LottieAnimationView

Implements

System.ComponentModel.INotifyPropertyChanged

System.IDisposable

Constructors

LottieAnimationView(float, bool)

LottieAnimationView constructor

Declaration

public LottieAnimationView(float scale = 1, bool shown = true)

Parameters

Type	Name	Description
float	scale	The factor of scaling image, default : 1.0f
bool	shown	false : not displayed (hidden), true : displayed (shown), default : true

Remarks

If the shown parameter is false, the animation is not visible even if the LottieAnimationView instance is created.

Examples

LottieAnimationView myLottie = new LottieAnimationView();
LottieAnimationView myLottie2 = new LottieAnimationView(2.0f);
LottieAnimationView myLottie3 = new LottieAnimationView(1.0f, false);

Properties

CurrentFrame

Set or get the current frame. When setting a specific frame, it is displayed as a still image.

Declaration

public int CurrentFrame { get; set; }

Property Value

Type	Description
int

Remarks

Gets the value set by a user. If the setting value is out-ranged, it is reset as a minimum frame or a maximum frame.

Examples

We assume that the animation in myLottie.json file has 100 frames originally. If so, its frame index will be 0 - 99.

LottieAnimationView myLottie = new LottieAnimationView();
myLottie.URL = Tizen.Applications.Application.Current.DirectoryInfo.Resource + "myLottie.json"; //myLottie.json's total frame is 100 (frame: 0~99)
NUIApplication.GetDefaultWindow().GetDefaultLayer().Add(myLottie);
myLottie.CurrentFrame = 200; //display 99 frame
myLottie.SetMinMaxFrame(10, 20);
myLottie.CurrentFrame = 15; //display 15 frame
myLottie.CurrentFrame = 50; //display 20 frame, because the MinMax is set (10,20) above

LoopCount

Sets or gets the loop count.

Declaration

public int LoopCount { get; set; }

Property Value

Type	Description
int

Remarks

The minus value means the infinite loop count.

Examples

LottieAnimationView myLottie = new LottieAnimationView();
myLottie.URL = Tizen.Applications.Application.Current.DirectoryInfo.Resource + "myLottie.json"; //myLottie.json's total frame is 100 (frame: 0~99)
NUIApplication.GetDefaultWindow().GetDefaultLayer().Add(myLottie);
myLottie.LoopCount = -1; //infinite loop
myLottie.Play();
myLottie.Stop(); //it plays continuously unless Stop() is called
myLottie.LoopCount = 2;
myLottie.Play(); //it plays only 2 times and stops automatically

LoopingMode

Sets or gets the looping mode of Lottie animation.

Declaration

public LottieAnimationView.LoopingModeType LoopingMode { get; set; }

Property Value

Type	Description
LottieAnimationView.LoopingModeType

PlayState

Gets the playing state

Declaration

public LottieAnimationView.PlayStateType PlayState { get; }

Property Value

Type	Description
LottieAnimationView.PlayStateType

StopBehavior

Sets or gets the stop behavior.

Declaration

public LottieAnimationView.StopBehaviorType StopBehavior { get; set; }

Property Value

Type	Description
LottieAnimationView.StopBehaviorType

TotalFrame

Get the number of total frames

Declaration

public int TotalFrame { get; }

Property Value

Type	Description
int

URL

Set or Get resource URL of Lottie file.

Declaration

public string URL { get; set; }

Property Value

Type	Description
string

Methods

GetContentInfo()

Get the list of layers' information such as the start frame and the end frame in the Lottie file.

Declaration

public List<Tuple<string, int, int>> GetContentInfo()

Returns

Declaration

public void Pause()

Play()

Declaration

SetMinMaxFrame(int, int)

Set the minimum and the maximum frame.

Declaration

public void SetMinMaxFrame(int minFrame, int maxFrame)

Parameters

Type	Name	Description
