pythagoras.utils module

class pythagoras.utils.Phantom(x: float, y: float, zord: int = 0)

Bases: PObject

A zero-size placeholder element used for layout or reference.

Variables:

• x (float) – \(x\)-coordinate in Cartesian space.

• y (float) – \(y\)-coordinate in Cartesian space.

extrema() → list[tuple[float, float]]

Computes the furthermost points of the figure.

Returns:

A list with the bounding points of the object.

svg(ctx: RenderingContext, *args: POProperty) → str

Compiles the object into SVG commands.

Parameters:

• ctx – Context associated with the Canvas instance.

• args – Properties of the object.

Returns:

The corresponding SVG code.

tikz(ctx: RenderingContext, *args: POProperty) → str

Compiles the object into a sequence of TikZ instructions.

Parameters:

• ctx – Context associated with the Canvas instance.

• args – Properties of the object.

Returns:

The resulting TikZ code.

x: float

y: float

pythagoras.utils.cartesian_to_canvas(p: tuple[float, float], ctx: RenderingContext) → tuple[float, float]

Converts a point in Cartesian coordinates into the canvas coordinate system.

Parameters:

• p – Point to be converted.

• ctx – Properties associated to the canvas.

Returns:

The point in canvas coordinates.
