The rotate attribute specifies how the animated element rotates as it travels along a path specified in an <animateMotion> element.

Usage notes

Value auto | auto-reverse | <number>
Default value 0
Animatable No

The auto and auto-reverse values allow the animated element's rotation to change dynamically as it travels along the path. If the value of rotate is auto, the element turns to align its right-hand side in the current direction of motion. If the value is auto-reverse, it turns its left-hand side in the current direction of motion.

Setting rotate's value to a number specifies a constant rotation, in degrees, that does not change with the animation. The default value of 0 keeps the animated element in its original orientation.
