Sets or returns a Single that represents the rotation of an object by the specified number of degrees; for example, a value of 180 means to rotate the object by 180 degrees. Read/write.
Syntax
expression.By
expression A variable that represents a RotationEffect object.
Remarks
The specified object will be rotated with the center of the object remaining in the same position on the screen.
If both the By and To properties are set for a rotation effect, then the value of the By property is ignored.
Floating point numbers (for example, 55.5) are valid, but negative numbers are not.
Do not confuse this property with the ByX or ByY properties of the ScaleEffect and MotionEffect objects, which are only used for scaling or motion effects.
Example
This example adds a rotation effect and changes its rotation.
