calcmode

This attribute specifies the interpolation mode for the animation. The default mode is linear, however if the attribute does not support linear interpolation (e.g. for strings), the calcMode attribute is ignored and discrete interpolation is used.

Usage context

Categories	Animation value attribute
Value	discrete | linear | paced | spline
Animatable	No
Normative document	SVG 1.1 (2nd Edition)

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 attribute.

Example

Elements
