RotateImage:Void image:Int32, angle:Float32

Parameter	Mode	Type	Default	Description
image	In	Int32	required	The image.
angle	In	Float32	required	The angle in degrees.

Description

Turns every frame of an image around its handle by an angle in degrees, clockwise when positive. The image gets larger so that the whole picture fits, and the corners that are added are masked. The change is permanent and cumulative, and every rotation blurs the picture a little, so rotate a copy of the original image.
