WebMay 13, 2024 · I need to offset edges of a polygon by different amounts. buffer() will parallel-offset all the edges by the same amount, and each in its edge-normal direction (and in both directions if applied to a LineString). parallel_offset() will offset a whole LineString by the same amount, but that means that if given only some edges of a polygon, the result is … WebThis is called polygon offsetting rather than scaling. In the general case, this is much harder than it seems, as different parts of the inflated polygon can overlap each other, letting holes appear, and some edges may completely disappear. The way to handle corners isn't so well defined either. For an exact solution, have a look at Clipper.
