com.vividsolutions.jts.noding.snapround.HotPixel
public class HotPixel
extends java.lang.Object
Implements a "hot pixel" as used in the Snap Rounding algorithm.
A hot pixel contains the interior of the tolerance square and
the boundary
minus the top and right segments.
The hot pixel operations are all computed in the integer domain
to avoid rounding problems.
getSafeEnvelope
public Envelope getSafeEnvelope()
Returns a "safe" envelope that is guaranteed to contain the hot pixel
