Method Detail

snap

public boolean snap(HotPixel hotPixel,
                    SegmentString parentEdge,
                    int hotPixelVertexIndex)

Snaps (nodes) all interacting segments to this hot pixel. The hot pixel may represent a vertex of an edge, in which case this routine uses the optimization of not noding the vertex itself

Parameters:

hotPixel - the hot pixel to snap to

parentEdge - the edge containing the vertex, if applicable, or null

hotPixelVertexIndex - the index of the hotPixel vertex, if applicable, or -1

Returns:

true if a node was added for this pixel
