an.adapters.cutout.channel

Channel evaluation — moved to an.timing.channel (the timing kernel).

This path keeps working for every existing caller; new code imports from an.timing. **This module’s names are the executable spec of runtime.js’s evaluateChannel``** (with the default ``kind=None: by value type), pinned by tests/test_cutout_channel_parity.py.

>>> ch = Channel("a", "x", [Keyframe(0.0, 0.0), Keyframe(1.0, 10.0)])
>>> evaluate(ch, 0.5)
5.0

Functions

evaluate(channel, t, *[, kind])	Evaluate channel at time t (see the module docstring for kind).
check_channel(channel, kind)	Why channel's keyframe values do not fit kind (empty if they do).

Classes

Channel(target, property[, keyframes])	Sorted keyframes for one property of one target.
Keyframe(time, value[, easing])	One keyframe: time, value, optional per-segment easing.

class an.adapters.cutout.channel.Channel(target, property, keyframes=<factory>)

Bases: object

Sorted keyframes for one property of one target.

Construction validates that keyframes is non-empty and sorted.

class an.adapters.cutout.channel.Keyframe(time, value, easing=None)

Bases: object

One keyframe: time, value, optional per-segment easing.

The easing on a keyframe describes the curve leaving that keyframe toward the next one. The last keyframe’s easing is therefore unused.

an.adapters.cutout.channel.check_channel(channel, kind)

Why channel’s keyframe values do not fit kind (empty if they do).

Return type:

list[str]

an.adapters.cutout.channel.evaluate(channel, t, *, kind=None)

Evaluate channel at time t (see the module docstring for kind).

Return type:

Any
