More about this library

Because I couldn't find a free implementation of .NET Core HTML to Image library, I've developed my own and hope it will help other people as well. This library wraps very nice wkhtmltoimage tool (https://wkhtmltopdf.org/). I have wkhtmltoimage.exe embedded into my library. This is a very simple implementation. Your contributions are very welcome!
