How do the Map.db files work?

[CoZzaBoZza]

Just to start, I don't have any real experience programming or anything, but I want to create a mod that can export my map as a PNG for the sake of being able to plan out my worlds eventual layout and such. I have gotten completely stuck on decompiling the SQL databases.

This is way over my head so I can't be of any help, but you could look how https://mods.vintagestory.at/vsdbtopng solves this.

I made you a lil' drawing. 
You might also want to take a look at :

• https://github.com/elliotfontaine/vsmaptools/blob/v2.1.0/classes/map_piece.gd (for how I do it)
• https://wiki.vintagestory.at/index.php/Modding:Deserializing_protobufs_from_the_command_line
• https://github.com/bluelightning32/vs-proto/blob/80ff05afa98af324425ef6f3e5f12b4bea9e6a3f/schema-1.21.0.rc.3.proto#L72C1-L74C2

Feel like I just asked a question on that 'Explain to me like i'm 5' page on reddit, and I couldn't be happier with the response 

You're a legend mate.

TBH, your mod for this is better than anything I was going to make, might end up just using it lol. This will make for a good side project to practice C# a bit tho
