Channel Extraction 1. Images are used throughout different applications. 2. We want to extract color channels that images consist of. 3. We want to provide a service with communication endpoint.Implementation:

Channels provide another way to have different variants of packages for the same library and use them interchangeably to bintray. You can manage it as a package, you can version it, overwrite it, delete it, create channels (testing/stable...), and the most important: bring it to your projects as a regular dependency. built and tested in a wide range of configurations). From the perspective of a library developer, channels could be used to create different scopes of your library. For example, use rc channel for release
