Class HotPixel

    java.lang.Object
      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.

Version:

Method Summary
`Coordinate` `getCoordinate()`
`Envelope` `getSafeEnvelope()` Returns a "safe" envelope that is guaranteed to contain the hot pixel
`boolean` `intersects(Coordinate p0, Coordinate p1)`
`boolean` `intersectsScaled(Coordinate p0, Coordinate p1)`
