Splines node
The Splines node outputs a simple RGBA image containing any number of splines defined by control points

Inputs
The Splines node accepst an optional image to map onto the splines with the Edge parameter, and an optional image to fill the inside area of a spline with the Fill input.
Additionally, the Guide input can be used to add a transparent image in the splines editor to guide point placement.
Outputs
The Splines node generates an RGBA image containing any number of splines, with the optional inputs mapped onto them
Parameters
The Splines node has the following parameters:
the control points that define the splines
the width of the curve to be drawn, which is set per control point
the offset defines how the edge image is offset at each control point
Notes
When selecting points, Ctrl-clicking can be used to select multiple control points, and Shift-clicking control points will select every point along the path.
Enabling the Progressive option will interpolate between all selected control points any changes done to width and offset
