calcMode attribute specifies the interpolation mode for the animation.

默认模式为 linear , however if the attribute does not support linear interpolation (e.g. for strings), the calcMode attribute is ignored and discrete interpolation is used.

You can use this attribute with the following SVG elements:

• <animate>
• <animateColor>
• <animateMotion>
• <animateTransform>

用法注意事项

值	discrete | linear | paced | spline
默认值	linear
Animatable	No

discrete

This specifies that the animation function will jump from one value to the next without any interpolation.

linear

Simple linear interpolation between values is used to calculate the animation function. Except for <animateMotion> , this is the default value.

paced

Defines interpolation to produce an even pace of change across the animation. This is only supported for values that define a linear numeric range, and for which some notion of "distance" between points can be calculated (e.g. position, width, height, etc.). If paced is specified, any keyTimes or keySplines will be ignored. For <animateMotion> , this is the default value.

spline

Interpolates from one value in the values list to the next according to a time function defined by a cubic Bézier spline. The points of the spline are defined in the keyTimes attribute, and the control points for each interval are defined in the keySplines 属性。
