IridescentView

A custom View for Android Java / Xamarin.Android that creates an iridescent effect on top of images.

The IridescentView is a custom ImageView that applies an iridescent effect on images, according to the device's rotation. The rotation is acquired by the accelerometer and used for the calculation of the effect.

The component is available for Android Java and Xamarin.Android.

To use in Android Java

In the Gradle scripts, the Maven Central repository must be declared:

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        // other Maven repositories
    }
}

In the Gradle script of the module in which you want to use the View, include the dependency inside the dependencies block:
