Possible Error

[some-vec-byte]

In Shapefile.cs Line 172: _boundingBox = new RectangleD(_mainHeader.XMin, _mainHeader.YMin, _mainHeader.XMax, _mainHeader.YMax);

Constructor of RectangleD: (double left, double top, double right, double bottom)

so shouldnt it be: _boundingBox = new RectangleD(_mainHeader.XMin, _mainHeader.YMax, _mainHeader.XMax, _mainHeader.YMin);

Greetings
