#9168: polygon resize -1 of a 1 point wide polygon doesn't make it disappear
------------------------------+----------------------
Reporter: Stefan Thiede | Owner: ljsimons
Type: Bugs | Status: new
Milestone: To Be Determined | Component: polygon
Version: Boost 1.54.0 | Severity: Problem
Keywords: polygon resize |
------------------------------+----------------------
I tried to use resize(pset, -1); resize(pset, 1) to filter the results of
a xor which should remove all polygon with only 1 or 2 database unit
differences.
resize -1 generates wrong output if the polygon are not orthogonal.
input: 0,0 0,5 1,5 1,0 3,-3
resize -1: 0,1 -3,5 0,0 0,1
