The keySplines attribute define a set of Bézier control points associated with the keyTimes
list, defining a cubic Bézier function that controls interval pacing. The attribute value is a semicolon-separated list of control point descriptions. Each control point description is a set of four values: x1 y1 x2 y2
, describing the Bézier control points for one time segment. The keyTimes
values that define the associated segment are the Bézier "anchor points", and the keySplines
values are the control points. Thus, there must be one fewer sets of control points than there are keyTimes
.
The values of x1 y1 x2 y2
must all be in the range 0 to 1.
This attribute is ignored unless the calcMode
is set to spline
.
If there are any errors in the keySplines specification (bad values, too many or too few values), the animation will not occur.
