Common problems that may arise when using mangle:
- Mangle won't compile
- Did you remember to run snap on your input polygon files?
- Multiply-intersecting and kissing circles
- A routine complains of `total failure' or some other fatal error
- balkanize is making unexpectedly vast numbers of polygons
- Some of the polygons that come from my vertices file are 180° away from where they should be
- Some of the polygons that come from my edges file are not right – the polygon does not even pass through the points!
- How can I get rid of all the tiny polygons?
- How can I get rid of all the polygons with zero weight?
- When I output to graphics (or vertices, or edges) format, it tells me that some of the polygons of my balkanized mask have multiple boundaries
- Your fortran refuses to read the unformatted fortran files made on another system
- Is there a simple way to determine the area of a mask?
- How to define a polygon which is the entire sky?
- How to make the complement of a mask?
- Is there a way to harmonize the complement of a mask directly from the holes?
If you have diligently read and attempted all of the solutions presented here, and your problem still occurs, either you may have a very complicated polygon (like a fractal) or you may have found a genuine bug in mangle. If you suspect it is a bug, please email the mangle development team the following information:
- The input polygon files that give the problem;
- The sequence of commands that give the problem;
- The output of the sequence of commands (with verbose on, i.e. without the -q quiet flag).
