Region Layer
From Synfig Studio :: Documentation
The region layer is much like the Outline Layer, except that the shapes it describes are filled in, rather than just being an outline.
The parameters are exactly the same as in the [[Outline Layer], except that region layers don't have the last 7 parameters, which are all specific to outlines:
- Outline Width
- Expand
- Sharp Cusps
- Rounded Begin
- Rounded End
- Loopyness
- Homogeneous
The Outline Layer page is currently much more complete than this page, so please see that for details.
