IDCompositionScaleTransform interface
Represents a 2D transformation that affects the scale of a visual along the x-axis and y-axis. The coordinate system is scaled from the specified center point.
When to implement
Client applications do not implement IDCompositionScaleTransform; custom implementations are not supported.
Members
The IDCompositionScaleTransform interface inherits from IDCompositionTransform. IDCompositionScaleTransform also has these types of members:
Methods
The IDCompositionScaleTransform interface has these methods.
| Method | Description |
|---|---|
| SetCenterX | Overloaded. Changes or animates the value of the CenterX property of a 2D scale transform. |
| SetCenterY | Overloaded. Changes or animates the value of the CenterY property of a 2D scale transform. |
| SetScaleX | Overloaded. Changes or animates the value of the ScaleX property of a 2D scale transform. |
| SetScaleY | Overloaded. Changes or animates the value of the ScaleY property of a 2D scale transform. |
Remarks
A scale transform represents the following 3-by-3 matrix:

The effect is to scale the coordinate system up or down and apply the corresponding translation such that the center point does not move.
