property Layer.RotamoveCenterY as Long
Specifies the y-position of the layer's center, while the layer's drag operation is exDoRotamove.

TypeDescription
Long A Long expression that specifies the x-position of the layer's center

By default the RotamoveCenterX / RotamoveCenterY indicates the (x,y)-center of the layer's view. 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 LayerToClientX / LayerToClientY properties translate a point from the layer ( as it is moved or rotated ) to the control's view.

The center of the layer may be different than layer's view, as for instance, if you have a layer that's shows a knob in the bottom-side of the layer the RotamoveCenterX / RotamoveCenterY point is the center on the knob in the bottom-right side not in the center of the layer as you can see in the following screen shot ( red cross ) :

 

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

The following picture shows the rotamove properties of the Layer, relative to the RotateCenterLayer layer:

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

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