The input vertices are {{{ (4000, 0) (2500, 500) (0, 3000) (0, 0) }}} This is shrunken by an amount of 1000. The result should be a triangle but it is not. See attached image where the input polygon is red and the result is green. " Bugs closed To Be Determined polygon Boost 1.55.0 Problem duplicate
