quicoli / lottiesharp Goto Github PK

I'm considering using LottieSharp in a .NET Framework / WPF application. LottieSharp depends on SharpDX which does not seem to be maintained anymore (see https://github.com/sharpdx/SharpDX). Are there any plans to address this in the future?

Kind Regards
Daniel

I need to use a json to make a gif , and when i put the control in my page the error " Object reference not set to an instance of an object" appears , my json is ok i have tried it like embedded resources and also content and it's not working, I don't know how to solve this please

Describe the bug
Switching between views application crashes. Sometimes it takes just to go to another view to make app crash. The error is from SharpDX.

SharpDX.SharpDXException: 'HRESULT: [0x88990012], Module: [SharpDX.Direct2D1], ApiCode: [D2DERR_WRONG_FACTORY/WrongFactory], Message: Objects used together must be created from the same factory instance.

To Reproduce

1. Load app (when animation starts)
2. Go to another view (closes main view)
3. Open main view again.
4. BAM! Crash!

Expected behavior
Animation should not make app crash and after returning to main view I should see working animation again.

Hi,
I would like to use Lottie with .Net version 4.6.
Is there a specific reason why you are targetting .Net 4.6.1 or can I just compile using 4.6?

Button Click Event Handler

  private void Button_Click(object sender, RoutedEventArgs e)
        {
            //lottieAnimation.StopAnimation();
            lottieAnimation.PlayAnimation();
        }

To Reproduce
Steps to reproduce the behavior:

1. Click on the button
2. Animation plays
3. Click again on the button
4. Nothing happens

Uncommenting StopAnimation makes no difference.

Expected behavior
Every time I click the button the animation should play

It would be possible to add a reverse animation. Here is an example animation.

Thanks a lot.

Is your feature request related to a problem? Please describe.
In the Airbnb version you can change the colours that are in the animation, it would be great if we could do it through code and not have to edit the json file for the new colour

Describe the solution you'd like
Some way to change the colours of the animation in code and not with editing the json file

Describe alternatives you've considered
editing colour in json file before loading animation (how I'm doing it right now)

When using this nuget withing strongly named assembly project it generates warning that LottieSharp assembly does not have strong name.

It would be good, if the exception would be handled more gracefully. Unfortunately this has been only reported to me, so I cannot reproduce it by myself.

Bug
I've recently downloaded several lottie files for testing purposes from lottiefiles.com and they can't be made to run. LottieSharp produces crashes likes "Keyframes are missing". The old test-downloads is used work fine. There is a version descriptor in the lottie files ("v":"5.1.12"), the new files have versions like "5.8". I guess there have been changes in the JSON file structures?

Reproduce
Take a lottie file from https://lottiefiles.com/12672-letter?lang=de, download it and load it. As soon as the rendering starts the .net app crashes.

Expected behavior
The file should load and render.

Environment
Windows 10, VS 2017, VB# Windows application

Describe the bug

Hello guys,

this weekend I found this:

Codegen post about generating c# classes based on lottie animations....

What do you think of this? Would be worthy to have something like this for LottieSharp?

Windows in version 1.1.2 drag form slowly

Regards

Is your feature request related to a problem? Please describe.
I use the LottieAnimationView inside canvases together with other shapes. My test-lottie's are rendered with white background which overlaps shapes. I would be beneficial if there would be an option inside LottieSharp to render the shapes with transparent background. I know there are SharpDX options for that, but I don't know nothing about SharpDX in detail.

Describe the solution you'd like
Background is not white but transparent.

Describe alternatives you've considered
I tried to set "background" to "000" for the LottieAnimationView, but that had no effect. There are notes about "how to set sharpdx background to transparent" by setting the background and the backgroundcolor to "#00000000" but this didn't seemed to work.

Additional context
I'm willing to contribute if someone would give me an pointer where to add it.

Describe the bug
I am trying to use this library to display telegram stickers, but I always get a NullReferenceException ("Unable to parse composition"). So, I downloaded this repo and I was able to reproduce this issue in the Sample-Project.
Unzipping my tgs-files also works properly, I've also tested the result json in https://lottiefiles.com/tools/json-editor and it's working.

Sample-JSON-File:
1137162165791228122.tgs.zip

So, while debugging I figured out that animatableTransform.Rotation is null:
https://github.com/ascora/LottieSharp/blob/80d9cf27ccd234d2b23c523f1ad2b0ea2432f07c/LottieSharp/Animation/Keyframe/TransformKeyframeAnimation.cs#L29

As a result I added null-checks in TransformKeyframeAnimation where _rotation is used and it works fine.

Hellow Is this project funcional in WPF or is only a fake delution?

I have tried running the LottiSharp.Sample and this exception is the only thing that i get back from the app.

Tried playing all of the asset animations in the sample, but none of them do anything, also tried my own animation (did not work either). I have also tried using the library in my own project with the same result.

I am running NET 5 version on windows 10 (if that can be related).

Anybody knows what this could be? Thank you very much!

When using a lottie animation using LottieSharp v2, I'm getting a low framerate playback, maybe 15fps or so. If i use the exact same Json file in winui 3 the playback is a smooth 30fps. Is there anything I'm doing wrong here?

Steps to reproduce the behavior:

• New WPF app
• Download https://assets4.lottiefiles.com/packages/lf20_b88nh30c.json
• Add LottieAnimationView and point to downloaded json file.

Expected behavior
Smooth playback

Screenshots
WPF (60 FPS GIF)

WinUI 3 (60 FPS GIF)

Nice plugin for Windows Form applications.

I'm not sure if this feature already exists, but it would be nice to get a event when the animation is finished.

Can the ZIP package containing the image file be used? Set FileName=ZIP path directly and set FileName=JSON path path after decompression.

The sample in design mode was raising an exception in Visual Studio designer, blocking the view of the mainwindow xaml. To fix, change the LottieAnimationView.LottieAnimationView() to this:

    public LottieAnimationView()
    {
        _lottieDrawable = new LottieDrawable();

        if (!DesignerProperties.GetIsInDesignMode(this))
        {
            if (!string.IsNullOrEmpty(FileName))
            {
                SetAnimationAsync(FileName).RunSynchronously();
            }
            else if (!string.IsNullOrEmpty(Url))
            {
                SetAnimationFromUrlAsync(Url).RunSynchronously();
            }

            if (AutoPlay)
            {
                _lottieDrawable.PlayAnimation();
            }
        }

        _lottieDrawable.RepeatCount = RepeatCount;

        EnableMergePathsForKitKatAndAbove(false);

        SimpleColorFilter filter = new SimpleColorFilter(ColorFilter);
        KeyPath keyPath = new KeyPath("**");
        var callback = new LottieValueCallback<ColorFilter>(filter);
        AddValueCallback(keyPath, LottieProperty.ColorFilter, callback);

        EnableOrDisableHardwareLayer();
    }

I just moved the "if (AutoPlay") to be executed only if not in design mode.

BTW, do you have tasks for this project? I'd like to help you.

Hello,

after using this plugin in a WPF project, we saw that texts elements of the Lottie json file are shifted to the right, compare to the real animation.

For exemple, we have this animation that "Lottie" text appeared at the bottom right corner.

When this JSON is used with LottieSharp, there is the same animated frame but the text "Lottie" is shift to right, as we can see in the picture below representing the last frame of the animation.

There is a solution to this ? Or this a bug to fix ?

Thanks in advance for your time

I have a short question:
Is it possible to enable animation in case of Remote Desktop Connection is used?
Actually I see animations only in case of native Windows Session, but not over a RDP Session.

Describe the bug
I try to set the FileName property if the file does not exist, I got an exception.

Using this sample-file leads to an ArgumentOutOfRangeException here
https://github.com/ascora/LottieSharp/blob/80d9cf27ccd234d2b23c523f1ad2b0ea2432f07c/LottieSharp/Model/Content/ShapeData.cs#L68

I don't know exactly why the curves don't have the same amount of points, but this json file also works at https://lottiefiles.com/tools/json-editor.

As a fix I changed the line to:

for (var i = Math.Min(Math.Min(shapeData1.Curves.Count, shapeData2.Curves.Count), _curves.Count) - 1; i >= 0; i--)

But I don't really know if this is the correct solution to fix this problem, but at least this prevents the App from crashing and the output looks fine though.

The issue is when window with animation opened, then ctrl+alt+del is clicked and animation disappears.

Steps to reproduce the behavior:

1. Load animation
2. Click ctrl+alt+del or window button+L
3. Go back to your animated window.
4. Bam! The animation is gone.

I added a a json file from the stock lottie animations on their website. On running the application, the app was consuming a total of 70MB memory. Within a minute, it shooted to 100MB.

To Reproduce
Steps to reproduce the behavior:

1. Create a new project and Install the package via nuget.
2. Extract and add the following to your bin/Assets folder.

phone_number_verification.zip

3. Add this to MainWindow.xaml

3. Run the app
4. Open Resource Monitor and check the memory of your app being increased gradually.

My company is using LottieSharp to display JSON videos in our application via the WPF LottieAnimationView. We are just setting a file name and setting AutoPlay=true. When I run a test program that just displays the video second window, the Unmanaged memory goes up by 8 MB each time the video is run.

We do automation testing on our application and since we have added LottieSharp videos, the automation testing fails quickly with out of memory exceptions.

The leaks appear to be in the SharpDX library.

Is anyone else seeing these?

Expected behavior
No unmanaged memory leaks.

Hi folks,

I will have lotties files stored within a database, so I can't use the filename property. I would like to have something like a content property which can be set from code behind.

Any plans on this?

If not, I'm willing to implement it and share...

Describe the bug
The LottieView is not support the pack uri like "pack://siteoforigin,,,/Resources/Lottie/xxx.json".I got blank by this way.
To Reproduce
Steps to reproduce the behavior:

1. Load the lottieview
2. The lottieview show blank window

Is your feature request related to a problem? Please describe.
I don't want to expose json file on to the user's files system.

Describe the solution you'd like
Would be good if the library could support reading the json from app's resource i.e. pack URI.

Describe alternatives you've considered
The other way is to write additional code to read json from resource and pass it to the library.

@Crayjin How do you think about this logo?

Trying to load this animation:
https://lottiefiles.com/5901-gradient-loading-icon

Got this exception when the application starts:
System.InvalidOperationException: 'Missing values for keyframe.'

From what I could understand, the issue relates to newer versions of Lottie files.

Please advise...
