Can I use your library to check the source is APNG or not?

如何停止播放后，停留在第一帧呢？

I am using your library with my application and I am pretty happy with it. Recently, FDroid build failed due to the dependency to https://dl.bintray.com/osborn/Android
What would be the best way to remove this dependency? Thanks for helping

I am using this library. And it is very cool compared to others...

However, the ratio seems fixed. is there any way to change it into match_parent/match_parent?

The error is handled in APNGFrame.java

Would it be possible to stop the animation especially for the FileNotFoundException

Currently it's possible to use ResourceStreamLoader from a drawable:

// Load form Resource
ResourceStreamLoader resourceLoader = new ResourceStreamLoader(context, R.drawable.sample);

Would it be possible to use it with any drawable?

The idea is to use the lib with Glide without the plugin:

 Glide.with(context)
                        .asDrawable()
                        .load(emoji.getUrl())
                       
                        .into(new SimpleTarget<Drawable>() {
                            @Override
                            public void onResourceReady(@NonNull Drawable resource, @Nullable Transition<? super Drawable> transition) {
                                ResourceStreamLoader resourceLoader = new ResourceStreamLoader(context, resource);
                            }
                        });

Currently I use File instead of Drawable to make it work with Glide.

相同的apng链接 下拉刷新重复加载后 apng播放速度越来越快

这边遇到了一种情况
有时FrameAnimationDrawable的onRender方法调用时frameSeqDecoder.getSampleSize()返回的是1
接着frameSeqDecoder的setDesiredSize调用，然后sampleSize就变成2了
再往后的onRender方法里，给过来的byteBuffer就小了，但是bitmap已经创建了，还是原来的大小所以
if (byteBuffer.remaining() < this.bitmap.getByteCount()) {
Log.e(TAG, "onRender:Buffer not large enough for pixels");
return;
}
这个条件就一直是true了，就一直报这个错误了

I have an issue with animated emoji in a GridView using ArrayAdapter. It's lagging and I got a lot of messages: E/FrameSeqDecoder: Processing,wait for finish at INITIALIZING

Here is my adapter:

public class CustomEmojiAdapter extends ArrayAdapter<Emojis> {


    private Context context;
    private List<Emojis> emojis;

    public CustomEmojiAdapter(@NonNull Context context, int resource, List<Emojis> emojis) {
        super(context, resource, resource);
        this.context = context;
        this.emojis = emojis;
    }

    @Override
    public int getCount() {
        return emojis.size();
    }

    @Override
    public Emojis getItem(int position) {
        return emojis.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @NonNull
    public View getView(final int position, View convertView, @NonNull ViewGroup parent) {
        final ImageView imageView;
        Emojis emoji = emojis.get(position);
        if (convertView == null) {
            LayoutInflater layoutInflater = LayoutInflater.from(context);
            convertView = layoutInflater.inflate(R.layout.drawer_emoji_picker, parent, false);
            imageView = convertView.findViewById(R.id.img_custom_emoji);
        } else {
            imageView = (ImageView) convertView;
        }

        SharedPreferences sharedpreferences = context.getSharedPreferences(Helper.APP_PREFS, Context.MODE_PRIVATE);
        boolean disableAnimatedEmoji = sharedpreferences.getBoolean(Helper.SET_DISABLE_ANIMATED_EMOJI, false);

        Glide.with(context)

                .load(emoji.getUrl())
                .listener(new RequestListener<File>()  {

                    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target target, boolean isFirstResource) {
                        return false;

                })
                .into(new SimpleTarget<File>() {
                    @Override
                    public void onResourceReady(@NonNull File resourceFile, @Nullable Transition<? super File> transition) {
                        Drawable resource;
                        if(GifParser.isGif(resourceFile.getAbsolutePath())){
                            resource = GifDrawable.fromFile(resourceFile.getAbsolutePath());
                        }else{
                            resource = APNGDrawable.fromFile(resourceFile.getAbsolutePath());
                        }

                        if( !disableAnimatedEmoji) {
                            resource.setVisible(true, true);
                            imageView.setImageDrawable(resource);

                        }else{
                            Bitmap bitmap = drawableToBitmap(resource.getCurrent());
                            imageView.setImageBitmap(bitmap);
                        }
                    }
                });
        return convertView;
    }

}

I can't use the plugin for Glide but it worked perfectly simply with:

 Glide.with(context)
                .load(emoji.getUrl())
                .into(imageView);

加载网络apng动画资源只显示静态图不能播放动画，加载本地资源没有问题

Issue Info

Loading APNG doesn't show an animated image.

Trying to load APNG into an ImageView using the following code

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        Glide

            .load("https://misc.aotu.io/ONE-SUNDAY/SteamEngine.png")
            .into(img)
    }
}

With the following dependencies

implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'
implementation 'com.github.penfeizhou.android.animation:glide-plugin:2.0.0'

Image is loaded but it is not moving, I tried the one with WebP https://isparta.github.io/compare-webp/image/gif_webp/webp/2.webp and it is working perfectly.

Device tested on:
Emulator: Nexus 5 API 28
minSdkVersion: 26
targetSdkVersion: 30

Also used this Image, still same result

I would be happy to support more info

Any idea why is this happening?

Glide.with(imageView)
    .load("https://misc.aotu.io/ONE-SUNDAY/SteamEngine.png")

question

How can I register the Animatable2Compat.AnimationCallback to Glide?
I want to get the callback on animation start and end.

I implemented a function that allows to load GIF if requested but when scrolling down, I have a lot of messages : E/FrameSeqDecoder: Processing,wait for finish at FINISHING and the app freezes.
I simply use that method:

public static void loadGiF(final Context context, String url, final ImageView imageView){
        SharedPreferences sharedpreferences = context.getSharedPreferences(Helper.APP_PREFS, Context.MODE_PRIVATE);
        boolean disableGif = sharedpreferences.getBoolean(SET_DISABLE_GIF, false);
        Glide.with(imageView.getContext())
                .asDrawable()
                .thumbnail(0.1f)
                .load(url)
                .into(new SimpleTarget<Drawable>() {
                    @Override
                    public void onResourceReady(@NonNull Drawable resource, @Nullable Transition<? super Drawable> transition) {
                        if( !disableGif) {
                            resource.setVisible(true, true);
                            imageView.setImageDrawable(resource);
                        }else{
                            resource.setVisible(true, true);
                            Bitmap bitmap = drawableToBitmap(resource.getCurrent());
                            imageView.setImageBitmap(bitmap);
                        }
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                            imageView.setClipToOutline(true);

                        imageView.setBackgroundResource(R.drawable.rounded_corner_10);
                    }

How does it happen？

我看了一下最近1.3.3 change log，增加了一条 Avoid buffer size smaller than the target bitmap。
想确认一下这个是在什么情况下出现的，因为修复的代码只是做了一个防止错误的出现而已，是否彻底解决了问题？

Issue Info

public static final Option<Boolean> DISABLE_ANIMATION_GIF_DECODER = Option.memory( "com.github.penfeizhou.animation.glide.AnimationDecoderOption.DISABLE_ANIMATION_GIF_DECODER", false);
注释里面默认值是true，但是代码里面是false
现在使用glide加载图片，得到的GifDrawable是这个库的，不是glide默认的。

Issue Description and Steps

When trying to use the library's FileLoader, my images wouldn't be displayed when passing absolute paths located on the SD card. I guess that is because APNG4Android relies on File only, and not on SAF.

To fix that, I implemented a custom StreamLoader that fetches the proper InputStream (see below).

The problem is, APNG4Android seems to call InputStream's reset method without intercepting the IOException, resulting in an empty image.

NB : The problem does not come from the test image I use, because it is properly displayed and animated when located in the phone's memory (the area where new FileInputStream(file) works fine).

//                FileLoader loader = new FileLoader(absolutePath):  <-- doesn't work when absolutePath points to a location on the SD card
ImgLoader loader = new ImgLoader(absolutePath);
APNGDrawable apngDrawable = new APNGDrawable(loader);
imgView.setImageDrawable(apngDrawable);

// Load the image using an InputStream whatever the location of the path (phone memory or SD card)
static class ImgLoader extends StreamLoader {

        private String path;

        ImgLoader(String path) {
            this.path= path;
        }

        @Override
        protected InputStream getInputStream() throws IOException {
            DocumentFile file = FileHelper.getDocumentFile(new File(path), false); // Helper to get a DocumentFile out of the given File
            if (null == file || !file.exists()) return null; // Not triggered

            return App.getInstance().getContentResolver().openInputStream(file.getUri());
        }
    }

Suggestions
a. Catch the reported exception (see below) and continue loading the image properly
and/or
b. Use ContentResolver.openInputStream inside FileReader to support resources located on SAF area.

hi,
I'm using APNG4Android source code with Glide, when testing ,apng and gif get nothing wrong, but webP seems to have some rendering problem.

• When some webP image playing, i can see white rectangle area with some colorful pixels on it. Seems like something wrong with blending.
• And some other webP image playing faster than the speed it playing on webpage.

Hope you can help me! Thanks.

• webP image with white rect url:
  https://misc.aotu.io/ONE-SUNDAY/world_cup_2014_42.webp
  https://misc.aotu.io/ONE-SUNDAY/BladeRunner.webp
• webP image running fast url:

Hey,
I wonder if the library could accept a lower minSdkVersion currently set to 19?

Hello!
I saw your library and I really like it.
It is the only library I found that handles animated webp, but unfortunately I couldn't make it work.

I tried both:

final byte[] ret = WebPEncoder.fromGif(new AssetStreamLoader(context, "test.gif")).build();
File file = new File(context.getCacheDir(), "test.webp");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(file);
fos.write(ret);
fos.flush();
fos.close();
} catch (Exception e) {
e.printStackTrace();
}

and

WebPEncoder encoder = new WebPEncoder();

int duration = 0;
for (int i = 0; i < standardGifDecoder.getFrameCount(); i++) {
Bitmap bitmap = standardGifDecoder.getNextFrame();
encoder.addFrame(bitmap, 0,0, standardGifDecoder.getNextDelay());
}

But both gave me an invalid webp file (attaching it).
test1.zip

The original gif:

It would be amazing if you could help me, or even direct me to the bug so I can open a PR.
Thanks!

I'd like to process something when it's specific index.

I try to use APNG4Android with Glide and ImageSpan for displaying animated png like this one

Animated emoji

As soon as I import the lib 'com.github.pengfeizhou.android.animation:glide-plugin:0.2.16', drawable are no longer displayed. I use this code:

  Glide.with(context)
	.asDrawable()
	.load(emoji.getUrl())
        .into(new SimpleTarget<Drawable>() {
        	@Override
                public void onResourceReady(@NonNull Drawable resource, @Nullable Transition<? super Drawable> transition) {
 			resource.setBounds(0,0,(int) Helper.convertDpToPixel(20, context),(int) Helper.convertDpToPixel(20, context));
                        ImageSpan imageSpan = new ImageSpan(resource, ImageSpan.ALIGN_BASELINE);
                        contentSpan.setSpan(imageSpan, startPosition,endPosition, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
		}
  	});

I don't get errors so I guess I am not using it correctly.

irrelevant

调用代码如下：
Glide.with(this)
.load("$rootDir/animPic/microphone.png")
.listener(object : RequestListener {
override fun onLoadFailed(e: GlideException?, model: Any?, target: Target?, isFirstResource: Boolean): Boolean {
return false
}

                override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean): Boolean {
                    if (resource is APNGDrawable) {
                        resource.setLoopLimit(0)
                    }
                    return false
                }

            })
            .into(ivMicrophone)

线上出现大量：

我是使用OKhttp下载到本地后，使用此框架加载的。

1.很感谢你的库。
2.使用FileLoader加载apng文件，出现内存以0.2M/s的速度在增加，然后加载到一定大小又回回到原内存，请问这种情况是什么原因？是否正常？

Issue Description and Steps

I can't reproduce that on my end but I got several reports.

Does the Glide support change the general behaviour (or is it a change in Glide 4.9.0)? I will explain my issue.

I was using Glide in that way for loading some profile pictures:

 Glide.with(imageView.getContext())
                        .load(url)
                        .apply(new RequestOptions().transforms(new CenterCrop(), new RoundedCorners(10)))
                        .into(imageView);

When it was a gif URL, that worked but now I get a message telling me it can't load a gif image as a bitmap.

My current fix is:

 if ( url.endsWith(".gif")) {
            try {
                Glide.with(imageView.getContext())
                        .asGif()
                        .load(url)
                        .apply(new RequestOptions().transforms(new CenterCrop(), new RoundedCorners(10)))
                        .into(imageView);
            } catch (Exception ignored) {
            }
        } else {
            try {
                Glide.with(context)
                        .asBitmap()
                        .apply(new RequestOptions().transforms(new CenterCrop(), new RoundedCorners(10)))
                        .load(urlStatic)
                        .into(imageView);
            } catch (Exception ignored) {
            }
        }
