I'm using this Mathematica snippet to generate tie breaker tracks based on the given tie-breaker. I sometimes need to add or remove a few more rows/columns to/from the boundary to ensure square sizes. Otherwise the track is used as is.

ppcg-vr-tie-breaker-generator

res = 290;
Riffle[
  (*remove road cells around the border*)
  (Drop[#, 4]) & /@ (Drop[#, -4] &) /@ Most@Rest@
       ImageData[
        Binarize@Rasterize[
          Import["path\\to\\tie-breaker.pdf"],
          ImageSize -> res + 8
          ]
        ] /. {0 -> "#", 1 -> "."},
  "\n"] <> ""
