Usage

Current stable version: 1.0

Gradle:

compile 'com.antonpotapov:poliwhirl:$version'

Maven:

<dependency>
    <groupId>com.antonpotapov</groupId>
    <artifactId>poliwhirl</artifactId>
    <version>$version</version>
</dependency>

In code:

You need to use only one class: Poliwhirl(). It's instance is reusable. So, you may create in only once. Also, there is no any long-time operations in instance creation, so you can create it each time you need it.

Async way

Poliwhirl().generateAsync(bitmap, object : Poliwhirl.Callback {
    override fun foundColor(color: Int) {
      // do whatever you need with the color
    }
})

Sync way

Poliwhirl().generate(bitmap);

Customizable way

Here you can provide an executor to poliwhirl. Poliwirl will try to execute it's calculation in parallel in this case. Also you can provide something like current-thread executor (thats how sync way is done) or whatever you need.

Poliwhirl().generateOnExecutor(bitmap, object : Poliwhirl.Callback {
    override fun foundColor(color: Int) {
        pictureBackground.setBackgroundColor(color)
    }
}, Executors.newSingleThreadExecutor())
