The properties of the Rotation group allow defining the initial rotation angle of animation and an optional expression to dynamically control the rotation angle at runtime. They also allow you to define the position of the center of rotation.



These properties are not available for the animation belonging to Objects category.


Center of rotation

Allows you to define the position of the center of rotation by selecting a default or allowing customization. Selecting "Custom" the center of rotation will be placed in the coordinates defined by the properties X position andY position, relating to the upper-left corner of the animation.

Possible choices:
  • Center
  • Top-left
  • Top-center
  • Top-right 
  • Center-left
  • Center-right
  • Bottom-left
  • Bottom-center
  • Bottom-right
  • Custom

X Position

This property is visible and takes effect only if Center of rotation is set to "Custom". Specifies the horizontal coordinate of the rotation center with respect to the upper-left corner of the animation.

Y Position 

This property is visible and takes effect only if Center of rotation is set to "Custom". Specifies the vertical coordinate of the center of rotation with respect to the upper-left corner of the animation.

Initial angle

Allows you to specify the static rotation angle of the object, expressed in degrees. If the Rotation (Expression) property has been filled in, the value computed by the expression will prevail with respect to the value assigned to this property.

Rotation (Expression)

Specifies an expression to be computed as the value of the rotation angle of the animation, expressed in degrees (decimal allowed).
