tb_cx_phase — 2D typed op

• Data kinds: cimage → image

• Call: fullseye.apply(img, "tb_cx_phase", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

Wrapped phase of `cx -> real (H, W)` float64.

`display=True (default) maps the wrapped phase angle(cx)` in

`(-pi, pi] to [0, 1]` for viewing, with 0.5 at zero phase

(`(angle + pi) / (2*pi): -pi -> 0, 0 -> 0.5, +pi -> 1`).

`display=False returns the **raw wrapped radians** in (-pi, pi]` — the

quantity :func:cx_from_mag_phase and :func:phase_unwrap consume. Note the

default output is *wrapped* and *display-scaled*; :func:phase_unwrap returns

raw, continuous, un-scaled radians instead.

Typed bridge of the 2d op `cx_phase into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
