IDCompositionRotateTransform interface
Represents a 2D transformation that affects the rotation of a visual around the z-axis. The coordinate system is rotated around the specified center point.
When to implement
Client applications do not implement IDCompositionRotateTransform; custom implementations are not supported.
Members
The IDCompositionRotateTransform interface inherits from IDCompositionTransform. IDCompositionRotateTransform also has these types of members:
Methods
The IDCompositionRotateTransform interface has these methods.
| Method | Description |
|---|---|
| SetAngle | Overloaded. Changes or animates the value of the Angle property of a rotation transform. The Angle property specifies the rotation angle, in degrees. The default value is zero. |
| SetCenterX | Overloaded. Changes or animates the value of the CenterX property of a 2D rotation transform. |
| SetCenterY | Overloaded. Changes or animates the value of the CenterY property of a 2D rotation transform. |
Remarks
A rotate transform represents the following 3-by-3 matrix:

The effect is to rotate the coordinate system clockwise or counter-clockwise, and to apply the corresponding translation such that the center point does not move.
