Hi all,
It is said in the specification
(http://w3c.github.io/web-animations/#typedef-cubic-bezier-timing-function)
cubic-bezier(<number>, <number>, <number>, <number>)
Specifies a cubic Bézier timing function. The four numbers specify
points P1 and P2 of the curve as (x1, y1, x2, y2). Both x values must
be in the range [0, 1] or the definition is invalid.
It is also said in the spec
(http://w3c.github.io/web-animations/#dom-animationtiming-easing) that:
Unrecognized string values or values that correspond to a timing function
that is not supported for the type of animation node to which this
property is applied are treated as if the linear keyword was specified for
the purpose of timing model calculations.
But it is not quite clear what behaviour should be if there are values
outside [0, 1] range and definition is invalid? Should invalid
cubic-bezier definition be treated as linear?
Yes, that's correct. Perhaps it would be more clear if I replaced
"Unrecognized string values" with "Unrecognized or invalid string values"?
I've made that change here:
https://github.com/w3c/web-animations/commit/7843a090ba9fdf2c85ce8429c7c2b754c2e64d1c
Please let me know if this addresses the problem.
Best regards,
Brian
