Thanks for the comment. There are many ways to enjoy Sunday afternoon. Others spend hours turning up their processors, others scrape up the tiktok and yet others gather as much knowledge as they can about losslessness in the digital world. As I mentioned at the beginning, there is no single place on the Internet (post) that would specifically tell how to approach visual compression without loss, nor is there one that offers some tests. The concepts of “loss, loss, coding, bits, open source” are the basic knowledge which “needs” to understand further information. You don’t take medicine unless you know the basics of biology. Anyway, this is the development that there is a person who collects knowledge and data from various sources, draws conclusions and makes them available so that another person can feed on them for their research. I hope you understand ;) Greetings.
