Hi,
I created a map using specific x/y positions, but the map image created is all of the explored area. I have used the app in the past and it worked well.
edit: I tested on smaller maps, and it works fine. But on my large, Earth map, generated 6G of data across 700k files. It looks great, but it is more than I wanted - and I can't upload it to my hosting site. (It took a couple of hours to generate.)
edit2: I am using FactorioWorld, which is an Earth map with a pre-set base map, which may be doing weird things with the locations / coordinates.
thanks,
jon
