Fx protocol provides an interface that the host application implements to allow for retrieving information about paths, shapes, and masks the user has drawn on an object.
- FxPlug 3.1+
Use this protocol to get information about a path that the user has drawn on an object in the canvas. You can get the number of paths applied to the object,and then enumerate through them or pick a specific one.
This protocol also allows retrieval of the control points along the path and that information can then be used to guide the rendering of a plug-in.
