Looks like maps range +-4096. So if you create and image that is
1024x768. You would:
1) Trace from x = -4096 to x = +4096 at (4096/1024=4) point intervals.
2) Trace from y= -4096 to y= +4096 at (4096/768=5.33) point intervals.
Each picture would require 786,432 (1024*768) trace lines. It might take
a little bit of time, but it is simple and would work for any map.

How do you grab the bounds of the map?

What's tricky? Seems you can just grab the bounds of the map(very
trivial)
and double for loop through the 2 horizontal coordinates, doing
tracelines
at whatever interval is suitable for the resulting resolution you
intend to
use.
