Bindings to image-rs for APNG support on Android.
You can include the decoder with
implementation("me.tatarka.android:apngrs:0.4")Then you can create a source and decode a drawable. The api is mirrored after ImageDecoder.
val source = ApngDecoder.source(resources, R.drawable.my_animated_png)
val drawable = ApngDecoder.decodeDrawable(source)
drawable.start() // to start the animation.For easy coil integration, include
implementation("me.tatarka.android:apngrs-coil:0.4")and then add the decoder
val imageLoader = ImageLoader.Builder(context)
.components {
add(ApngDecoderDecoder.Factory())
}
.build()- All animations are currently rendered as looping infinitely instead of respecting the num_plays value.
- Image data is loaded first into a byte array in memory before decoding, could do some sort of streaming support here if I could figure out the jni bits for that.
- image-rs actually supports a wide range of image formats but only APNGs are currently supported. May be expanded in the future if there's value.
- Source inputs are limited to byte arrays and resources, this could be expanded pretty easily.
