Attributes

Name	Type	Default Value	Mandatory	Description
id	string	-	No	Unique ID of the component.
attributeName	string	-	No	Name of the component to which the animation is applied.
begin	<time>	0	No	Delay time of the animation. The value can be ms (ms), s (second), or m (minute). The default value is s (second). Other formats are not supported.
dur	<time>	0	No	Animation duration. If dur is not set, the value of end-begin is used as the duration. If the value is less than or equal to 0, the animation is not triggered. The value can be ms (ms), s (second), or m (minute). The default value is s (second). Other formats are not supported.
end	<time>	0	No	Duration after which the animation ends. The value can be ms (ms), s (second), or m (minute). The default value is s (second). Other formats are not supported.
repeatCount	<number \|indefinite>	1	No	Number of times the animation is played. The default value is indefinite. You can set the value to 1 to play the animation only once.
fill	<freeze \|remove>	remove	No	State when the animation ends.
calcMode	<discrete \|linear \|paced \|spline>	linear	No	Interpolation mode of the animation. discrete: The animation directly jumps from the value specified by from to the value specified by to. linear: Linear interpolation between values is used. paced: Interpolation that produces an even paced change is used. If this value is set, the values of keyTimes and keyPoints will not take effect. spline: Interpolation is implemented based on a custom Bezier spline. The spline points are defined in the keyTimes attribute, and the control points of each interval are defined in the keySplines attribute.
keyTimes	string	-	No	Start time of the key frame animation. The value is a semicolon-separated list of values ranging from 0 to 1, for example, 0;0.3;0.8;1. keyTimes, keySplines, and values are combined to set the key frame animation. The number of values defined for keyTimes is the same as that for values. The number of values defined for keySplines is the number of values defined for keyTimes minus 1.
keySplines	string	-	No	A set of Bezier control points associated with keyTimes. You can define the Bezier curves for each key frame, separating them with semicolons (;). The format of the two control points in the curve is x1 y1 x2 y2, for example, 0.5 0 0.5 1; 0.5 0 0.5 1;0.5 0 0.5 1.
by	number	-	No	Relative offset value to add to a specified attribute in the animation. The default value of from is the original attribute value.
from	string	-	No	Start value of the attribute to which the animation is applied. If the values attribute has been set, the from attribute is invalid.
to	string	-	No	End value of the attribute to which the animation is applied. If the values attribute has been set, the to attribute is invalid.
values	string	-	No	Change value of a group of animations. The format is value1;value2;value3.
