Can't generate map on large maps

[jahands]

On large maps it only creates a single zoom level. The index.html shows this:

CustomMapType.prototype.minZoom = 2;
CustomMapType.prototype.maxZoom = 2;

Any way to fix this?

I saw there was a thread that it happens when using coordinates >4096

Here is a map where this is an issue: https://dl.jha.sh/github/2018/06/05/kxb9b/FactorioMMO-Reddit-June-Community-Map.zip

Looks like this fixes it: local resolutionArray = {8,16,32,64,128,256,512,1024,2048,4096,8192,16384,32768} on https://github.com/credomane/FactorioMods_FactorioMaps/blob/master/fm/generateMap.lua#L25

FYI - despite this change I can only generate maps up to 8192x8192 before it crashes (after hitting like 20GB of RAM).

Okay I figured out a solution to it crashing. For large maps, I add a check to only generate screenshots if z is > minZoomLevel like so:

    for z = minZoomLevel, maxZoomLevel, 1 do  -- max and min zoomlevels
        if z >= minZoomLevel+1 then -- add +X for larger maps
            for y = 0, numVScreenshots - 1 do

The game is not entirely consistent on when you need to do this. Usually 8192x8192 maps seem to be fine without this, but on some maps I've found much smaller maps have issues too.
