Rotate

Rotates the image.

See also Affine Transition that can also achieve a similar effect.

The units of rotation are tenths of a degree. eg 1800 = 180 degree rotation.

Rotate X rotates the frame in the plane of the screen.

Rotate Y and Rotate Z create the illusion of 3D rotation when used dynamically with keyframes.

The difference between rotate Y and rotate Z is that the apparent rotation in rotate Y appears to be around a horizontal axis. The rotation in rotate Z appears to be around a vertical axis.
