The TranslateTransform type exposes the following members.

  NameDescription
Public methodTranslateTransformInitializes a new instance of the TranslateTransform class.
Top

  NameDescription
Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyInverseGets the inverse of this transform, if it exists. (Inherited from Transform.)
Public propertyXGets or sets the distance to translate along the x-axis.
Public propertyYGets or sets the distance to translate (move) an object along the y-axis.
Top

  NameDescription
Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodTransformTransforms the specified point and returns the result. (Inherited from GeneralTransform.)
Public methodTransformBoundsTransforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it. (Inherited from Transform.)
Public methodTryTransformAttempts to transform the specified point and returns a value that indicates whether the transformation was successful. (Inherited from Transform.)

  NameDescription
Public fieldStatic memberXPropertyIdentifies the X dependency property.
Public fieldStatic memberYPropertyIdentifies the Y dependency property.

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).

TranslateTransform matrix

Matrix.

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.

TextBlock using a TranslateTransform

Translated text creates text shadow.

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.


<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.


    <Canvas
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
     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;
}
