
       FontSize="32"
       FontWeight="Bold" 
       Foreground="Black"
       Text="Translated Text">
          <TextBlock.RenderTransform>
              <TranslateTransform X="2" Y="2" />
          </TextBlock.RenderTransform>
      </TextBlock>

      <TextBlock
       FontFamily="Verdana"
       FontSize="32"
       FontWeight="Bold" 
       Foreground="Coral"
       Text="Translated Text"/>

  </Canvas>

The example below shows how to increase the X and Y property values of a TranslateTransform applied to a Rectangle every time the Rectangle is clicked.

Run this sample

<Canvas
 xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
 Width="200" Height="200">
    <Rectangle MouseLeftButtonDown="handleMouseButtonDown"
     Width="50" Height="50" Fill="RoyalBlue">
        <Rectangle.RenderTransform>

            <!-- If you give the transform a name you can access it easily
       from code. -->
            <TranslateTransform x:Name="myTranslateTransform" />
        </Rectangle.RenderTransform>
    </Rectangle>
</Canvas>

private void handleMouseButtonDown(object sender, EventArgs e)
{

    // Increase the X and Y properties.
    myTranslateTransform.X = myTranslateTransform.X + 15;
    myTranslateTransform.Y = myTranslateTransform.Y + 15;
}
