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.

Methods

The IDCompositionRotateTransform interface has these methods.

Method Description
IDCompositionRotateTransform::SetAngle Changes the value of the Angle property of a 2D rotation transform. The Angle property specifies the rotation angle.
IDCompositionRotateTransform::SetAngle Animates the value of the Angle property of a 2D rotation transform. The Angle property specifies the rotation angle.
IDCompositionRotateTransform::SetCenterX Changes the value of the CenterX property of a 2D rotation transform.
IDCompositionRotateTransform::SetCenterX Animates the value of the CenterX property of a 2D rotation transform.
IDCompositionRotateTransform::SetCenterY Changes the value of the CenterY property of a 2D rotation transform.
IDCompositionRotateTransform::SetCenterY Animates the value of the CenterY property of a 2D rotation transform.

Remarks

A rotate transform represents the following 3-by-3 matrix:

Three-by-three transformation 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.
