Elliptical annulus in pixel coordinates.

Parameters

positions : tuple or array - like

Annulus center or centers as (x, y) pixel coordinates. Multiple centers are accepted as an (N, 2) array-like object. Coordinates are copied into owned, read-only float64 storage. Editing the input does not move the aperture; construct a new aperture to change centers. The positions attribute cannot be reassigned. C-order, Fortran-order, and strided inputs are accepted. Input (x, y) gives scalar sums; [(x, y)] gives length-one vector sums.

a_in : float

Inner ellipse semiaxes in pixels.

b_in : float

Inner ellipse semiaxes in pixels.

a_out : float

Outer ellipse semiaxes in pixels. Each outer axis must be at least the corresponding inner axis, and at least one outer axis must be larger.

b_out : float

Outer ellipse semiaxes in pixels. Each outer axis must be at least the corresponding inner axis, and at least one outer axis must be larger.

theta_in : float = 0.0

Inner and outer rotation angles in radians, measured counterclockwise from the positive x axis. If theta_out is None, it defaults to theta_in.

theta_out : float = 0.0

Inner and outer rotation angles in radians, measured counterclockwise from the positive x axis. If theta_out is None, it defaults to theta_in.

validate : bool = True

If False, skip input validation and assume finite, positive geometry, ordered axes, and finite positions with shape (2,) or (N, 2). Coordinates are still copied and converted to float64.
