    QOI

    QOI

    The “Quite OK Image Format” for fast, lossless image compression

    QOI, short for “Quite OK Image,” is a minimalist lossless image compression format designed to achieve extremely fast encoding and decoding speeds while maintaining compression ratios comparable to PNG. The project was created as a simpler alternative to complex legacy image formats, using an intentionally lightweight specification that can be implemented in only a few hundred lines of code. QOI focuses on predictable O(n) performance and efficient pixel encoding strategies without relying on heavyweight compression algorithms like DEFLATE. The format supports RGB and RGBA images while remaining easy to port across programming languages and hardware environments. ...

You can learn more read the installation doc. When you environment will be ready, and you can start using SchemaSpy you can read more about the configuration. Browse some sample pages generated by SchemaSpy. Note that this was run against an extremely limited schema so it doesn't show the full power of the tool.
