The control supports moving the layer by rotation, also called rotamove. The rotamove operation moves layer and the rotamove center pointed by RotamoveCenterX / RotamoveCenterY properties around the rotation center pointed by the RotateCenterX / RotateCenterY properties of the RotateCenterLayer layer. The following picture shows the rotamove properties of the Layer, relative to the RotateCenterLayer layer:

The following properties can be used to change the rotation center, while the layer's OnDrag property is exDoRotamove:

• RotamoveCenterX, specifies the x-position of the layer's center ( view ).
• RotamoveCenterY, specifies the y-position of the layer's center  ( view ). 
• RotamoveOffsetX,  specifies the x-offset of the layer.
• RotamoveOffsetY, specifies the y-offset of the layer.

Any of the following properties can be used to rotate the layer:

• DefaultRotateAngle, specifies the default angle to rotate the layer.
• RotateAngle, specifies the angle to rotate the layer.
• RotateAngleValid, validates / limits the rotation angle of the layer.
• Value and ValueToRotateAngle, specifies the expression to convert the value to rotating angle. The RotateAngleToValue converts the current rotation angle to a value.

The following properties can be used to specify a different rotation center:

• RotateCenterLayer, indicates the index of the layer the rotation is around.
• RotateCenterX, indicates the expression that determines the x-origin of the rotation point relative to the RotateCenterLayer layer.
• RotateCenterY, indicates the expression that determines the y-origin of the rotation point relative to the RotateCenterLayer layer.
