示例1: CleanPolygon
//------------------------------------------------------------------------------
public static Path CleanPolygon(Path path,
double distance = 1.415)
{
//distance = proximity in units/pixels below which vertices
//will be stripped. Default ~= sqrt(2) so when adjacent
//vertices have both x & y coords within 1 unit, then
//the second vertex will be stripped.
double distSqrd = (distance * distance);
int highI = path.Count -1;
Path result = new Path(highI + 1);
while (highI > 0 && PointsAreClose(path[highI], path[0], distSqrd)) highI--;
if (highI < 2) return result;
IntPoint pt = path[highI];
int i = 0;
for (;;)
{
while (i < highI && PointsAreClose(pt, path[i], distSqrd)) i+=2;
int i2 = i;
while (i < highI && (PointsAreClose(path[i], path[i + 1], distSqrd) ||
SlopesNearCollinear(pt, path[i], path[i + 1], distSqrd))) i++;

//------------------------------------------------------------------------------
internal static bool StripDupsAndGetBotPt(Path in_path,

{
