29 5) Open the file in Inkscape again, Click on the path again, then go to Extensions->Modify Path->Flatten Beziers and flatten out the curves to your taste. Default of 10 seems fine most of the time, but for small curved objects you might want something like 5. Keep in mind, the more the approximation, the more points that Hedgewars has to draw, which can be rough on the engine and network communication, then save and quit. |

31 6) Edit the file, and delete everything but the path data. You should have a one-line file starting with something like M1234.3 456.78L3298.3 9023.34 and so on. |

32 If instead you have a format like M 1234.678,9875.323 2345.0,123.45 - you'll want to convert if you want to try the crude script in (10) - otherwise a smarter script would be needed. Here's some Vim commands for that syntax {{{s/\(\d\) \(\d\)/\1 L\2/g}}} and {{{s/,/ /g}}} and {{{s/\([LM]\)\s*/\1/g}}} |

37 Also, it is probably a good idea to remove duplicate points. Here's a regex for that. {{{s/\(L\d\+ \d\+ \)\1/\1/g}}} - you should run that a couple of times, then {{{s/M\(\d\+ \d\+ \)L\1/M\1/g}}}. That just cuts down on a bit of redundancy. If these regexes match anything, you probably should rerun them. |
