This library was forked from: https:/deanveloper/SkullCreator. With the intention to improve its performance where possible and add support to more versions starting at 1.8.
Supported versions: 1.8 (might work on 1.7, haven't tested yet) and newer. The current version was only tested on the versions: 1.8, 1.12 and 1.18.1. If you want to help, fell free to test it on more versions. PRs are welcome.
If you want a gist of how the library works, you can find an example in the examples' folder, which should help you get started...
To use this library, you can either copy the source code from repo and put it in your project, or you can get it through JitPack. Head out to https://jitpack.io/#alisson0022/SkullCreator to see some tutorials.
And here are some website that will provide texture URLs and base64 encoded strings for you to use with the library: freshcoal, mineskin, minecraft-heads.
