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.

addSnappedNode
public boolean addSnappedNode(NodedSegmentString segStr,
int segIndex)
- Adds a new node (equal to the snap pt) to the specified segment
if the segment passes through the hot pixel
- Parameters:
segStr
- segIndex
-
- Returns:
- true if a node was added to the segment
