Rotated rectangular 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.

w_in : float

Inner rectangle full width and height in pixels. w_in is measured along the inner rectangle’s local x axis, and h_in along its local y axis.

h_in : float

Inner rectangle full width and height in pixels. w_in is measured along the inner rectangle’s local x axis, and h_in along its local y axis.

w_out : float

Outer rectangle full width and height in pixels. w_out is measured along the outer rectangle’s local x axis, and h_out along its local y axis. Each outer dimension must be at least the corresponding inner dimension, and at least one outer dimension must be larger. At theta_out=0, the outer width axis is aligned with the image x axis and the outer height axis with the image y axis.

h_out : float

Outer rectangle full width and height in pixels. w_out is measured along the outer rectangle’s local x axis, and h_out along its local y axis. Each outer dimension must be at least the corresponding inner dimension, and at least one outer dimension must be larger. At theta_out=0, the outer width axis is aligned with the image x axis and the outer height axis with the image y axis.

theta_in : float = 0.0

Inner rectangle rotation angle in radians, measured counterclockwise from the positive image x axis to the inner rectangle’s local width axis.

theta_out : float = None

Outer rectangle rotation angle in radians, measured counterclockwise from the positive image x axis to the outer rectangle’s local width axis. If None, it defaults to theta_in.

validate : bool = True

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