Usage

# show help and usage
./maprenderer -help

Isometric map

./maprenderer -world /home/user/.minetest/worlds/myworld/ -from -200,-50,-200 -to 200,100,200 -type isometric

Example output:

Flat map

./maprenderer -world /home/user/.minetest/worlds/myworld/ -from -200,-50,-200 -to 200,100,200 -type map
