Image

Contains the leaves of the Image algebraic data type. Packaged here so they don't pollute the namespace when importing Image to access to the smart constructors.

Interpolate a spline (a curve) that passes through all the given points, using the Catmul Rom formulation (see, e.g., https://en.wikipedia.org/wiki/Cubic_Hermite_spline)

The tension can be changed to control how tightly the curve turns. It defaults to 0.5.

The Catmul Rom algorithm requires a point before and after each pair of points that define the curve. To meet this condition for the first and last points in points, they are repeated.

If points has less than two elements an empty Path is returned.

Compile an Image to a doodle.algebra.Picture

Construct an open path of bezier curves that intersects all the given points. Defaults to catmulRom with the default tension.
