Shape#

class random_shapes.Shape(curve: CurvedPolygon)[source]#

Bases: object

A wrapper class of bezier.CurvedPolygon for creating random bezier shapes and convertion to other formats.

classmethod from_points(points: list[Point], edgy: float, r: float) → Self[source]#

Get a bezier shape from a list of points.

Parameters:

  • points (list[Point]) – A list of points.

  • edgy (float, optional) – A number between 0 and 1 to steer the edgyness / weiredness of the shape.

  • r (float, optional) – A number between 0 and 1 to steer the roundness of the shape-edges.

classmethod random(n: int = 5, r: float = 0.3, edgy: float = 0, scale: float = 0.8, mindst: float | None = None, rec: int = 0) → Self[source]#

Create a random shape.

Parameters:

  • n (int, optional) – Number of points. Defaults to 5.

  • edgy (float, optional) – Steers the edgyness / weiredness of the shape. Defaults to 0.

  • r (float, optional) – Steers the roundness of the shape-edges. Defaults to 0.3.

  • scale (float, optional) – Scaling factor. Defaults to 0.8.

  • mindst (float, optional) – Minimum distance between points. Defaults to None.

  • rec (int, optional) – Recursion counter for the random generation of points. Defaults to 0.

Returns:

A random shape.

Return type:

bezier.CurvedPolygon

rasterize(w: int, h: int, pts_per_edge: int = 20) → ndarray[source]#

Convert a bezier shape to a binary image.

Parameters:

  • shape (bezier.CurvedPolygon) – A bezier shape.

  • w (int) – Width of the image.

  • h (int) – Height of the image.

  • pts_per_edge (int, optional) – Number of points per edge. Defaults to 20.

Returns:

A binary image of the shape.

Return type:

np.ndarray
