You don't even need the bounds. Just start from the smallest x,y to the
largest x,y at the appropriate step interval. You will have 1024 trace
lines per row for the pic. I am trying to find the mins/maxs for a HL1
map to post the calcs for you, but I am unable to find the dims right now..

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.
