bool

AutoRepeat

Sets or gets whether to turn on/off animation looping. If AutoRepeat is true, it repeats animation when animation frame is reached to end. This AutoRepeat mode is valid to both Play and ReversePlay cases.

Declaration

public bool AutoRepeat { get; set; }

Property Value

Type	Description
bool

DefaultSize

Get the default view size that specified from vector resource.

Declaration

public Size DefaultSize { get; }

Property Value

Type	Description
Size

DurationTime

Get the duration of animation in seconds.

Declaration

public double DurationTime { get; }

Property Value

Type	Description
double

Remarks

Returns total duration time of current animation in the seconds. If current animation source isn't animatable, it returns zero.

Frame

double

Speed

Sets or gets the animation speed. Control animation speed by multiplying Speed value. If you want to play animation double-time faster, you can give Speed 2. If you want to play animation double-time slower, you can give Speed 0.5. Speed must be greater than zero.
