# ApngDrawable

[![Maven Central](https://img.shields.io/maven-central/v/com.linecorp/apng)](https://search.maven.org/artifact/com.linecorp/apng)

ApngDrawable is fast and light weight Animated Portable Network Graphics(APNG) image decoder library for Android platform.
ApngDrawable is written in Kotlin and C++.

## How to use

Use Gradle to build the library. Download it from [Maven Central](https://search.maven.org/artifact/com.linecorp/apng) and add configurations in the `build.gradle` file as follows.

```build.gradle
// In your top-level project's `build.gradle`
allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

// In your app project's `build.gradle`
dependencies {
  implementation 'com.linecorp:apng:x.y.z'
}
```

If using Kotlin Gradle DSL, add configurations in the `build.gradle.kts` file as follows.

```build.gradle.kts
// In your top-level project's `build.gradle.kts`
allprojects {
    repositories {
        mavenCentral()
    }
}

// In your app project's `build.gradle.kts`
dependencies {
  implementation("com.linecorp:apng:x.y.z")
}
```

## Getting started

You can decode from a lot of source types, e.g. File, InputStream and Resources.

```kotlin
// Decode from File
val drawable1 = ApngDrawable.decode(File("path/to/file"))

// Decode from InputStream
val drawable2 = File("path/to/file").inputStream().use {
    ApngDrawable.decode(it)
}

// Decode from Resources
val drawable3 = ApngDrawable.decode(context.resources, R.raw.apng_image)
```

You can find a more advanced way of using the library from the [example](https://github.com/line/apng-drawable/tree/master/sample-app).

## How to build

Note: This operation is necessary when building from code. It's not necessary if you are reading using `implementation` as shown in "[How to use]".

The patched `libpng` sources aren't included in the repository.
You need to download `libpng` and apply APNG patch first.

```sh
$ cat libpng_version | xargs ./download_libpng_and_apply_apng_patch.sh
$ ./gradlew :sample-app:assembleDebug
```
