When you input boundaries, mcmap
will intersect your boundaries with the available map and render that.
This line: [Debug] Processed boundaries: 2147483647.2147483647.-64 ~> -2147483648.-2147483648.319 (North-West)
means that the intersected coordinates are undefined; maybe your world is empty, maybe you put the wrong dimension; either way, it did not find terrain to render.
The whole argument parsing needs to be remade. This is confusing and misleading.
To make sure, look at the output of ls [path-to-world]/region
(for the overworld).

Thanks for this, turns out it was my fault and I was just executing the command with the wrong world directory...

I cannot figure out how you managed to do this. I was trying to create a fix, but I cannot reproduce this issue. When you generate a new world, it automatically generates some spawn chunks. If you close minecraft too early, or something else weird, it doesn't create and level.dat
files, and there are logical error messages already built in for this.

Can you give some instructions on how to reproduce this error?
from mcmap.
This error arises when the requested area does not overlap with the available terrain. Try rendering a new world with the -from -5000 -5000 -to -4990 -4990
options (the values do not really matter).
mcmap
calculates the intersection of what is requested and what is available. When this is an empty area, the area has its coordinates set to special values, and this is not checked in the argument parsing code. Those values are the integer boundaries (minX/Z to the maximum possible value, maxX/Z to the minimum). This triggers the error that you see.
The whole argument parsing code is legacy from the start of the project. One needs to take it all down and use a modern c++ library to parse the command line.

probably too far out of my comfort zone then. I'll leave this for someone better with C++
