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).
Typical 3x3 matrix for 2-D translations
Freezable Features: Because it inherits from the Freezable class, the TranslateTransform class provides several special features: TranslateTransform objects can be declared as resources, shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see Freezable Objects Overview.
This example shows how to translate (move) an element by using a TranslateTransform.
The TranslateTransform class is especially useful for moving elements inside panels that do not support absolute positioning. For example, by applying a TranslateTransform to the RenderTransform property of an element, you can move an element within a StackPanel or DockPanel.
Use the X property of the TranslateTransform to specify the amount, in pixels, to move the element along the x-axis. Use the Y property to specify the amount, in pixels, to move the element along the y-axis. Finally, apply the TranslateTransform to the RenderTransform property of the element.
The following example uses a TranslateTransform to move an element 50 pixels to the right and 50 pixels down.
